读取EXECL文件内容，可以支持分布

    private DataSet InExecl()
    {
        //string filename = get.filenames;
        //string filename =get.filenames ;
        string filename = Label23.Text;
        DataSet ds = new DataSet();
        string connStr = "Provider=Microsoft.Ace.OleDb.12.0;Data Source=" + Server.MapPath("up_product_store" + "\\" + filename) + "; Extended Properties=Excel 8.0;";
        OleDbConnection myConn = new OleDbConnection(connStr);
        myConn.Open();
        DataTable dt = myConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
        string tableNamess = dt.Rows[0][2].ToString().Trim();
        string strSQL = " SELECT * from [" + tableNamess + "] ";
        OleDbDataAdapter myCommand = new OleDbDataAdapter(strSQL, myConn);
        DataSet myDataSet = new DataSet();
        myCommand.Fill(myDataSet, tableNamess);
        myConn.Close();
        //myConn.Dispose();
        myConn.Dispose();
        myCommand.Dispose();
        return myDataSet;
    }
