Hi,

I have a requirement where i need to changes the date format from dd/mm/yyyy to mm/dd/yyyy and vice versa.

I have a problem with dates having 12/13/2006 or 13/12/2007. That means there is a problem of converting 12 and 13. Can anyone please help me on this how to resolve?

dataGridView1.Rows[rowindex].Cells[index].Value = Convert.ToDateTime(Column[i]).ToString(StaticVar.DateFormat);

What I have tried:

I tried changing the format in multiple times but didn
t worked.

推荐答案

DateTime dt = DateTime.ParseExact("13/12/2006", "dd/MM/yyyy", CultureInfo.InvariantCulture);
string dtNew = dt.ToString("MM/dd/yyyy", CultureInfo.InvariantCulture);

对于问题"12/13"或"13/12"，您必须知道您现在所处的文化区域.这样您就可以以正确的方式进行转换.如果您想捕获异常，那也是不可能的，因为这两个日期都可以:1/2或2/1-> 1月2日或2月1日

For the problem "12/13" or "13/12", you must know, in what cultureinfo you are right now. So that you can convert it in the right way. If you want to catch exception, that is also not possible, because these 2 dates are OK : 1/2 or 2/1 -> Jan 2nd or Feb 1st
