This paper summarizes the commonly used DateTime date type formatting display methods, for the convenience of readers in the use of reference 1. The details are as follows:

1. Date formatting method during binding:

<ASP:BOUNDCOLUMN DATAFIELD= "JoinTime " DATAFORMATSTRING= "{0:yyyy-MM-dd} " >
<ITEMSTYLE WIDTH= "18% " > </ITEMSTYLE >
</ASP:BOUNDCOLUMN >

2. Data controls such as DataGrid/DataList, etc.

e.Item.Cell[0].Text = Convert.ToDateTime(e.Item.Cell[0].Text).ToShortDateString();

3. Use String class to convert date display format:

String.Format( "yyyy-MM-dd ",yourDateTime);

4. Use Convert method to convert date display format:

Convert.ToDateTime("2005-8-23").ToString("yyMMdd",System.Globalization.DateTimeFormatInfo.InvariantInfo); // Support traditional database

5. Directly convert date display format with ToString method:

DateTime.Now.ToString("yyyy/MM/dd hh:mm:ss")

Or:

DateTime.Now.ToString("yyyyMMddhhmmss");

6. Only show the year and year

DataBinder.Eval(Container.DataItem,"starttime","{0:yyyy-M}")

7. Display all parts of the time, including: minutes and seconds of year, month and day

<asp:BoundColumn DataField=" Payment time " HeaderText=" Payment time " DataFormatString="{0:yyyy-MM-dd HH24:mm:ss}">
</asp:BoundColumn>

8. Format the time to read from the database

Convert.ToDateTime(dr["MT_ENDate"]).ToShortDateString();
