VisualSVN 破解方法

第一步，首先准备反汇编工具 ildasm.exe,找到visualsvn的安装路径，一般先备份，在备份里面操作。

第二步，转储 ， 得到同名的il文件：visualsvn.core.l.il，用记事本打开得到的 visualsvn.core.l.il 文件，在其中搜索 “keytolicenseunsafe”，找到keytolicenseunsafe方法，大概在3296行附近。查找并替换成下面的代码，然后保存

.method public hidebysig static class visualsvn.core.licensing.license
          keytolicenseunsafe(class visualsvn.core.idecoder decoder,
                             string key) cil managed
  {
    // 代码大小       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开发人员命令提示  ，然后覆盖到 bin目录 

 

用vs2015开发人员命令提示  运行如下代码（换成自己的）

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

表示编译成功，然后把编译好的visualsvn.core.l.dll 覆盖到 bin目录下就完成破解了。
