C# 讀寫網上鄰居中的共用文件

讀寫網上鄰居共用的文件夾，和操作本地文件夾類似，只要有許可權讀取寫入即可。

分為以下2步：

1.打通共用文件夾許可權

2.操作文件

打通共用文件夾許可權

 1         /// <summary>
 2         /// 連接共用文件
 3         /// </summary>
 4         /// <param name="path">共用文件地址</param>
 5         /// <param name="userName">用戶名</param>
 6         /// <param name="passWord">密碼</param>
 7         /// <returns>true:連接成功 false:連接失敗</returns>
 8         public static bool ConnectState(string path, string userName, string passWord)
 9         {
10             bool Flag = false;
11             Process proc = new Process();
12             try
13             {
14                 proc.StartInfo.FileName = "cmd.exe";
15                 proc.StartInfo.UseShellExecute = false;
16                 proc.StartInfo.RedirectStandardInput = true;
17                 proc.StartInfo.RedirectStandardOutput = true;
18                 proc.StartInfo.RedirectStandardError = true;
19                 proc.StartInfo.CreateNoWindow = true;
20                 proc.Start();
21                 string dosLine = @"net use " + path + " /User:" + userName + " " + passWord + " /PERSISTENT:YES";
22                 proc.StandardInput.WriteLine(dosLine);
23                 proc.StandardInput.WriteLine("exit");
24                 while (!proc.HasExited)
25                 {
26                     proc.WaitForExit(1000);
27                 }
28                 string errormsg = proc.StandardError.ReadToEnd();
29                 proc.StandardError.Close();
30                 if (string.IsNullOrEmpty(errormsg))
31                 {
32                     Flag = true;
33                 }
34                 else
35                 {
36                     throw new Exception(errormsg);
37                 }
38             }
39             catch (Exception ex)
40             {
41                 throw ex;
42             }
43             finally
44             {
45                 proc.Close();
46                 proc.Dispose();
47             }
48 
49             return Flag;
50         }

創建文件夾

1 DirectoryInfo dirInfo = new DirectoryInfo("\\WIN-R3377JMR1LG\ShareFolder");
2 if (dirInfo.Exists == false)
3 {
4     dirInfo.Create();
5 }

上傳文件

 1         /// <summary>
 2         /// 上傳文件到共用文件夾
 3         /// </summary>
 4         /// <param name="sourceFile">本地文件</param>
 5         /// <param name="remoteFile">遠程文件</param>
 6         public static void UpLoadFile(string sourceFile, string remoteFile)
 7         {
 8             //判斷文件夾是否存在 ->不存在則創建
 9             var targetFolder = Path.GetDirectoryName(remoteFile);
10             DirectoryInfo theFolder = new DirectoryInfo(targetFolder);
11             if (theFolder.Exists == false)
12             {
13                 theFolder.Create();
14             }
15

17             {
18                 WebClient myWebClient = new WebClient();
19                 NetworkCredential cread = new NetworkCredential();
20                 myWebClient.Credentials = cread;
21 
22                 using (FileStream fs = new FileStream(sourceFile, FileMode.Open, FileAccess.Read))
23                 {
24                     using (BinaryReader r = new BinaryReader(fs))
25                     {
26                         byte[] postArray = r.ReadBytes((int)fs.Length);
27                         using (Stream postStream = myWebClient.OpenWrite(remoteFile))
28                         {
29                             if (postStream.CanWrite == false)
30                             {
31                                 LogUtil.Error($"{remoteFile} 文件不允許寫入~");
32                                 return;
33                             }
34 
35                             postStream.Write(postArray, 0, postArray.Length);
36                         }
37                     }
38                 }
39             }
40             catch (Exception ex)
41             {
42                 string errMsg = $"{remoteFile}  ex:{ex.ToString()}";
43                 LogUtil.Error(errMsg);
44                 Console.WriteLine(errMsg);
45             }
46         }
