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
}
.assembly test

ilasm一下,可以构建成功并运行出现一个窗体;下回继续;
