c#给定编码中的字符无效

Input two strings and check whether they are equal or not using C# program.

输入两个字符串，并使用C＃程序检查它们是否相等。

用于字符串比较的C＃代码 (C# code for string comparison)

Here, we are asking for two strings input from the user and checking them whether they are equal or not using == operator and also ignoring the case.

在这里，我们要求用户输入两个字符串，并使用==运算符检查它们是否相等，并且忽略大小写。

// C# program to check given strings are equal or not 
// using equal to (==) operator
using System;
using System.IO;
using System.Text;
namespace IncludeHelp
{
class Test
{
// Main Method 
static void Main(string[] args)
{
string str1;
string str2;
//input strings
Console.Write("Enter a string: ");
str1 = Console.ReadLine();
Console.Write("Enter another string: ");
str2 = Console.ReadLine();
//comparing strings 
if (str1 == str2)
Console.WriteLine("\"{0}\" and \"{1}\" are equal", str1, str2);
else
Console.WriteLine("\"{0}\" and \"{1}\" are not equal", str1, str2);
//another way 
if ((str1 == str2) == true)
Console.WriteLine("\"{0}\" and \"{1}\" are equal", str1, str2);
else
Console.WriteLine("\"{0}\" and \"{1}\" are not equal", str1, str2);
//comparing by ignoring the case 
//convert both strings in the same case 
//either in uppercase or lowercase
Console.WriteLine("By ignoring case...");
if(str1.ToUpper() == str2.ToUpper())
Console.WriteLine("\"{0}\" and \"{1}\" are equal", str1, str2);
else
Console.WriteLine("\"{0}\" and \"{1}\" are not equal", str1, str2);
//hit ENTER to exit the program
Console.ReadLine();
}
}
}
