添加一种emit的应用，反射发出，较直接调用稍慢，但好过反射与表达式树。

System.Reflection.MethodInfo mInfo = typeof(TypeParse).GetMethod("Add", 
System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);

[Serializable]
void Main()
{
var addMethod = typeof(MyMath).GetMethod("Add");
var dynamicMethod = new DynamicMethod("", typeof(int), new[] { typeof(MyMath), typeof(int), typeof(int) });
//
var il = dynamicMethod.GetILGenerator();
il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Ldarg_1);
il.Emit(OpCodes.Ldarg_2);
il.Emit(OpCodes.Callvirt, addMethod);
il.Emit(OpCodes.Ret);
//
var add = (Func<MyMath, int, int, int>)dynamicMethod.CreateDelegate(typeof(Func<MyMath, int, int, int>));
//
var math = new MyMath();
var result = add(math, 1, 2);


	var method=MethodBase.GetCurrentMethod();
	Console.WriteLine (method.Name);
	var body=method.GetMethodBody();
	var attrs=method.CustomAttributes;
	foreach (var attr in attrs)
	{
		Console.WriteLine (attr.AttributeType);
	}
	Console.WriteLine (body.GetILAsByteArray());
	var pars=method.GetParameters();
	foreach (var param in pars)
	{
		Console.WriteLine (param.Name);
	}
}


// Define other methods and classes here
string Get(){
return "dd";}
public class MyMath {
    public int Add(int a, int b) { return a + b; }
}
}
class SerializableAttribute :System.Attribute{
public SerializableAttribute()
