我把他改成這樣：strCommand = "select * from dbo.LilunInfo where 用戶名 = '" + m_UserName + "'";但是調試時還是一直都是顯示是本來的語句select * from dbo.JiaoXueInfo where 。。。。try{ string strCommand = "";strCommand = "select * from dbo.LilunInfo where 用戶名 = '" + m_UserName + "'";SqlDataAdapter dataCommand;DataSet set = new DataSet();dataCommand = SqlHelper.DataAdapter(BaseClass.ConnStr,CommandType.Text, strCommand);dataCommand.Fill(set, "srcAdminInfo");m_iRowNum1 = set.Tables[0].Rows.Count;m_iColumnNum1 = set.Tables[0].Columns.Count;if (m_iRowNum1 == 0){ return false; }m_strAllInfoJiaoxue = new string[m_iRowNum1 * m_iColumnNum1];for (int i = 0; i < m_iRowNum1; i++){for (int j = 0; j < m_iColumnNum1; j++){m_strAllInfoJiaoxue[j + i * m_iColumnNum1] = set.Tables[0].Rows[i][j].ToString();}}
