下面的程序说明了DateTime.ToLongDateString()方法的用法：

范例1：

// C# program to demonstrate the
// DateTime.ToLongDateString()
// Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // creating object of DateTime
        DateTime date = new DateTime(2011, 1,
                                1, 4, 0, 15);
  
        // Converting the value of the 
        // current DateTime object to 
        // its equivalent long date 
        // string representation.
        // using ToLongDateString() method;
        string value = date.ToLongDateString();
  
        // Display the date
        Console.WriteLine("String representation"+
                        " of date is {0}", value);
    }
}

输出：

String representation of date is Saturday, 01 January 2011

范例2：

// C# program to demonstrate the

        // creating object of DateTime
        DateTime date = DateTime.Now;
  
        // Converting the value of the
        // current DateTime object to 
        // its equivalent long date 
        // string representation.
        // using ToLongDateString() method;
        string value = date.ToLongDateString();
  
        // Display the date
