C＃使用String.Compare()方法比较两个字符串的示例 (C# Example to compare two strings using String.Compare() method)

using System;
using System.Text;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            //string variables
            string str1 = "IncludeHelp";
            string str2 = "IncludeHelp";

            Console.WriteLine(String.Compare("ABCD", "ABCD"));
            Console.WriteLine(String.Compare("ABCD", "abcd"));
            Console.WriteLine(String.Compare("abcd", "ABCD"));

            //checking the condition
            if (String.Compare(str1, str2)==0)
                Console.WriteLine(str1 + " and " + str2 + " are same");
            else
                Console.WriteLine(str1 + " and " + str2 + " are not same");

            str1 = "INCLUDEHELP";
            str2 = "IncludeHelp";

            if (String.Compare(str1, str2) == 0)
                Console.WriteLine(str1 + " and " + str2 + " are same");
            else
                Console.WriteLine(str1 + " and " + str2 + " are not same");
