我需要在 IL 级别调试 dll，并阅读http://blogs.msdn.com/b/jmstall/archive/2004/10/03/237137.aspx我想用 il(d )asm。

拆卸通过，但重新组装失败

Assembled method Dapper.SqlMapper°UdtTypeHandler::Dapper.SqlMapper.ITypeHandler.SetValue
Assembled method Dapper.SqlMapper°TypeHandler`1::Dapper.SqlMapper.ITypeHandler.SetValue
Assembled method Dapper.SqlMapper°TypeHandler`1::Dapper.SqlMapper.ITypeHandler.Parse
Assembled method Dapper.SqlMapper°TypeHandler`1::.ctor
Assembled method Dapper.SqlMapper°Link`2::TryGet
W:\TimPrecast\ildasm\ppdbcore.il(71204) : error : Undeclared identifier IL_0016
W:\TimPrecast\ildasm\ppdbcore.il(71204) : error : syntax error at token ':' in:       IL_0016:  ldloc.s

***** FAILURE *****

然后我打开 ILSpy 中的 DLL 和记事本中生成的 IL 文件：

ILSpy：

    IL_000a: stloc.1
    IL_000b: ldloc.1
    IL_000c: ldarg.1
    IL_000d: ldloca.s found
    IL_000f: call bool class Dapper.SqlMapper/Link`2<!TKey, !TValue>::TryGet(class Dapper.SqlMapper/Link`2<!0, !1>, !0, !1&)
    IL_0014: stloc.s 4
    IL_0016: ldloc.s 4
    IL_0018: brfalse.s IL_0027

    IL_001a: nop
    IL_001b: ldarg.2
    IL_001c: ldloc.2
    IL_001d: stobj !TValue
    IL_0022: ldc.i4.0
    IL_0023: stloc.s 5
    IL_0025: br.s IL_0051

ILDASM（第 71204 行是 IL_0016）：

  IL_000a:  stloc.1
  IL_000b:  ldloc.1
  IL_000c:  ldarg.1
  IL_000d:  ldloca.s   found
  IL_000f:  call       bool class Dapper.SqlMapper/Link`2<!TKey,!TValue>::TryGet(class Dapper.SqlMapper/Link`2<!0,!1>,
                                                                                 !0,
                                                                                 !1&)
  IL_0014:  stloc.s    
  IL_0016:  ldloc.s    
  IL_0018:  brfalse.s  IL_0027

  IL_001a:  nop
  IL_001b:  ldarg.2
  IL_001c:  ldloc.2
  IL_001d:  stobj      !TValue
  IL_0022:  ldc.i4.0
  IL_0023:  stloc.s    V_5
  IL_0025:  br.s       IL_0051

似乎缺少 stloc.s 的索引。
