StringBuilder.EnsureCapacity() Method in C#
The StringBuilder.EnsureCapacity() method in C# is used to ensure that the capacity of this instance of StringBuilder is at least the specified value.
Syntax
The syntax is as follows −
public int EnsureCapacity (int capacity);
Above, the parameter capacity is the minimum capacity to ensure.
Example
Let us now see an example −
using System;
using System.Text;
public class Demo{
public static void Main(){
StringBuilder strBuilder = new StringBuilder("jhbjhb");
Console.WriteLine("String = "+strBuilder);
Console.WriteLine("StringBuilder capacity= "+strBuilder.Capacity);
strBuilder.EnsureCapacity(20);
Console.WriteLine("StringBuilder capacity= "+strBuilder.Capacity);
char[] arr = new char[5] {'a', 'b', 'c', 'd', 'e'};
strBuilder.CopyTo(1, arr, 1, 3);
Console.WriteLine("
Copied String in char array...");
Console.WriteLine(arr);
}
}Output
This will produce the following output −
String = jhbjhb StringBuilder capacity= 16 StringBuilder capacity= 20 Copied String in char array... ahbje
Example
Let us now see another example −
using System;
using System.Text;
public class Demo{
public static void Main(){
StringBuilder strBuilder = new StringBuilder("Katie");
Console.WriteLine("String = "+strBuilder);
Console.WriteLine("
StringBuilder capacity = "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
strBuilder.EnsureCapacity(35);
Console.WriteLine("
StringBuilder capacity= "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
strBuilder.EnsureCapacity(0);
strBuilder.Length = 0;
Console.WriteLine("
StringBuilder capacity= "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
}
}Output
This will produce the following output −
String = Katie StringBuilder capacity = 16 StringBuilder length = 5 StringBuilder capacity= 35 StringBuilder length = 5 StringBuilder capacity= 35 StringBuilder length = 0
