C#連接sybase

1、Ado.Net連接：

         1、安裝Sybase1252客戶端，選擇自定義案裝，將ado.Net選上。

         2、創建c#項目，添加引用Sybase.Data.AseClIEnt.dll到項目中。此dll在Sybase的安裝目錄下面。

         3、程序的前部寫上using Sybase.Data.AseClIEnt;

         3、在一個按鈕事件中寫入：

                   try

            {

                AseConnection conn = new AseConnection("Data Source='192.168.1.26';Port='5000';UID='sa';PWD='';Database='test';");

                AseCommand comm = new AseCommand("select * from student", conn);

                conn.Open();

                AseDataReader dr = comm.ExecuteReader();

                 string str = "";

                while (dr.Read())

                {

                    str = str + dr.GetString(0);

                }

                this.label1.Text = str;

                conn.Close();

                dr.Close();

            }

           catch (Exception ex)

            {

                MessageBox.Show(ex.Message);

            }

2、Odbc連接：

1、建立odbc數據源命名為QQ，driver選擇Sybase ASE ODBC Driver

2、建立c#程序。

3、寫上using System.Data.Odbc;

4、在一個按鈕事件中寫入：

         try

            {

                OdbcConnection conn = new OdbcConnection("DSN=QQ;UID=sa;Pwd=");

                OdbcCommand comm = new OdbcCommand("select * from student", conn);

                conn.Open();

                OdbcDataReader dr = comm.ExecuteReader();

                string str = "";

                while (dr.Read())

                {

                    str = str + dr.GetString(0);

                }

                this.label1.Text = str;

                conn.Close();

                dr.Close();

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message);            }
