VB.NET - 编辑文件属性“公司” ETC？

Question

我想知道如何设置文件的属性？我说的是字段、作者、公司等。我找到了一种通过 Word 的内置属性来实现的方法。但这有点麻烦。所以我想知道是否可以通过其他方式做到这一点？

我有这段代码适用于除 *.doc 格式之外的所有 Word 文档文件。 这是我到目前为止的代码，一个文本框和一个按钮。该按钮运行 findDocLoop()

    Dim oWord As Word.Application
    Dim oDoc As Word.Document
    Dim oBuiltInProps As Object

  Public Sub findDocLoop()
        Dim strRootPath As String
        strRootPath = txtBoxRootpath.Text

        Dim di As New IO.DirectoryInfo(strRootPath)
        Dim aryFi As IO.FileInfo() = di.GetFiles("*.doc")
        Dim aryFi2 As IO.FileInfo() = di.GetFiles("*.dot")
        Dim aryFi3 As IO.FileInfo() = di.GetFiles("*.doc*")

        Dim fi As IO.FileInfo


        For Each fi In aryFi
            If Not fi.FullName.Contains("~$") Then
                RunRenameProcess(txtBoxRootpath.Text & "\" & fi.ToString)
            End If
        Next

        For Each fi In aryFi2
            If Not fi.FullName.Contains("~$") Then
                RunRenameProcess(txtBoxRootpath.Text & "\" & fi.ToString)
            End If
        Next

        For Each fi In aryFi3
            If Not fi.FullName.Contains("~$") Then
                RunRenameProcess(txtBoxRootpath.Text & "\" & fi.ToString)
            End If
        Next

        oDoc = Nothing

        lblDone.Text = "Finished"

    End Sub

    Public Function FileInUse(ByVal sFile As String) As Boolean
        Dim thisFileInUse As Boolean = False
        If System.IO.File.Exists(sFile) Then
            Try
                Using f As New IO.FileStream(sFile, FileMode.Open, FileAccess.ReadWrite, FileShare.None)
                    thisFileInUse = False
                End Using
            Catch
                thisFileInUse = True
                writeToLog(sFile)
            End Try
        End If
        Return thisFileInUse
    End Function

    Public Sub writeToLog(ByVal strFile As String)
        Dim sContents As String
        sContents = strFile & " - " & DateTime.Now.ToLongTimeString
        SaveTextToFile(sContents, Directory.GetCurrentDirectory & "\errorlog.txt")
    End Sub

    Private Sub RunRenameProcess(ByVal strFile)

        If FileInUse(strFile) = False Then
            'Create instance of Word and make it visible
            'On Error Resume Next
            oDoc = oWord.Documents.Open(strFile)

            'Get the properties collection in file
            oBuiltInProps = oDoc.BuiltInDocumentProperties

            'Set the value of the properties
            oBuiltInProps.Item("Company").Value = txtBoxCompany.Text
            ' AT THIS POINT, THE PROPERTY IS ACTUALLY SET (IF I CHECK IN WORD)

            oDoc.Save()
            ' AT THIS POINT, THE PROPERTY IS RESET TO THE DEFAULT WORD COMPANY VALUE(DOMAIN)
            oDoc.Close()
        End If

    End Sub

我知道它可能可以做得更好，但我有点着急。我刚刚注意到当我在代码设置属性值之后设置断点时。我将 Word 设置为打开状态，进入其中并检查属性值。事实上它已经被设定了！但是保存之后，好像就丢失了。或“重置”为某些 Office 默认设置。这是我的公司名称。
