循環使用Excel文件並使用C＃在單獨的文件中復制正確的范圍

Question

簡介：今天我決定使用C＃進行Excel自動化任務。 這可能是我第一次做這樣的事情，因此問題很多。

任務：差不多，這個想法如下 - 我在文件夾strPath有4個excel文件。 我必須循環遍歷所有這些文件並在同一文件夾中創建一個名為Report.xlsx的文件，其中包含這些文件中的信息。

我需要的信息是第9行下面的任何信息。因此，要復制的第一行是第10行。這就是為什么，我循環的第一個文件保存為Report，並且bMakeOnce值被更改。 在第一個文件循環並保存為As后，我開始進入else條件。 在那里，我找到XL文件的最后一行，我嘗試將范圍復制到sheetReport。

問題：

1. 首先 - 任何代碼改進的想法;

2. 每當我循環瀏覽文件時，我得到以下圖片，告訴我每個循環文件​​已經打開。

3. 有什么好主意如何更好地進行范圍復制？ 目前，我只是嘗試將復制的范圍放在每200 + n行，以避免一些混淆。

4. 知道為什么我在sheetReport中沒有得到任何東西，除了第一個文件？

我正在使用的代碼（最初，對於下面的當前goto Github）：

     using System;
     using System.Collections.Generic;

            string[] strFiles = Directory.GetFiles(strPath);

            int intFirstLine = 10;
            int intLastColumn = 50;

            Excel.Workbook wkbReport = null;
            string strWkbReportPath;
            int n = 0;

            foreach (string strFile in strFiles)

現在它以某種方式工作，產生我想要的東西：

using System;
using System.IO;
using Excel = Microsoft.Office.Interop.Excel;

class MainClass
{
    static void Main()
    {
        string strPath = Path.GetFullPath(Path.Combine(Directory.GetCurrentDirectory(), @"..\..\..\"));
        string[] strFiles = Directory.GetFiles(strPath);
        Excel.Application excel = null;
        bool bMakeOnce = true;
        string strReportName = "Report.xlsx";
        int intFirstLine = 10;
        int intLastColumn = 50;
        int lastRow;
        int lastRowReport;
        int intTotalRows;

        Excel.Workbook wkbReport = null;
        string strWkbReportPath;
        int n = 0;

        excel = new Excel.Application();
        excel.Visible = true;

        foreach (string strFile in strFiles)
        {
            if (strFile.Contains(strReportName))
            {
                Console.WriteLine(strReportName + " is deleted.");
                File.Delete(strFile);
            }
        }

        foreach (string strFile in strFiles)
        {
            if (strFile.Contains(strReportName))
            {
                continue;
            }
            Console.WriteLine(strFile);
            Excel.Workbook wkb = null;
            Excel.Worksheet sheet = null;
            Excel.Worksheet sheetReport = null;
            Excel.Range rngLastReport = null;

            wkb = Open(excel, strFile);
            if (bMakeOnce)
            {
                bMakeOnce = false;
                strWkbReportPath = wkb.Path + "\\" + strReportName;
                wkb.SaveAs(strWkbReportPath);
                wkb.Close();
                wkbReport = Open(excel, strWkbReportPath);
            }
            else
            {   
                sheetReport = wkbReport.Worksheets[1];
                sheet = wkb.Worksheets[1];

                //lastRow = sheet.Cells[1, 3].get_End(Excel.XlDirection.xlUp).Row;

                intTotalRows = sheet.Rows.Count;
                lastRow = sheet.Cells[intTotalRows, 1].End(Excel.XlDirection.xlUp).Row;
                lastRowReport = sheetReport.Cells[intTotalRows, 1].End(Excel.XlDirection.xlUp).Row;

                //lastRowReport = sheetReport.Cells[intTotalRows, 1].get_End(Excel.XlDirection.xlUp).Row;
                //lastRowReport = sheetReport.Cells[intTotalRows, intTotalRows.End[Excel.XlDirection.xlUp]].Row;
                n++;

                rngToCopy = sheet.Range[sheet.Cells[intFirstLine,1],sheet.Cells[lastRow, intLastColumn]];
                int size = rngToCopy.Rows.Count;
                rngLastReport = sheetReport.Range[sheetReport.Cells[lastRowReport+1, 1], sheetReport.Cells[lastRowReport + 1+size, intLastColumn]];

                rngToCopy.Copy(rngLastReport);
                wkb.Close(false);
            }
        }
        wkbReport.Close(true);
        excel.Quit();
        Console.WriteLine("Finished!");
    }

    public static Excel.Workbook Open(Excel.Application excelInstance, string fileName, bool readOnly = false, bool editable = true, bool updateLinks = true)
    {
        Excel.Workbook book = excelInstance.Workbooks.Open(
            fileName, updateLinks, readOnly,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, editable, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing);
        return book;
    }
    //public static Excel.Workbook OpenBook(Excel.Application excelInstance, string fileName, bool readOnly = false, bool editable = true, bool updateLinks = true)
    //{
    //    Excel.Workbook book = excelInstance.Workbooks.Open(

    //    return book;
    //}

}
