1.在服务器上安装Sybase客户端，配置Dsedit，如下图：

2.配置ODBC的系统DSN，如下图：

3.源代码示例：

以下是代码片段：

  public XmlDocument RiverXml() //Log库
  {
   //定义LOG库的ODBC数据源
   string strODBCConnection_LogDB = "Driver={SYBASE SYSTEM 11};Srvr=jdtmdb;Uid=sa;Pwd=;DB=logdb"; // logdb 是数据库名称

   OdbcConnection oLogConn;
   OdbcCommand oLogCmd;
   XmlDocument doc;
   XmlTextWriter xtw;
   string lcHtml;

   string strDbReturnString;
   OdbcDataReader myLogDataReader = null;
   string STCD;
   string STNA = "";
   string strSql;
   strSql = "select * from TV_RIVER_T order by YMDHM desc";
   
   //ST_DAM_R
   strDbReturnString = "";
   oLogConn = new OdbcConnection(strODBCConnection_LogDB);
   oLogCmd = new OdbcCommand(strSql, oLogConn);
   oLogConn.Open();
   myLogDataReader = oLogCmd.ExecuteReader(CommandBehavior.CloseConnection);
   while (myLogDataReader.Read())
   {
    STCD = myLogDataReader["STCD"].ToString();
    if (STCD == "53049") STNA = "邵伯水位站";
    if (STCD == "53071") STNA = "兴化";
    strDbReturnString +=
     "<Rows>" +
      "<Cols>" + STCD + "</Cols>" +
      "<Cols>" + STNA + "</Cols>" +
      "<Cols>" + DateTime.Parse(myLogDataReader["YMDHM"].ToString()).ToString("yyyy-MM-dd HH:mm") + "</Cols>" +
      "<Cols>" + myLogDataReader["ZR"].ToString() + "</Cols>" +
      "<Cols>" + myLogDataReader["Q"].ToString() + "</Cols>" +
      "<Cols>" + myLogDataReader["XSA"].ToString() + "</Cols>" +
      "<Cols>" + myLogDataReader["ZRTEND"].ToString() + "</Cols>" +
      "<Cols>" + myLogDataReader["QMES"].ToString() + "</Cols>" +
      "</Rows>";
    STNA = "";
   }
   myLogDataReader.Close();
   oLogConn.Close();

   // .... 以下部分略...
