如何在C＃中查找StringBuilder的MaxCapacity

StringBuilder.MaxCapacity属性用于获取此实例的最大容量。

Syntax: public int MaxCapacity { get; }

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

注意：此实现的最大容量为Int32.MaxValue 。但是，此值是特定于实现的，并且在其他或更高版本的实现中可能会有所不同。您可以通过调用StringBuilder(Int32，Int32)构造函数来显式设置StringBuilder对象的最大容量。

例子：

// 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);
    }
}

输出：

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