带C#示例的String.Inequality（！=）运算符
C＃String.Inequality运算子
“！=”是C＃中的String.Inequality运算符，用于检查两个字符串对象是否具有相同的值（如果字符串不具有相同的值，则返回true）。
语法：
public static bool operator != (string a, string b);
参数：它有两个参数都是要比较的字符串。
返回值：bool-返回布尔值。如果字符串具有相同的值，则返回false，否则返回true。
示例
Input:
string str1 = "nhooo";
string str2 = "nhooo";
String.Inequality:
str1 != str2;
Output:
falseC＃使用String.Inequality（！=）运算符比较两个字符串的示例
using System;
using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
string str1 = "nhooo";
string str2 = "nhooo";
//比较字符串
Console.WriteLine("str1!=str2: " + (str1 != str2));
if (str1 != str2)
Console.WriteLine("str1 and str2 don't have the same values");
else
Console.WriteLine("str1 and str2 have the same values");
str1 = "Hello world";
str2 = "nhooo";
//比较字符串
Console.WriteLine("str1!=str2: " + (str1 != str2));
if (str1 != str2)
Console.WriteLine("str1 and str2 don't have the same values");
else
Console.WriteLine("str1 and str2 have the same values");
//按ENTER退出
Console.ReadLine();
}
}
}输出结果
str1!=str2: False str1 and str2 have the same values str1!=str2: True str1 and str2 don't have the same values
