C＃中的StringBuilder.ToString方法

此方法用于将该实例的值转换为String。创建并初始化一个新的String对象，以从此StringBuilder对象获取字符序列，然后由ToString()返回String。 Object包含的对该序列的后续更改不会影响String的内容。

Syntax: public override string ToString ();

Return Value: This method returns the String representing the data contained by StringBuilder Object.

下面的程序说明了StringBuilder.ToString()方法：

范例1：

// C# program to demonstrate
// the ToString() Method
using System;
using System.Text;
  
class GFG {
  
    // Main Method
    public static void Main(String[] args)
    {
  
        // create a StringBuilder object
        // with a String pass as parameter
        StringBuilder str
          = new StringBuilder("GeeksForGeeks");
  
        // print string
        Console.WriteLine("String contains = "
                            + str.ToString());
    }
}

输出：

String contains = GeeksForGeeks

范例2：

// C# program to demonstrate
// the ToString() Method
using System;
using System.Text;
  
class GFG {
  
    // Main Method
    public static void Main(String[] args)
    {
  
        // create a StringBuilder object
        // with a String pass as parameter
        StringBuilder str = 
             new StringBuilder("GeeksforGeeks Contribute");
  
              
                  
        // print string
        Console.WriteLine("String contains = "
                          + str.ToString());
    }
}

输出：

String contains = GeeksforGeeks Contribute
