回答by Clyde
Convert.ToDateTime(dr("CreateDate")).ToShortDate()
Convert.ToDateTime(dr("CreateDate")).ToShortDate()
See the MSDN docs for other functions available from the DateTime datatype, including custom formats available through the 'ToString' function.

Easy:
简单：
((DateTime)dr["CreateDate"]).ToString("MM/dd/yyyy")
// I would also check that it isn't dbnull before doing it though
// 我也会在做之前检查它是否不是 dbnull
if (! DBNull.Value.Equals(dr["CreateDate"])) // blah blah
回答by Geoff
Response.Write(DateTime.Parse(dr("CreateDate").ToString()).ToString("MM/dd/yyyy"))
