推荐答案

using System;
using System.Reflection;

//...

static int CountPublicMembers(Assembly assembly) {
    int result = 0;
    Type[] types = assembly.GetTypes();
    foreach (Type type in types)
        result += type.GetMembers().Length;
    return result;
} //CountPublicMembers

static void CountAll() {
    Assembly mscorelib = typeof(System.String).Assembly;
    Assembly systemCore = typeof(System.Action).Assembly;
    int iMscorelib = CountPublicMembers(mscorelib);
    int iSystemCore = CountPublicMembers(systemCore);
    System.Console.WriteLine(
        "{0}+{1} = {2}",
        iMscorelib, iSystemCore,
        iMscorelib + iSystemCore);
} //CountAll

—SA

string str = "YourStringValues";
  str = str.Substring(str.Length - 2); // Passing parameter Zero based starting character position of substring.
Console.WriteLine(str);  // Print Last two Character eg:- es

输出:-es

output :- es
