How to create the StringBuilder in C#
StringBuilder() constructor is used to initialize a new instance of the StringBuilder class which will be empty and will have the default initial capacity. StringBuilder is used to represent a mutable string of characters. Mutable means the string which can be changed. So String objects are immutable but StringBuilder is the mutable string type. It will not create a new modified instance of the current string object but do the modifications in the existing string object.
Syntax:
public StringBuilder ();
Example:
// C# Program to illustrate how // to create a StringBuilder using System; using System.Text; using System.Collections; class Geeks { // Main Method public static void Main(String[] args) { // sb is the StringBuilder object // StringBuilder() is the constructor // used to initializes a new // instance of the StringBuilder class StringBuilder sb = new StringBuilder(); // Capacity property is used to get // maximum number of characters that // can be contained in the memory // allocated by the current instance Console.WriteLine(sb.Capacity); } } |

Output:
16
Here 16 is the default capacity.
Note:
- Using this constructor will set the string value of the current instance to String.Empty.
- Capacity is set to the implementation-specific default capacity. Here it is 16.
