C#程序,用于更改字符串中的字符
假设我们的字符串是-
StringBuilder str = new StringBuilder(); str.Append("pre");
要更改字符,请在该特定索引处设置值。以下将字符设置在第3个位置-
str[2] = 'o';
这是完整的代码-
示例
using System; using System.Text; public class Demo { public static void Main() { StringBuilder str = new StringBuilder(); str.Append("pre"); Console.WriteLine("String : "+str); Console.WriteLine("Change 3rd character"); str[2] = 'o'; Console.WriteLine("New String : "+str); } }
输出结果
String : pre Change 3rd character New String : pro
