Answer 1

int numberOfRows = mySqlDataAdapter.Fill(myDataSet, "yourTableName");             DataTable tbl = myDataSet.Tables["yourTableName"];            int MaxStrLen= 0 ;
            int CurStrLen = 0 ;            for (int i = 0; i < numberOfRows; i++)
            {
                try
                {
  if (tbl.Rows[i]["name"]!=null)
                    CurStrLen = tbl.Rows[i]["name"].ToString().Trim().Lenght);
                  else 
                    continue ;                  if (MaxStrLen<CurStrLen)
                        MaxStrLen=CurStrLen;
                }
                catch
                {
                    MessageBox.Show("数据转换出错");
                    break ;
                }
             }
