Solution 2

Change the DataType of the date column in SQL to datetime and leave the dateTimePicker1.Value to default settings

use:

"SELECT * FROM Table WHERE Date= '" + Convert.ToDateTime(dateTimePicker1.Value)' ";

Solution 1

Use a parametrised query instead:

C#

SqlDataAdapter com = new SqlDataAdapter("SELECT * FROM Farmers WHERE Date=@DT", con);
com..SelectCommand.Parameters.AddWithValue("@DT", dateTimePicker1.Value.Date);
DataSet ds = new DataSet("Farmers");
con.Open();
com.Fill(ds);
con.Close();
