MSIL(1): Hello World

1. 用记事本编写如下代码

.assembly HelloWorld{}

.assembly extern mscorlib{}

.class HelloWorld extends [mscorlib]System.Object

{

  .method public static void HelloWorld()

  {

    .maxstack 1

    ldstr "Hello World"

    call void [mscorlib]System.Console::WriteLine(string)

    ret

  }

  .method public static void main()

  {

     .entrypoint

     .maxstack 1

     call void HelloWorld::HelloWorld()

     ret

   }

}

2. 将以上代码保存为ilhelloworld.il,然后运行ilasm.exe 将il编译为exe

3. 执行这个exe文件，我们看到输出Hello World
