给定一个字符串,现在我们的任务是用该字符串替换指定的字符。该任务借助 Replace() 方法执行。此方法用于用指定的字符串替换所有 Unicode 字符,并返回修改后的字符串。

语法:

字符串。替换(字符,新字符串)

这里字符串是输入字符串,T3】一个字符出现在要替换的字符串中,new_string 是替换该字符的字符串。

示例:

Input: A portal in India
Replace A with Hello
Output: Hello portal in India

Input: Python is not equal to java
Replace is with was
Output: Python was not equal to java

进场:

要用指定的字符串替换字符,请执行以下步骤:

  • Declaration string
  • Use the replace () function to replace the character (that is, "a") with a string (that is, "geek represents geek").
input_string.Replace("A", "Geeks For Geeks")
  • Displays the modified string.

例:

c

// C# program to replace a character
// with a specified string
using System;

class GFG{

public static void Main()
{

    // Define string
    String input_string = "A portal in India";

    Console.WriteLine("Actual String : " + input_string);

    // Replace the string 'A' with 'Geeks For Geeks'
    Console.WriteLine("Replaced String: " +
         input_string.Replace("A", "Geeks For Geeks"));
}
}

输出:

Actual String : A portal in India
Replaced String: Geeks For Geeks portal in India
