SqlConnection SqlCon = new SqlConnection("Data Source=(local);Database=  dbname;Integrated Security=SSPI;");

SqlDataReader SqlDr;

SqlCon.Open();
SqlCmd = SqlCon.CreateCommand();

SqlCmd.CommandText = "select * from Tablename";

SqlDr = SqlCmd.ExecuteReader();
SqlDr.Read();
int i=0;
while (i < SqlDr.FieldCount)
{ MessageBox.Show(SqlDr.GetDataTypeName(i)); i++;}'
