C# 中字符串切片旋转字符串

假设我们的字符串是 −
var str = "welcome";
如果只想旋转部分字符，请使用 substring() 方法及其后续代码。这里我们只旋转 2 个字符 −
var res = str.Substring(1, str.Length - 1) + str.Substring(0, 2);
以下是完整代码 −
示例
using System;
public class Program {
public static void Main() {
var str = "welcome";
Console.WriteLine("Original String = "+str);
var res = str.Substring(1, str.Length - 1) + str.Substring(0, 2);
Console.WriteLine("Rotating two characters in the String: "+res);
}
}
输出
Original String = welcome Rotating two characters in the String: elcomewe
