如何在C#中查找StringBuilder的长度()

StringBuilder.Length属性用于获取或设置当前StringBuilder对象的长度。

【如何在C#中查找StringBuilder的长度()】语法:public int Length {get; set; }返回当前实例的长度。
异常:如果为set操作指定的值小于零或大于MaxCapacity, 则此属性将提供ArgumentOutOfRangeException。
下面的程序说明了上面讨论的属性的用法:
示例1:
//C# program to demonstrate //the Length() Property using System; using System.Text; class GFG {//Main Method public static void Main(String[] args) {//create a StringBuilder object //with a String passed as parameter StringBuilder str = new StringBuilder( "WelcomeGeeks" ); //print string Console.WriteLine( "String = " + str.ToString()); //get length of StringBuilder object int length = str.Length; //print length Console.WriteLine( "length of String = " + length); } }

输出如下:
String = WelcomeGeeks length of String = 12

示例2:
//C# program to demonstrate //the Length() Property using System; using System.Text; class GFG { public static void Main(String[] args) {//create a StringBuilder object //with a String passed as parameter StringBuilder str = new StringBuilder( "India is Great" ); //print string Console.WriteLine( "String = " + str.ToString()); //get length of StringBuilder object int length = str.Length; //print length Console.WriteLine( "length of String = " + length); } }

输出如下:
String = India is Great length of String = 14
