我正在使用 c# 中的 Microsoft.Office.Interop.Excel 库设计一个小程序。我的程序读取excel文件（名称为1.xlss，2.xlsx等）并制作一个新的excel文件，然后将所有excel文件的数据复制到一个行间距的新excel文件中。我还设置了单元格的某些属性，如边框、字体、背景颜色等。

第一个 excel 文件（1.xls）一切都很好，但在第 2、第 3 等情况下，它没有设置单元格的边框属性。这是我的代码

// data member initialization for reading the sheet
        Excel.Application app;
        Excel.Workbook workbook;
        Excel.Worksheet worksheet;
        Excel.Range range;

        // data member initialization for writing sheet
        Excel.Application finalApp;
        Excel.Workbook finalWorkBook;
        Excel.Worksheet finalWorkSheet;

        String path = this.textBox1.Text;
        String numberOfFiles = (String)this.comboBox1.SelectedItem;
        int count = 1;
        int row = 1, col = 1;
        try
        {
            // Object creation for the final sheet
            finalApp = new Excel.ApplicationClass();
            finalApp.Visible = true;
            finalWorkBook = finalApp.Workbooks.Add(1);
            finalWorkSheet = (Excel.Worksheet)finalWorkBook.Sheets[1];


            // opening a excel file
            app = new Excel.ApplicationClass();
            Excel.Borders b=null;
            Excel.Borders fb = null;
            try
            {
                for (int k = 0; k < Int32.Parse(numberOfFiles); k++)
                {
                    fullPath = @path + @"\" + count + ".xlsx";
                    workbook = app.Workbooks.Open(fullPath, Missing.Value, Missing.Value,
                        Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value
                        , Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value,
                        Missing.Value);
                    worksheet = (Excel.Worksheet)workbook.Sheets.get_Item(1);
                    range = worksheet.UsedRange;
                    int cnum1 = range.Columns.Count;
                    int rnum1 = range.Rows.Count;
                    int i, j;
                    for (i = 1; i <= rnum1; i++)
                    {
                        for (j = 1; j <= cnum1; j++)
                        {
                            if ((range.Cells[i, j] as Excel.Range).Value2 != null)
                            {
                                string value1 = (range.Cells[i, j] as Excel.Range).Value2.ToString();
                                finalWorkSheet.Cells[row, col] = value1;
                                b= (Excel.Borders)(range.Cells[i, j] as Excel.Range).Borders;
                                //MessageBox.Show(b.Weight.ToString());
                                fb=(finalWorkSheet.Cells[i, j] as Excel.Range).Borders;
                                fb[Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeBottom].Weight= b[Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeBottom].Weight;

                                //fb.Color = b.Color;
                                //(finalWorkSheet.Cells[i, j] as Excel.Range).BorderAround(b.LineStyle,(Excel.XlBorderWeight)b.Weight,

                    count++;
                    row++;
                    col = 1;

            }
            catch (FileNotFoundException fnfe)
            {
                MessageBox.Show("Error while opening the file "+fullPath);
            }
            //finalWorkBook.Close(true,false,Missing.Value);
        }
        catch (Exception ex)
        {
            MessageBox.Show(@"Some Error has occurred.Please check the path Correctly
            whether it's correct or not");
        }
    }

任何帮助，将不胜感激。

fb=(finalWorkSheet.Cells[i, j] as Excel.Range).Borders;

应该

fb=(finalWorkSheet.Cells[row, col] as Excel.Range).Borders;
