vb.net - 如何使用 Excel.Workbook 操作 Excel 工作簿

Question

所以，我找不到在Excel.WorkbookorExcel.Application中打开文件的任何方法，我想知道为什么。

我有一个 Excel 文件的路径，我想操作它。我知道我必须使用Excel.Application,Excel.Workbook和Excel.Worksheet。Excel文件的文件是ExcelFilePath，我应该怎么做才能使它成为可能？

Answer 1

您首先需要添加对Microsoft.Office.Interop.Excel项目的引用才能使用 Excel API，然后填写变量：

Dim xlApp As Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim xlWS As Excel.Worksheet

xlApp = New Excel.ApplicationClass
xlWorkBook = xlApp.Workbooks.Open(sFilePath)
xlWS = CType(xlWorkBook.Worksheets(sheetNameOrIndex), Excel.Worksheet)

然后你只需要使用他们拥有的方法。例如：

Dim sVar as String = xlWS.Range("C5").Value.ToString()

Answer 2

试试这个：从我的项目

Dim xapp As New Microsoft.Office.Interop.Excel.Application
    Dim wb As Workbook = xapp.Workbooks.Add
    Dim ws As Worksheet = wb.Worksheets(1)
    ws.Activate()

    'Fill header of the sheet----------------------------------
    For i As Integer = 1 To dgvcustomer.Columns.Count
        ws.Cells(1, i) = dgvcustomer.Columns(i - 1).HeaderText
    Next
    'End header------------------------------------------------

    Dim Dgrow, Dgcell, Dgcol As Integer
    Dgrow = 1
    Dgcell = 1

    'Fill Sheet ------------------------------------------------------------------------------------------------

    While (Dgrow <= dgvcustomer.Rows.Count)
        Dgcol = 1
        While (Dgcol <= ws.UsedRange.Columns().Count)
            ws.Cells(Dgrow + 1, Dgcol).value = dgvcustomer.Rows(Dgrow - 1).Cells(ws.Cells(1, Dgcol).value).Value
            Dgcol += 1
        End While
        Dgrow += 1
    End While

    'End fill sheet---------------------------------------------------------------------------------------------

    wb.SaveAs(dlgSaveFile.FileName)
    wb.Close()
    xapp.Quit()
