如何在c＃中将文本框日期更改为ddmmyyy格式 [英] how to change the textbox date to ddmmyyy format in c#

问题描述

我想验证c中的textboxdate和gridview行日期＃



我的代码如下

i want to validate the textboxdate and gridview row date in c#

My code as follows

DateTime selectedfromdate = Convert.ToDateTime(Txtfromdate.SelectedDateValue);
for (int i = 0; i < GvSch.Rows.Count; i++)
{
  if (selectedfromdate == Convert.ToDateTime(rows.Cells[0].Text.ToString().Trim()))
  {
    Lblerr.Text = "selected date and excel sheet should be same";
    return;
  }
}

当我调试和检查时

在selectfrom日期值是9月2日上午12:00:00

rows.cells [0] .text.tostring（），trim（）值是1-Sep-14



i想要改变所选日期的格式是1-sep-14格式。



与gridview日期格式相同1-Sep -14。



我怎样才能在asp.net中使用c＃。

When i debug and check
In selectedfrom date value is 9/2/2014 12:00:00 AM
rows.cells[0].text.tostring(),trim() value is 1-Sep-14

i want to change the format of selectedfrom date is 1-sep-14 format.

like same as gridview date format 1-Sep-14.

for that how can i do in asp.net using c#.

推荐答案

DateTime selectedfromdate = Convert.ToDateTime(Txtfromdate.SelectedDateValue).ToString("dd-MMM-yy");

for (int i = 0; i < GvSch.Rows.Count; i++)
{
  if (selectedfromdate == Convert.ToDateTime(rows.Cells[0].Text.ToString("dd-MMM-yy").Trim()))
  {
    //do your code here.

  }
}

DateTime selectedfromdate = Convert.ToDateTime(Txtfromdate.SelectedDateValue).ToString("dd-MMM-yyyy");

for (int i = 0; i < GvSch.Rows.Count; i++)
{
  if (selectedfromdate == Convert.ToDateTime(rows.Cells[0].Text.ToString().Trim()))
  {
    Lblerr.Text = "selected date and excel sheet should be same";
    return;
  }
}
