如何通过 ILGenerator.Emit* 调用'normal'方法？

Question

DynamicMethod是否可以通过ILGenerator。EmitCall—或类似—例如)一个"正常"的方法，例如Private Sub BlahBlah(ByVal obj as Object)?

Thanks in advance

Answer 1

将赋值堆栈上的值赋给方法

MethodInfo methodInfo = typeof(ClassName).GetMethod(MethodName, new Type[1] { typeof(-method argument types-) });
IL.Emit(OpCodes.Call, methodInfo );

Answer 2

delegate void foo();
public static void show(string foo)
{
    MessageBox.Show(foo);
}
public void test()
{
    DynamicMethod dm = new DynamicMethod("foo", null, null);
    ILGenerator gen = dm.GetILGenerator();
    gen.Emit(OpCodes.Ldstr, "hello world");
    gen.EmitCall(OpCodes.Call, this.GetType().GetMethod("show"),null);
    gen.Emit(OpCodes.Ret);
    var b = dm.CreateDelegate(typeof(foo)) as foo;
    b();
}
