How to find the length of the StringBuilder in C#

StringBuilder.Length Property is used to get or set the length of the current StringBuilder object.

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.

Below programs illustrate the use of the above-discussed property:

// 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);
    }
}
