再次求教DTS导入的问题

我在利用DTS导入SQL时，程序不出现错误，但是没有将需要的数据导入到sql中，大家帮我看看：
代码如下：
Button代码：

    string strdespath="bsee";
            string strsourcepath ="c:\\File\\abc.XLS";
            string tablename="OTHER_MainPTJob";            
            string strsql="select  id  from [bsee].[dbo].[OTHER_MainPTJob]";
            AppExportData tryclass=new AppExportData(strsourcepath,strdespath,tablename,strsql);
            tryclass.ExportData();        

导入类：

    public class AppExportData
        {
            //DTS包对象
            public DTS.Package2Class ObjDTS;
            //源文件路径
            private string strSourceFilePath;
