Finalize方法的生成

Finalize在c#编程语言中需要特殊语法，因此，c#要求在类名前加~符号来定义Finalize方法：例如

internal class FinalizeDemo
    {
        ~FinalizeDemo()
        {
            int num = GC.MaxGeneration;
        }
    }

ILDasm.exe所在目录

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6 Tools

使用ILDasm.exe查看Finalize生成的中间语言

.method family hidebysig virtual instance void
        Finalize() cil managed
{
  .override [mscorlib]System.Object::Finalize
  // 代码大小       19 (0x13)
  .maxstack  1
  .locals init ([0] int32 num)
  IL_0000:  nop
  .try
  {
    IL_0001:  nop
    IL_0002:  call       int32 [mscorlib]System.GC::get_MaxGeneration()
    IL_0007:  stloc.0
    IL_0008:  leave.s    IL_0012
  }  // end .try
  finally
  {
    IL_000a:  ldarg.0
    IL_000b:  call       instance void [mscorlib]System.Object::Finalize()
    IL_0010:  nop
    IL_0011:  endfinally
  }  // end handler
  IL_0012:  ret
} // end of method FinalizeDemo::Finalize
