本篇文章是對C#連接db2數據庫的方法進行了詳細的分析介紹，需要的朋友參考下

通過OLE DB for DB2驅動

string strSql = @"select phone_no from no_store where id<5";
            string strConn = "Provider=IBMDADB2;Data Source=數據庫名;UID=用戶名;PWD=密碼;";
            using (OleDbConnection conn = new OleDbConnection(strConn))
            {
                OleDbCommand cmd = new OleDbCommand(strSql, conn);
                try
                {
                    conn.Open();
                    OleDbDataAdapter adp = new OleDbDataAdapter(cmd);
                    DataSet ds = new DataSet();
                    adp.Fill(ds);
                    DataTable dt = ds.Tables[0];
                    if (dt != null)
                    {
                        for (int i = 0; i < dt.Rows.Count; i++)
                        {
                            Console.WriteLine("電話" + i + ":" + dt.Rows[i][0].ToString());
                        }
                    }
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
            }
            Console.Read();

通過IBM提供的IBM.data.DB2.DLL

復制代碼代碼如下:

string strSql = @"select phone_no from no_store where id<5";
            string strConn = "Database=數據庫名;UID=用戶名;PWD=密碼;";
            using (DB2Connection conn = new DB2Connection(strConn))
            {
                DB2Command cmd = new DB2Command(strSql, conn);
                try
                {
                    conn.Open();
                    DB2DataAdapter adp = new DB2DataAdapter(cmd);
                    DataSet ds = new DataSet();
                    adp.Fill(ds);
                    DataTable dt = ds.Tables[0];
                    if (dt != null)
                    {
                        for (int i = 0; i < dt.Rows.Count; i++)
                        {
                            Console.WriteLine("電話" + i + ":" + dt.Rows[i][0].ToString());
                        }
                    }
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
            }
            Console.Read();
