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 odbcReader= 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）
