.method private hidebysig static void Main() cil managed
{
.custom instance void [mscorlib]System.STAThreadAttribute::.ctor()
// Code Size: 11 byte(s)
.maxstack 1
L_0000: newobj instance void TestIL.Form1::.ctor()
L_0005: call void [System.Windows.Forms]System.Windows.Forms.
Application::Run([System.Windows.Forms]System.Windows.Forms.Form)
L_000a: ret
}
又使用ILDASM反编译相同的函数，代码如下：
.method private hidebysig static void Main() cil managed
{
.entrypoint //注意这个
.custom instance void [mscorlib]System.STAThreadAttribute::.ctor() =
( 01 00 00 00 )
// 代码大小 11 (0xb)
.maxstack 1
IL_0000: newobj instance void TestIL.Form1::.ctor()
IL_0005: call void [System.Windows.Forms]System.Windows.Forms.
Application::Run(class [System.Windows.Forms]System.Windows.Forms.Form)
IL_000a: ret
} // end of method Form1::Main
Reflector反编译的代码没有.entrypoint，由于才开始接触这方面的知识，
在《Inside MICROSOFT .NET IL Assembler》（电子版）
中找到对.entrypoint的说明：
.entrypoint identifies the current method as the entry point of the
application (the assembly). Each managed EXE file must have a single
entry point.The ILAsm compiler will refuse to compile a module without
a specified entry point, unless you use the /DLL command-line option.
看来还是.net自带的工具保险些 |
