IL汇编语言做一个窗体

网上看到一段代码，

.assembly extern

mscorlib {} .assembly Classes

{ .ver 1:0:1:0    } 

.namespace MyForm
{
    .class public TestForm extends 
        [System.Windows.Forms]System.Windows.Forms.Form
    {
        .field private class [System]System.ComponentModel.IContainer components
        .method public static void Main() cil managed
        {
            .entrypoint
            .maxstack  1
        
            //Create New Object of TestForm Class and Call the Constructor     
            newobj     instance void MyForm.TestForm::.ctor()
            call       void [System.Windows.Forms]
              System.Windows.Forms.Application::Run(
              class [System.Windows.Forms]System.Windows.Forms.Form)
             ret
        }
    }
}

似乎是做一个窗体出来；拿去构建一下，没什么效果；光有这一段应该是还不能做出窗体；

用VS做一个窗体exe，然后ildasm，加/text参数，获取全部的il代码保存下来；

看一下代码相当多；

逐步的删除一些，只要先构建通过，运行出现一个窗体即可；

资源相关的删掉；

.assembly test { ... } 整个这一段删掉；

 

可以构建成功，但是运行窗体不会出现；那保留这一段；

 

dispose删掉，销毁先不管；

 

资源Resource相关的删掉，应该没什么资源，

 

Culture相关的删掉，不知道是什么，

 

Settings相关的删掉，一个窗体没有用到，

 

一直删到这里，

 

下面看上去是Properties里有个Resources类，删掉，

 

.assembly test { ... } 里面看一下，版权和版本相关的删掉，

 

 

 到此剩下的代码如下，

.assembly extern System.Windows.Forms
{.publickeytoken = (B7 7A 5C 56 19 34 E0 89 )                         // .z\V.4...ver 4:0:0:0
}
.assembly extern mscorlib
{.publickeytoken = (B7 7A 5C 56 19 34 E0 89 )                         // .z\V.4...ver 4:0:0:0
}
.assembly extern System
{.publickeytoken = (B7 7A 5C 56 19 34 E0 89 )                         // .z\V.4...ver 4:0:0:0

ilasm一下，可以构建成功并运行出现一个窗体；下回继续；
