Finalize在c#程式語言中需要特殊語法，因此，c#要求在類名前加~符號來定義Finalize方法：例如

internal class FinalizeDemo

    {

        ~FinalizeDemo()

        {

            int num = GC.MaxGeneration;

        }

    }

ILDasm.exe所在目錄

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

使用ILDasm.exe檢視Finalize生成的中間語言

.method family hidebysig virtual instance void

        Finalize() cil managed

{

  .override [mscorlib]System.Object::Finalize

  // 程式碼大小       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
