比較兩個Excel文件並將差異放入新表中

Question

我正在比較兩個像這樣的工作表：

一張紙比另一張紙新，可以刪除，添加或更新一行。

我的代碼來檢測兩者之間是否被刪除/添加了一行，這對我不起作用，這是我所擁有的：

Private Sub CompareSpreadsheets()
    Dim xlApp1 As Excel.Application = New Microsoft.Office.Interop.Excel.Application()
    Dim xlApp2 As Excel.Application = New Microsoft.Office.Interop.Excel.Application()
    Dim xlApp3 As Excel.Application = New Microsoft.Office.Interop.Excel.Application()
    Dim xlWorkBook1, xlWorkBook2, xlWorkBook3 As Excel.Workbook
    Dim xlWorkSheet1, xlWorkSheet2, xlWorkSheet3 As Excel.Worksheet
    Dim misValue As Object = System.Reflection.Missing.Value
    Dim xlRange1 As Excel.Range
    Dim maxRows As Short
    Dim qtyChange, mtlChange, newItem, delItem As Boolean
    Dim newRowCount As Short = 1
    Dim w3row As Short = 1

    'Check if Excel is installed on system
    If xlApp1 Is Nothing Then
        MessageBox.Show("Excel is missing/not properly installed on your system.", "ERROR")
        Return
    End If

    xlApp1.Workbooks.Open(path1)
    xlWorkBook1 = xlApp1.ActiveWorkbook
    xlWorkSheet1 = xlWorkBook1.ActiveSheet

    xlApp2.Workbooks.Open(path2)
    xlWorkBook2 = xlApp2.ActiveWorkbook
    xlWorkSheet2 = xlWorkBook2.ActiveSheet

    'Get maximum number of columns and rows from new spreadsheet
    maxRows = xlWorkSheet2.UsedRange.Rows.Count

    pbStatus.Minimum = 1
    pbStatus.Maximum = maxRows

                Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue)

    '----------------------------------
    'End of process, cleaning up CPU---
    xlWorkBook1.Close(True, misValue, misValue)
    xlApp1.Quit()

    xlWorkBook2.Close(True, misValue, misValue)
    xlApp2.Quit()

    ReleaseObject(xlWorkSheet1)
    ReleaseObject(xlWorkBook1)
    ReleaseObject(xlApp1)

    ReleaseObject(xlWorkSheet2)
    ReleaseObject(xlWorkBook2)
    ReleaseObject(xlApp2)

    ReleaseObject(xlWorkSheet3)
    ReleaseObject(xlWorkBook3)
    ReleaseObject(xlApp3)

    cmdFormat.Text = "Process complete. Compare new files?"
End Sub

編輯：什么不起作用？ 它將跳過相同的行，並檢測單元格的變化（我設置了第4列和第6列，將其返回為綠色/黃色），但是一旦我的代碼在舊工作表中找到了已刪除的條目/在新工作表中找到了新條目，就會弄亂。

我認為這是混亂的地方：

ElseIf GetCellData(xlWorkSheet1, newRowCount, 3) <> GetCellData(xlWorkSheet2, i, 3) And _
        GetCellData(xlWorkSheet1, newRowCount, 4) <> GetCellData(xlWorkSheet2, i, 4) Then

        If GetCellData(xlWorkSheet1, newRowCount + 1, 4) <> GetCellData(xlWorkSheet2, i, 4) Then
            newItem = True
        ElseIf GetCellData(xlWorkSheet1, newRowCount, 4) <> GetCellData(xlWorkSheet2, i + 1, 4) Then
            delItem = True
        End If
    End If

如果有人可以看到此問題，請通知我。 或者，如果您對此有其他解決方案。 謝謝！

Answer 1

抱歉，我沒有得到更多幫助。 絕對有點棘手。 我本人會把每張紙放入數據表中並在那里進行比較。 這就是我用來確定程序在兩組數據之間的新的/已完成的質量檢查的方式：

http://i.imgur.com/iuI1dGL.png

我做的事情和你的情況有所不同。

我使用這種方法將所需的數據從excel文件拉到數據表中。

這比使用excel interop一次讀取每一行要快得多。

獲取Excel數據並使用它來填充數據表：

//////////////////////////////////////////////////////////////////////////////////
//This function is absolute magic >.> - Fill DataTable with excel spreadsheet
//HDR=YES means "Spreadsheet has headers" Change to NO if not.
//name = "Log"; - This is the Sheet name to pull the data from
//////////////////////////////////////////////////////////////////////////////////
//oconn takes an SQL like command (Select Everything from name sheet) using con
//HDR=YES means that our data has headers :)
//////////////////////////////////////////////////////////////////////////////////
String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + copyToPath + ";Extended Properties='Excel 12.0 XML;HDR=YES;';";
OleDbConnection con = new OleDbConnection(constr);
OleDbCommand oconn = new OleDbCommand("Select * From [Log$]", con);
con.Open();
OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
DataTable data = new DataTable();
sda.Fill(data);
con.Close();
//////////////////////////////////////////////////////////////////////////////////

這給我們留下了一個DataTable，其中包含excel電子表格的所有行/標題。

然后，我們可以使用相同的方法提取第二個。

到那時，我們將能夠比較C＃中的數據，以我的經驗，這要快得多。

最后，您可以使用Excel Interop導出到excel，而只需打開一個實例。
