StringBuilder.Clear Method is used to remove all the characters from the current StringBuilder instance.

Syntax:

public System.Text.StringBuilder Clear ();

It returns an StringBuilder object whose length will be zero.

Note:

Clear is a convenience method that is equivalent to setting the Length property of the current instance to 0 (zero).
Calling the Clear method does not modify the current instance’s Capacity or MaxCapacity property.

Example:

   // C# program to demonstrate 
// the Clear() Method 
using System; 
using System.Text; 
  
class GFG { 
  
    // Main Method 
    public static void Main(String[] args) 
    { 
        // Creating a StringBuilder object 
        StringBuilder sb1 = new StringBuilder("GeeksforGeeks"); 
  
        // printing the length of "GeeksforGeeks" 
        Console.WriteLine("The String is: {0} \nTotal characters -- {1}", 
                                             sb1.ToString(), sb1.Length); 
  
        // using the method 
        sb1.Clear(); 
  
        // printing the length of "GeeksforGeeks" 
        Console.WriteLine("The String is: {0} \nTotal characters -- {1}", 
                                             sb1.ToString(), sb1.Length); 
  
        sb1.Append("This  is C# Tutorials."); 
  
        // printing the length of "GeeksforGeeks" 
        Console.WriteLine("The String is: {0} \nTotal characters -- {1}", 
                                             sb1.ToString(), sb1.Length); 
    } 
} 
 
  

Output:

  The String is: GeeksforGeeks   Total characters -- 13  The String is:    Total characters -- 0  The String is: This  is C# Tutorials.   Total characters -- 22
