datetime搜索方法 [英] datetime methods for search

问题描述

if (String.IsNullOrEmpty(tb_eventDateFrom.Text))
{
    msg1 = "Date From is empty, please re-select!";
    lb_msg.Text = msg1;
}
else
{
    var enCulture = new System.Globalization.CultureInfo("en-us");
    DateTime dateFrom = DateTime.ParseExact(tb_DateFrom.Text,"dd/M/yyyy",enCulture);
}

我正在做一个搜索功能所以这个方法对我不起作用，你怎么用其他方法自由搜索。

I am doing a search function so this method would not work for me, how would you search freely by using another method.

推荐答案

if (String.IsNullOrEmpty(tb_eventDateFrom.Text))
{
    msg1 = "Date From is empty, please re-select!";
    lb_msg.Text = msg1;
     return; // if any single value is not valid it will return...
}
else
{
    var enCulture = new System.Globalization.CultureInfo("en-us");
    DateTime dateFrom = DateTime.ParseExact(tb_DateFrom.Text,"dd/MM/yyyy",enCulture);
}

如果你改变这个，你可能会得到更好的结果：

You might get a better result if you change this:

DateTime dateFrom = DateTime.ParseExact(tb_DateFrom.Text, "dd/M/yyyy", enCulture);

对此：

To this:

DateTime dateFrom = DateTime.ParseExact(tb_DateFrom.Text, "dd/MM/yyyy", enCulture);

但是...你展示的代码确实如此根本没有搜索，所以我们无法以任何方式回答你的问题。

But...the code you show does not searching at all, so we can't answer your question in any otehr way.
