C#连接DB2数据库的方法和代码

项目中遇到的。net（ C#） 连接DB2问题，解决了，和大家分享一下。

    下面的程序是同不Sql2005中的表与DB2中的表

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.Odbc; using System.Data.SqlClient; using System.Data; namespace DB2Import {     class Program     {         static void Main(string[] args)         {             OdbcConnection DB2Connection = new OdbcConnection("Dsn=DataSourceName;uid=UserName;pwd=mismidas");//创建DB2的数据源连接 //这里是用数据源连接的           //DataSourceName 数据源名称          //UserName 用户名          //pwd 用户口令             //OdbcCommand             SqlConnection conSql = new SqlConnection("Data Source=oadatabase\\userdb2005;Initial Catalog=GongChengGuanLi;Persist Security Info=True;User ID=sqlUserName;Password=SqlPassword");//Sql2005的数据库连接             DB2Connection.Open();//打开DB2的数据源连接             SqlDataAdapter ZDAdapter = new SqlDataAdapter(new SqlCommand("Select * from SCD_GXDY_XGJL", conSql));             SqlCommandBuilder myCommandBuilder = new SqlCommandBuilder(ZDAdapter);             DataSet ZDDataSet = new DataSet();             ZDAdapter.Fill(ZDDataSet, "SCD_GXDY_XGJL");             for (int i = 0; i < ZDDataSet.Tables["SCD_GXDY_XGJL"].Rows.Count; i++)             {                 Console.WriteLine("importing "+i+" .....");                 DataRow row = ZDDataSet.Tables["SCD_GXDY_XGJL"].Rows[i];                 int KHDM = 0;                 try                 {                     KHDM = int.Parse("" + row["KHDM"]);                 }                 catch (Exception paresException)                 {                     KHDM = 0;                 }                 //KHDM                 if ("" + row["KHDM"] != "" && KHDM!=0)                 {                     OdbcCommand cmdSelect = new OdbcCommand("Select CCUST,CNME,CTYPE,CLOC,CMDPFX from V6tstF.RCM where CCUST=" +KHDM+ "", DB2Connection);                    OdbcDataReader dbcReader= cmdSelect.ExecuteReader();                    if (odbcReader.Read())//从DB2中读取数据                    {                        row["CNME"] = ""+odbcReader["CNME"];                        row["CTYPE"] = "" + odbcReader["CTYPE"];                        row["CLOC"] = "" + odbcReader["CLOC"];                        row["CMDPFX"] = "" + odbcReader["CMDPFX"];                    }                    odbcReader.Close();                 }             }             Console.WriteLine("Updating ....");             ZDAdapter.Update(ZDDataSet, "SCD_GXDY_XGJL");             Console.WriteLine("Commplete!");             Console.WriteLine("Press any Key to Exit!");             Console.Read();         }     } }

    但可能有朋友要问了，DB2的数据源是怎么建立的，安装IBM DB2 RUN-Time Client.

    然后运行“從屬站架構輔助程式”来添加数据源。（剩下就是下一步了啊）
