.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反編譯相同的函數,代碼如下:
.method private hidebysig static void? Main() cil managed
{
? .entrypoint //注意這個
? .custom instance void [mscorlib]System.STAThreadAttribute::.ctor() =
( 01 00 00 00 )
? // 代碼大小?????? 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反編譯的代碼沒有.entrypoint,由于才開始接觸這方面的知識,
在《Inside MICROSOFT .NET IL Assembler》(電子版)
中找到對.entrypoint的說明:
.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.
看來還是.net自帶的工具保險些
