Example 1: C# String Replace() Characters using System; namespace CsharpString { class Test { public static void Main(string [] args) { string str = "Bat"; Console.WriteLine("Old value: " + str); string result; // replaces 'B' with 'C'' result = str.Replace('B', 'C'); ...
strings ="aaa"; Console.WriteLine($"The initial string: '{s}'"); s = s.Replace("a","b").Replace("b","c").Replace("c","d"); Console.WriteLine($"The final string: '{s}'");// The example displays the following output:// The initial string: 'aaa'// The final string: '...
Replaces each substring of this string that matches the literal target string with the specified literal replacement string. The replacement proceeds from the beginning of the string to the end, for example, replacing "aa" with "b" in the string "aaa" will result in "ba" rather than "ab"...
string s = new('a', 3); Console.WriteLine($"The initial string: '{s}'"); s = s.Replace('a', 'b').Replace('b', 'c').Replace('c', 'd'); Console.WriteLine($"The final string: '{s}'"); // The example displays the following output: // The initial string: 'aaa' //...
// replace signatures used in the same order as described above: // Using positions: 0123456789*123456789*12345 std::string str=base; // "this is a test string." //第9个字符以及后面的4个字符被str2代替 str.replace(9,5,str2); // "this is an example string." (1) ...
set replaced [string replace str [string first oldStr str] [string last oldStr str] newStr] puts replaced 在上面的示例中,我们首先定义了一个变量`oldStr`,存储了要替换的子字符串"Hello"。然后,我们定义了一个变量`newStr`,存储了替换后的字符串"Goodbye"。接下来,我们使用string first和string last命...
Python使用replace()函数来实现字符串的替换,其语法为: str.replace(old, new[, max]) old -- 将被替换的子字符串。 new -- 新字符串,用于替换old子字符串。 max -- 可选字符串, 替换不超过 max 次 执行成功后,返回替换后的新字符串。 比如下面的实例,我们将 “hello,world!”替换为 “hello,python...
