日期时间转换C# [英] DateTime Conversion C#

问题描述

我在转换由用户以''MM-dd-yyyy''格式输入的日期时遇到问题.
我用了

Hi,

I have a problem while converting date which is entered by user in format of ''MM-dd-yyyy''.
I used

dt = convert.todatetime(txt_date.text);

但由于无法将String识别为有效的DateTime而显示错误.

例如.我想使用convert.todatetime将日期"06-16-2011"转换为日期时间.

but it shows error as String was not recognized as a valid DateTime.

Eg. I want to convert date "06-16-2011" as datetime using convert.todatetime.

推荐答案

try
 {

  CultureInfo format_dt = new CultureInfo(en-US);
  dt = DateTime.ParseExact(txt_date.Text, "MM-dd-yyyy", format_dt)
 }
 catch (FormatException)
 {
  Messagebox.show(FormatException.show);
}

这是可行的

This is working

如果您想将字符串转换为日期时间，并且它将始终采用特定格式，而不是运行PC的文化，然后使用 DateTime.ParseExact [

If you want to convert a string to a date time, and it is going to always be in a specific format, rather than the culture of the PC it is running on, then use the DateTime.ParseExact[^] Method:

dt = Date.ParseExact("05-16-2011","dd-MM-yyyy", CultureInfo.InvariantCulture)

dt = convert.todatetime(txt_date.text.ToString("MM-dd-yyyy"));
