我正在尝试打开放在Windows窗体上的WorkBookView
(在下面给出的代码中命名为wkbMain
)中的现有文件。我使用以下代码:
Private Sub MenuItemOpen_Click(sender As Object, e As EventArgs)
Dim lObjDialog As New OpenFileDialog
wkbMain.GetLock()
Try
If lObjDialog.ShowDialog() = DialogResult.OK Then
wkbMain = SpreadsheetGear.Factory.GetWorkbook(lObjDialog.FileName, System.Globalization.CultureInfo.CurrentCulture)
End If
Catch ex As Exception
Finally
wkbMain.ReleaseLock()
End Try
End Sub
但是作业
wkbMain = SpreadsheetGear.Factory.GetWorkbook(lObjDialog.FileName, System.Globalization.CultureInfo.CurrentCulture)`)
抛出异常:
无法投射类型'ᢷ'输入' SpreadsheetGear.Windows.Forms.WorkbookView'。
请建议解决方案
答案 0 :(得分:1)
您需要将WorkbookView。ActiveWorkbook属性设置为Factory.GetWorkbook(...)返回的对象,而不是WorkbookView对象本身。例如:
wkbMain.ActiveWorkbook = SpreadsheetGear.Factory.GetWorkbook(lObjDialog.FileName,
System.Globalization.CultureInfo.CurrentCulture))
