问题描述

推荐答案

1。首先，使用tryparse检查日期字符串是否有效;

2.指定所需的日期格式;

3.然后可以进行转换。

1. First, check that the date string is a valid one using tryparse;
2. Specify the desired date format;
3. then can do the conversion.

using System;

public class Program
{
    public static void Main()
    {
          // change 2/22/2014 5:08:46 PM to 2014-02-22.
          string dateString = "2/22/2014 5:08:46 PM";

          Console.WriteLine("The original string is {0}", dateString);

          DateTime dt;

          if (DateTime.TryParse(dateString, out dt))
          {
               string format = "yyyy-MM-dd";
               Console.WriteLine(dt.ToString(format));
          }
          else
          {
              Console.WriteLine("Not a valid datetime");
          }
    }
}

您将字符串传递给 string.Format 方法。

FullDate 变量必须是 DateTime 对象。

It's beacuase you're passing string to string.Format method.
FullDate variable must be DateTime object.

DateTime Fulldate = Request["msgDate"]; //"3/17/2014 10:32:35 AM"
string SDate = string.Format("{0:yyyy-mm-dd}", Fulldate);
