C＃中的DateTime.ToShortDateString()方法

此方法用于将当前DateTime对象的值转换为其等效的短日期字符串表示形式。

Syntax: public string ToShortDateString ();

Return Value: This method returns a string that contains the short date string representation of the current DateTime object.

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

范例1：

// C# program to demonstrate the
// DateTime.ToShortDateString()
// Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // creating object of DateTime
            DateTime date = new DateTime(2010, 1,
                                    1, 4, 0, 15);
  
            // getting ShortTime from DateTime
            // using ToShortDateString() method;
            string value = date.ToShortDateString();
  
            // Display the ShortTime
            Console.WriteLine("date is {0}", value);
        }
  
        catch (FormatException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

输出：

date is 01/01/2010

范例2：

// C# program to demonstrate the
// DateTime.ToShortDateString()
// Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // calling check() method
        check(new DateTime(2010, 1, 3, 4, 0, 15));
  
        check(new DateTime(2010, 1, 5, 4, 0, 15));
  
        check(new DateTime(2010, 1, 5, 4, 0, 15));
    }
  
    public static void check(DateTime date)
    {
  
        // getting ShortTime from DateTime
        // using ToShortDateString() method;
        string value = date.ToShortDateString();
  
        // Display the date
        Console.WriteLine("date of {0} is "+
                        "{1}", date, value);
    }
}

输出：

date of 01/03/2010 04:00:15 is 01/03/2010
date of 01/05/2010 04:00:15 is 01/05/2010
date of 01/05/2010 04:00:15 is 01/05/2010
