如何从 sql lite 数据库的列中向 datagridview 添加日期？

Question

When I use this C# code:

dataGridView2.Columns["sql_col_name"].DefaultCellStyle.Format = "YYYY-MM-DD HH:MM:SS.SSS" ,

the datagridview cell written in it is not the date but "YYYY-MM-DD HH:MM:SS.SSS"

where's the error??

Answer 1

Try to set column's DataType to DateTime . The default DataType is set to string.

Are you sure that the format "YYYY-MM-DD HH:MM:SS.SSS" is correct? Maybe you mean "yyyy-MM-dd HH:MM:ss.fff" ?

dataGridView2.Columns["sql_col_name"].DataType = typeof(DateTime);
dataGridView2.Columns["sql_col_name"].DefaultCellStyle.Format = "yyyy-MM-dd HH:MM:ss.fff";
