.NET通过ODBC 连接 SQL SERVER

 string constr = "driver={sql server};database=" + databaseNAME+ ";server=" + 服务器地址 + ";"//SQL SERVER驱动
  constr += "UID=invuser;PWD=1;"

OdbcCommand cmd_s = new OdbcCommand(sSQL, conn_odbc); 
                        OdbcDataReader reader_s = cmd_s.ExecuteReader();//执行查询
                        int iCZ = 0;
                        while (reader_s.Read())
                        {
                            JLBH_OUT.Add(data.iJLBH);
                            iCZ=1;
                        }
                        reader_s.Close();

sSQL = " insert into dbo(操作员名称,导出日期) values ";
string stmp = "(";
stmp += "‘" + sDJRMC + "‘,getdate()";
stmp += ")";
sSQL += stmp;
OdbcCommand cmd_in = new OdbcCommand(sSQL, conn_odbc);
int iInsert = cmd_in.ExecuteNonQuery(); //执行插入
conn_odbc.Close();

OdbcConnection cn;
       OdbcCommand cmd;
       string MyString;
       MyString="Select * from dbo";
       cn= new OdbcConnection("dsn=myDSN;UID=invuser;PWD=1;");//通过DSN
       cmd=new OdbcCommand(MyString,cn);
       cn.Open();
       MessageBox.Show("Connected");
       cn.Close();
