How to find the length of the StringBuilder in C#?

To find the length of the StringBuilder in C#, the code is as follows −

Example

 Live Demo

using System;
using System.Text;
public class Demo {
   public static void Main(String[] args) {
      StringBuilder strBuilder1 = new StringBuilder("Amy");
      StringBuilder strBuilder2 = new StringBuilder("Katie");
      StringBuilder strBuilder3 = new StringBuilder();
      StringBuilder strBuilder4 = new StringBuilder(5);
      strBuilder2 = strBuilder3;
      Console.WriteLine("Is StringBuilder3 equal to StringBuilder2? = "+strBuilder3.Equals(strBuilder2));
      Console.WriteLine("StringBuider1 capacity = "+strBuilder1.Capacity);
      Console.WriteLine("StringBuider1 maximum capacity = "+strBuilder1.MaxCapacity);
      Console.WriteLine("StringBuider1 length = "+strBuilder1.Length);      
      Console.WriteLine("StringBuider2 capacity = "+strBuilder2.Capacity);
      Console.WriteLine("StringBuider2 maximum capacity = "+strBuilder2.MaxCapacity);
      Console.WriteLine("StringBuider2 length = "+strBuilder2.Length);
      Console.WriteLine("StringBuider3 capacity = "+strBuilder3.Capacity);
      Console.WriteLine("StringBuider3 maximum capacity = "+strBuilder3.MaxCapacity);
      Console.WriteLine("StringBuider3 length = "+strBuilder3.Length);
      Console.WriteLine("StringBuider4 capacity = "+strBuilder4.Capacity);
      Console.WriteLine("StringBuider4 maximum capacity = "+strBuilder4.MaxCapacity);
      Console.WriteLine("StringBuider4 length = "+strBuilder4.Length);
   }
}

Output

This will produce the following output −

Is StringBuilder3 equal to StringBuilder2? = True
StringBuider1 capacity = 16
StringBuider1 maximum capacity = 2147483647
StringBuider1 length = 3
StringBuider2 capacity = 16
StringBuider2 maximum capacity = 2147483647
StringBuider2 length = 0
StringBuider3 capacity = 16
StringBuider3 maximum capacity = 2147483647
StringBuider3 length = 0
StringBuider4 capacity = 5
StringBuider4 maximum capacity = 2147483647
StringBuider4 length = 0

Example

Let us see another example −

 Live Demo

using System;
using System.Text;
public class Demo {
   public static void Main(String[] args) {
      StringBuilder strBuilder1 = new StringBuilder("hbjhbkjhbm");
      StringBuilder strBuilder2 = new StringBuilder("TomHanks");
      StringBuilder strBuilder3 = new StringBuilder();
      Console.WriteLine("Capacity of StringBuilder1 = "+strBuilder1.Capacity);
      Console.WriteLine("Length of StringBuilder1 = "+strBuilder1.Length);
      Console.WriteLine("
Capacity of StringBuilder2 = "+strBuilder2.Capacity);
      Console.WriteLine("Length of StringBuilder2 = "+strBuilder2.Length);
      Console.WriteLine("
Capacity of StringBuilder3 = "+strBuilder3.Capacity);
      Console.WriteLine("Length of StringBuilder3 = "+strBuilder3.Length);
   }
}

Output

This will produce the following output −

Capacity of StringBuilder1 = 16
Length of StringBuilder1 = 10
Capacity of StringBuilder2 = 16
Length of StringBuilder2 = 8
Capacity of StringBuilder3 = 16
Length of StringBuilder3 = 0
