網路上資源很多不全面，自己在開發的時候走了不少彎路，在這裡整理了最全面的google全套開發，COM交互，web端交互。封裝好了各種模塊功能。直接就可以調用。

第一種方式：調用COMAPI實現調用google地球

1、安裝googleearth客戶端。傳送門：https://pan.baidu.com/s/1xi3fwCIy3Jt6t5XbypqpCg 提取碼：0l7u

2、添加引用using EARTHLib;如果找不到此dll，到googleearth的安裝目錄下尋找後添加到引用即可。

3、添加預定義的方法到項目中，後續獲取視窗句柄，以及設置視窗的時候會調用其中的一些方法。

    class NativeMethods
    {
         [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
         public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int x, int y, int cx, int cy, UInt32 uflags);
  
         [DllImport("user32.dll", CharSet = CharSet.Auto)]
         public static extern IntPtr PostMessage(int hWnd, int msg, int wParam, int lParam);
  
         #region 預定義
  
         public static readonly IntPtr HWND_BOTTOM = new IntPtr(1);
         public static readonly IntPtr HWND_NOTOPMOST = new IntPtr(-2);
         public static readonly IntPtr HWND_TOP = new IntPtr(0);
         public static readonly IntPtr HWND_TOPMOST = new IntPtr(-1);

         public static readonly UInt32 SWP_NOSIZE = 1;
         public static readonly UInt32 SWP_NOMOVE = 2;
         public static readonly UInt32 SWP_NOZORDER = 4;
         public static readonly UInt32 SWP_NOREDRAW = 8;
         public static readonly UInt32 SWP_NOACTIVATE = 16;
         public static readonly UInt32 SWP_FRAMECHANGED = 32;
         public static readonly UInt32 SWP_SHOWWINDOW = 64;
         public static readonly UInt32 SWP_HIDEWINDOW = 128;
         public static readonly UInt32 SWP_NOCOPYBITS = 256;
         public static readonly UInt32 SWP_NOOWNERZORDER = 512;
         public static readonly UInt32 SWP_NOSENDCHANGING = 1024;
  
         #endregion
  
         public delegate int EnumWindowsProc(IntPtr hwnd, int lParam);
  
         [DllImport("user32", CharSet = CharSet.Auto)]
         public extern static IntPtr GetParent(IntPtr hWnd);
  
         [DllImport("user32", CharSet = CharSet.Auto)]
         public extern static bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);
  
         [DllImport("user32", CharSet = CharSet.Auto)]
         public extern static IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
  
         [DllImport("user32.dll", ExactSpelling = true, CharSet = CharSet.Auto)]
         public static extern IntPtr GetWindow(IntPtr hWnd, int uCmd);
  
         public static int GW_CHILD = 5;
         public static int GW_HWNDNEXT = 2;
     }

4、定義變數

        private bool isGEStart = false;//GE是否開啟
        private ApplicationGEClass geApp;
        /// <summary>
        /// 用來關閉GoogleEarth的消息定義
        /// </summary>
        static readonly Int32 WM_QUIT = 0x0012;

        private IntPtr GEHWnd = (IntPtr)5;
        private IntPtr GEHrender = (IntPtr)5;
        private IntPtr GEParentHrender = (IntPtr)5;

5、做完上面的工作後，開始初始化谷歌地球。將下列代碼放入自己定義的方法中即可。

try
            {
                if (!this.DesignMode)
                {
                    geApp = new ApplicationGEClass();

                    GEHWnd = (IntPtr)geApp.GetMainHwnd();
                    //隱藏GoogleEarth主視窗
                    NativeMethods.SetWindowPos(GEHWnd, NativeMethods.HWND_BOTTOM, 0, 0, 0, 0, NativeMethods.SWP_NOSIZE + NativeMethods.SWP_HIDEWINDOW);

                    GEHrender = (IntPtr)geApp.GetRenderHwnd();
                    GEParentHrender = (IntPtr)NativeMethods.GetParent(GEHrender);
                    //將渲染視窗嵌入到主窗體
                    NativeMethods.MoveWindow(GEHrender, 0, 0, this.panelEx_google.Size.Width, this.panelEx_google.Size.Height, true);
                    NativeMethods.SetParent(GEHrender, this.panelEx_google.Handle);
                    isGEStart = true;
                   
                }
            }
            catch (Exception ex)
            {
                
                isGEStart = false;
                Thread.Sleep(1000);
            }

6、以上代碼可載入谷歌地球，並且釋放資源，程式運行如圖：

第一種方式實質上是啟動GoogleEarth客戶端，並獲取視窗句柄，再將視窗顯示的自己定義的控制項下麵，此種方法也可以實現需求，但是經過測試，此方法存在兩大弊端。第一，在啟動谷歌地球的時候將占用大量的CPU資源。第二、在釋放谷歌地球的時候時候，可能會釋放失敗，無法關閉googleearth此時也將占用大量的CPU。基於以上弊端所以採用第二種方式。webroswer調用js。

2、重點：乾貨。

c#使用GEPlugin插件,webroswer與js交互，實現web端的googleearth體驗。並且載入kml，載入三維模型dae，載入路徑，電子圍欄。各種功能已封裝。調用即可使用。

1、下載GEPlugin 傳送門：

鏈接：https://pan.baidu.com/s/1e_elo_x0KlhfFgNzbboa6w
提取碼：687b

2、使用GEPlugin相對於COMAPI要較為複雜。但是性能最優。下載封裝好的文件，單獨的exe，放在程式項目文件中，啟動這個文件，在程式中調用一個方法即可載入google地球到webroswer。因為這個文件有公司logo。所以不便發佈於此，有想要的可以私信我。單獨發送。謹記：此文件只供學習使用，交流心得，不得用於任何商業行為。

