您好， 我一直在尝试编写一个使用OpenXML docmentformat生成Word文档的小程序。 在我的mainform中，我有一个创建文档的方法：

Hello, I have been trying to write a small program that generates a Word document using OpenXML docmentformat. In my mainform I have a method creating the document:

' Creates a WordprocessingDocument. Public Sub CreatePackage(filePath As String, text As String) Using package As WordprocessingDocument = WordprocessingDocument.Create(_filename, WordprocessingDocumentType.Document) ' Add a new main document part. package.AddMainDocumentPart() ' Create the Document DOM. package.MainDocumentPart.Document = New Document(New Body(New Paragraph(New Run(New Text(text))))) ' Save changes to the main document part. package.MainDocumentPart.Document.Save() End Using End Sub

当我运行程序时，我得到一个UnauthorizedAccessException访问路径'C：\ Temp'被拒绝。 我试过搜索网但是有51.000次点击这基本上不可能全部审查。我的安排和迄今为止我检查的内容： * Windows 7 Pro * Visual Studio 2010（以管理员身份运行） *我有PC上的管理员权限 *尝试使用

When I run the program I get a "UnauthorizedAccessException" Access to the path 'C:\Temp' is denied. I have tried searching the net but with 51.000 hits on this basically impossible to review them all. My settup and what I have checked so far: * Windows 7 Pro * Visual Studio 2010 (running as admin) * I have admin rights on PC * tried to add a app.manifest with

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

任何帮助都会赞赏。

Any help would appreciated.

推荐答案

我猜C：\ Temp是一个现有的文件夹，并希望您正确设置访问权限 - 因此C：\ Temp不是文件的可接受名称。 我看到你的函数使用 CreatePackage（filePath As String ，而你调用 WordprocessingDocument.Create（_filename 。您是否混淆了文件名？在您具有写入权限的文件夹中尝试不存在的文件名。 I guess C:\Temp is an existing folder, and hopefully you set the access rights correctly - hence C:\Temp is not an acceptable name for a file. I see that your function uses CreatePackage(filePath As String while the you call WordprocessingDocument.Create(_filename. Did you mix up the filenames? Try a non-existing filename in a folder where you have write access.
