C#读取Visual FoxPro(*.dbf)数据并使用SqlBulkCopy插入到SqlServer 2008 R2数据表中

公司数据库从32位的SqlServer 2005升级到64位的SqlServer 2008 R2后,无法再像原来通过Link Server连接VFP同步数据,因此考虑用代码程序从VFP数据库中读取所需数据然后再插入到SqlServer数据库中,下面贴出该C#代码以备忘或供有需要者参考。
        private void GetDataFromVFP()
        {
            OdbcConnection conn = null ;
            try
            {
                string strOdbcConn = @"Driver={Microsoft Visual FoxPro Driver};SourceType=DBF;SourceDB=D:/a/b;Exclusive=No;Collate=Machine;";
                string strInsertConn = @"User id=a;Password=b;Database=c;Server=d;Connect Timeout=50;Max Pool size=200;Min pool Size=5" ;
                conn = new OdbcConnection ();
                conn.ConnectionString = strOdbcConn;
                conn.Open();
                string strTableName = "" ;
                for (int i = -8; i < 0; i++)
                {
                    strTableName = "FOLIO" + DateTime .Today.AddDays(i).ToString("dd");
                    string sql = string .Format(@"select a,b,c from {0}", strTableName);
                    OdbcDataAdapter da = new OdbcDataAdapter(sql, conn);
                    DataTable dt = new DataTable();
                    da.Fill(dt);
                    SqlBulkCopy bulkCopy = new SqlBulkCopy(strInsertConn);
                    bulkCopy.BulkCopyTimeout = 1800000;
                    bulkCopy.DestinationTableName = "strTableName";
                    bulkCopy.WriteToServer(dt);
                }
            }
            catch
            { }
            finally
            {
                if (conn != null )
                {
                    conn.Close();
                }
            }
        }
