如何与"dd/MM/yyyy"格式的日期进行比较 [英] how to compare to dates which are in 'dd/MM/yyyy' format

问题描述

大家好，

我想使用C#
比较asp.net中的日期
我的代码是这样的..

Hi All,

I want to compare the dates in asp.net using C#

my code is like this..

DateTime FromDate = Convert.ToDateTime(txtFromDate.Text);
DateTime ToDate = Convert.ToDateTime(txtToDate.Text);

 if (FromDate <= ToDate )
  {
    ------
  }

错误:无法将字符串识别为有效的DateTime.

通过使用"MM/dd/yyyy"格式，我们可以获得结果.但是，我的日期格式为"dd/MM/yyyy".
谁能帮我这个忙..

在此先感谢

error: String was not recognized as a valid DateTime.

by using ''MM/dd/yyyy'' format we can get the result. But, my date format is in ''dd/MM/yyyy''.
can any one help me for this..

thanks in advance

推荐答案

使用 DateTime.Compare() [ ^ ]
这是示例代码.

Use DateTime.Compare()[^]
Here is a sample code.

string strFromDate = "26/03/2012";
string strToDate = "26/04/2012";

DateTime FromDate = DateTime.ParseExact(strFromDate, "dd/MM/yyyy",null);
DateTime ToDate = DateTime.ParseExact(strToDate, "dd/MM/yyyy", null);

int result = DateTime.Compare(FromDate, ToDate);

if (result < 0)
{
    //from date is less than to date

}
