如果我尝试读取空的EXCEL单元格,则会收到System.com_object错误.我的代码是:

public static List<OrderPC> getFilters(string fileCheckout)
    {
        List<OrderPC> orderPCs = new List<OrderPC>();
        XLDoc sldoc = new XLDoc();

        string localPath = @"C:\Temp\PCs.xlsx";

        Microsoft.Office.Interop.Excel.Application oXL=null;
        Microsoft.Office.Interop.Excel.Workbook mWorkBook=null;
        Microsoft.Office.Interop.Excel.Worksheet mWSheet1=null;
        Microsoft.Office.Interop.Excel.Range xlRange=null;
        try

            oXL = new Microsoft.Office.Interop.Excel.Application();

            mWorkBook = oXL.Workbooks.Open(localPath);

            mWSheet1 = mWorkBook.Sheets[1];

            xlRange = mWSheet1.UsedRange;

            {

               int y = hl.Range.Column;

                int z = hl.Range.Row;

                string vFilter = mWSheet1.Cells[z, y + 1].Value2.Trim();

                if (vFilter.CompareTo("Weekly") == 0)
                {
                    String baseUri = "http://xxx.yyy.net?";
                    int followUpIndex = baseUri.Length;
