VisualSVN 破解方法

第一步，首先準備反彙編工具 ildasm.exe,找到VisualSVN的安裝路徑，一般先備份，在備份裡面操作。

第二步，轉儲 ， 得到同名的il文件：VisualSVN.Core.L.il，用記事本打開得到的 VisualSVN.Core.L.il 文件，在其中搜索 “KeyToLicenseUnsafe”，找到KeyToLicenseUnsafe方法，大概在3296行附近。查找並替換成下麵的代碼，然後保存

.method public hidebysig static class VisualSVN.Core.Licensing.License
          KeyToLicenseUnsafe(class VisualSVN.Core.IDecoder decoder,
                             string key) cil managed
  {
    // 代碼大小       69 (0x45)
    .locals init (class VisualSVN.Core.Licensing.License V_0, class VisualSVN.Core.Licensing.License V_1, class VisualSVN.Core.Licensing.License V_2)
    IL_0000: nop
    IL_0001: newobj instance void VisualSVN.Core.Licensing.License::.ctor()
    IL_0006: stloc.1
    IL_0007: ldloc.1
    IL_0008: ldsfld valuetype [mscorlib]System.DateTime [mscorlib]System.DateTime::MinValue
    IL_000d: stfld valuetype [mscorlib]System.DateTime VisualSVN.Core.Licensing.License::StartTime
    IL_0012: ldloc.1
    IL_0013: ldc.i4.1
    IL_0014: stfld valuetype VisualSVN.Core.Licensing.LicenseBinding VisualSVN.Core.Licensing.License::Binding
    IL_0019: ldloc.1
    IL_001a: ldc.i4 0x7ffffffe
    IL_001f: stfld int32 VisualSVN.Core.Licensing.License::Capacity
    IL_0024: ldloc.1
    IL_0025: ldsfld valuetype [mscorlib]System.DateTime [mscorlib]System.DateTime::MaxValue
    IL_002a: stfld valuetype [mscorlib]System.DateTime VisualSVN.Core.Licensing.License::EndTime
    IL_002f: ldloc.1
    IL_0030: ldc.i4.2
    IL_0031: stfld valuetype VisualSVN.Core.Licensing.LicenseType VisualSVN.Core.Licensing.License::Type
    IL_0036: ldloc.1
    IL_0037: ldstr "100"
    IL_003c: stfld string VisualSVN.Core.Licensing.License::PurchaseId
    IL_0041: ldloc.1
    IL_0042: call string [mscorlib]System.Environment::get_UserName()
    IL_0047: stfld string VisualSVN.Core.Licensing.License::LicensedTo
    IL_004c: ldloc.1
    IL_004d: stloc.0
    IL_004e: ldloc.0
    IL_004f: ldloc.0
    IL_0050: ldfld valuetype [mscorlib]System.DateTime VisualSVN.Core.Licensing.License::StartTime
    IL_0055: stfld valuetype [mscorlib]System.DateTime VisualSVN.Core.Licensing.License::PurchaseDate
    IL_005a: ldloc.0
    IL_005b: stloc.2
    IL_005c: br.s
    IL_005e
    IL_005e:ldloc.2
    IL_005f: ret
  } // end of method LicenseConverter::KeyToLicenseUnsafe

第三步，用vs2015開發人員命令提示  ，然後覆蓋到 bin目錄 

用vs2015開發人員命令提示  運行如下代碼（換成自己的）

ilasm "C:\Program Files (x86)\VisualSVN\bins\VisualSVN.Core.L.il" /output="C:\Program Files (x86)\VisualSVN\bins\VisualSVN.Core.L.dll" /dll

 看到如下界面

表示編譯成功，然後把編譯好的VisualSVN.Core.L.dll 覆蓋到 bin目錄下就完成破解了。
