是否可以从Microsoft.Office.Interop.Word.dll组装load

Question

当我尝试这个时

    oAssembly = Assembly.LoadFrom("C:\dynamicdlls\Microsoft.Office.Interop.Word.dll")
    oType = oAssembly.GetType("Microsoft.Office.Interop.Word.Application")

    Try
        oObject = Activator.CreateInstance(oType)
        Dim doc As Object = oObject.Documents.Open("C:\worddoc\test.docx")

        Dim count As Integer = doc.Words.Count
        For i As Integer = 1 To count
            Dim text As String = doc.Words(i).Text
            Console.WriteLine("Word {0} = {1}", i, text)
        Next

        oObject.Quit()
    Catch ex As Exception
        MsgBox(ex.ToString)
    End Try

我得到“无法创建接口的实例”。

我知道有一个更好的替代方案，我只是在探索这种方法，并想知道这是否可行以及如何做到这一点。