3、下麵開始正式的編碼。如果下載了exe的文件，並且打開後，執行此段代碼，谷歌地球將被載入完成。獲取的硬碟id以及cpu序列號，將此數據傳遞到封裝好的服務中。防止別的瀏覽器直接輸入網址瀏覽。安全校驗使用。

並且將你的form設置成對COM可見

                    }
                ));
            }));
            //啟動GoogleEarth裝載的線程
            geLazyLoadingThread.SetApartmentState(ApartmentState.STA);
            geLazyLoadingThread.Start();
        }

private string GetDiskID()
{
try
{
//獲取硬碟ID
String HDid = " ";
ManagementClass mc = new ManagementClass("Win32_DiskDrive");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
HDid = (string)mo.Properties["Model"].Value;

moc = null;
mc = null;
return HDid;

finally

}

return cpuInfo;
}
catch
{
return "unknown";
}
finally
{
}

}

4、此時地圖即可載入完成，萬水千山，踏出第一步。但是此時無法向谷歌地球添加kml或者三維模型。和一些其他的操作。如果要載入kml文件。繼續往下看。

5、此時啟動web容器，先添加引用 CassiniDev4-lib；找不到又不想下載？傳送門來了：

            WEBSERVER_PATH = string.Concat(new object[] { Directory.GetCurrentDirectory(), Path.DirectorySeparatorChar, "3DView" });

            _server1 = new CassiniDev.Server(9630, "/", WEBSERVER_PATH,
                     System.Net.IPAddress.Parse("127.0.0.1"), "", false, true);

            if (!IsWebServerStarted)
            {
                try
                {
                    _server1.Start();
                    IsWebServerStarted = true;

                {
                    MessageBox.Show( "服務打開失敗！", "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
                    _server1.Dispose();
                    return;
                }
                /*
                try
                {

                    _server2.Dispose();
                    return;
                }
                */
            }
            else
            {
                try
                {
                    _server1.ShutDown();
                    IsWebServerStarted = false;
                }
                catch (Exception ex)

                    _server1.Dispose();
                    //return;
                }

                try
                {
                    _server1.Start();
                    IsWebServerStarted = true;
                }
                catch (Exception ex)
                {
                    MessageBox.Show( "服務打開失敗！", "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
                    _server1.Dispose();
                    return;
                }
            }
        }

6、此時小伙伴要問，為什麼要啟動一個web服務，不要著急，往下看。載入kml文件。

webBrowserGE.Document.InvokeScript("importLidarKmlFilebyUrl", new object[] { "http://127.0.0.1:9630/3DMap/zouhang1.kml",true });

是不是很神奇，只需要一行代碼，你的kml文件，或者kml文件中帶有有三維模型的文件，即可被載入成功，因為程式已經完全封裝了你所需要的功能。

解析上一個疑惑，為什麼要啟動一個web服務，因為invokescprit載入文件的時候需要以網址的形式載入，所以啟動一個web伺服器，並設置好root目錄，將你的kml文件放置到root目錄下即可。

7、你以為此時kml文件就可以載入成功了？成功的道路總是充滿坎坷的。此時的你載入kml的時候，應該是看不到任何反應的。因為我當初在這個地方踩了很多的坑。你們很幸運，不需要在這裡掙扎。記錄一下。分享給你們。

///重要重要重要        

public string getMapServerandLag_callback()
        {
            return "7,1,18";
        }

多麼簡單的一個方法，但是沒有他你什麼也做不了。這個是地圖載入後的回調方法。務必加上。用於給層級賦值。

下麵還有幾個方法，分享給你門，可有可無。

//載入失敗後的回調函數       
public void JSInitFailureCallback_(string error){
}
        　　
//載入成功後的回調函數

public void geSuccessLoadedCallback_()
{

}

8、經過以上的努力你已經達成了目標的80%了。你所想要的功能已經基本實現。

另外一些其他的載入方法在這裡附上

                webBrowserGE.Document.InvokeScript("importGoogleMapKmlFilebyUrl", new object[] { "http://127.0.0.1:9630/3DMap/ditu.kml" });
                webBrowserGE.Document.InvokeScript("importLidarKmlFilebyUrl", new object[] { "http://127.0.0.1:9630/3DMap/zouhang1.kml",true });
                webBrowserGE.Document.InvokeScript("importRemarkKmlFilebyUrl", new object[] { "http://127.0.0.1:9630/3DMap/1111.kml" });
                webBrowserGE.Document.InvokeScript("importDrawKmlFilebyUrl", new object[] { "http://127.0.0.1:9630/3DMap/1111.kml" });
                webBrowserGE.Document.InvokeScript("importLidarKmlFilebyUrl", new object[] { "http://127.0.0.1:9630/3DMap/1111.kml", true });
                webBrowserGE.Document.InvokeScript("importDrawKmlFilebyUrl", new object[] { "http://192.168.1.196:9630/3DPaint/KmlDrawings/1111.kml", true });
                webBrowserGE.Document.InvokeScript("searchLocation_e", new object[] { 38, 117 });
                webBrowserGE.Document.InvokeScript("importLidarKmlFilebyUrl", new object[] { "http://127.0.0.1:9630/3DMap/111.kml" });

                webBrowserGE.Document.InvokeScript("getGEKml_e");
                webBrowserGE.Document.InvokeScript("setMapLayersStatus", new object[] { false, false, false, false, false, false, false, false, false, false, false, false });

非常簡單，可自己摸索。

9、上圖

到這裡就結束了？不存在的。技術用於之境。下麵分享給大家，如何將二維高德地圖蒙皮到三維谷歌球體上。拭目以待。

10、載入高德地圖到谷歌地球上。實現谷歌地球與高德地圖之間的切換。
