首先,设置StringBuilder-
StringBuilder str = new StringBuilder(); str.Append("premium");
要访问第五个字符并显示它-
Console.WriteLine(str[4]);
以下是完整的代码-
using System; using System.Text; public class Demo { public static void Main() { StringBuilder str = new StringBuilder(); str.Append("premium"); Console.WriteLine("String : "+str); Console.Write("Accessing 5th character : "); Console.WriteLine(str[4]); } }
输出结果
String : premium Accessing 5th character : i
