StringBuilder.MaxCapacity Property is used to get the maximum capacity of this instance.

Syntax: public int MaxCapacity { get; }

Property Value: It returns the maximum number of characters of type System.Int32 this instance can hold.

Note: The maximum capacity for this implementation is Int32.MaxValue. However, this value is implementation-specific and might be different in other or later implementations. You can explicitly set the maximum capacity of a StringBuilder object by calling the StringBuilder(Int32, Int32) constructor.


// C# program to demonstrate
// the MaxCapacity 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 str1 = 
         new StringBuilder("GeeksforGeeks");
        // printing the MaxCapacity of str1
        Console.WriteLine("Maximum Capacity of str1 is: " 
                                     + str1.MaxCapacity);
        // Create a StringBuilder object
        StringBuilder str2 = new StringBuilder();
        // printing the MaxCapacity of str2
        Console.WriteLine("Maximum Capacity of str2 is: " 
                                     + str2.MaxCapacity);


Maximum Capacity of str1 is: 2147483647
Maximum Capacity of str2 is: 2147483647
