设置文本框字段以接受输入作为日期格式 [英] Set textbox field to accept input as date format

问题描述

我可以知道如何设置文本框（例如.txt1）以接受日期格式（例如2014-05）。每次运行程序时都会自动出现 - ，输入2014后，光标会跳到 - 后面。我知道有DateTimePicker，但我的白痴团队领导坚持要做文本框的事情。任何帮助将不胜感激。



目前我有以下代码（使用DateTimePicker）：

Hi, may i know how can i set the textbox(eg. txt1) to accept date format(eg. 2014-05). The "-" would be automatically be there every time i run the program and after i have enter "2014", the cursor would jump to behind the "-". I know there is DateTimePicker but my idiot team leader insist me on doing the textbox thing. Any help would be appreciated thks.

Currently i have the following code(which is using DateTimePicker):

string dateFrom = perFromDate.Value.ToString("MMM-yyyy");
string dateTo = perToDate.Value.ToString("MMM-yyyy");

TimeSpan range = DateTime.Parse(dateTo).Subtract(DateTime.Parse(dateFrom));
int newRange = range.Days;

if (newRange > 365)
{
    MessageBox.Show("Date is out of range.", "Validation", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
