示例1: Main

//引入命名空间
using System;
using System.Reflection;

public class Example

    public static void Main()
    {
        // Get method body information.
        MethodInfo mi = typeof(Example).GetMethod("MethodBodyExample");
        MethodBody mb = mi.GetMethodBody();

        // MethodBody object.

        // Display information about the local variables in the
        // method body.

        // from the ArgumentException class. 
        // Other exceptions, including ArgumentException itself, 
        // are not handled by this filter clause.
