StringBuilder.Length属性用于获取或设置当前StringBuilder对象的长度。
Syntax: public int Length { get; set; }
It returns the length of the current instance.
Exception: This property will give ArgumentOutOfRangeException if the value specified for a set operation is less than zero or greater than MaxCapacity.
下面的程序说明了上面讨论的属性的用法：
范例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：
String = WelcomeGeeks
length of String = 12
范例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：
String = India is Great
length of String = 14
