VB.net读取Word文档属性的方法

复制代码 代码如下:
'对自定义属性进行读取
         Dim Properties = SourceDoc.CustomDocumentProperties
            Dim PropertyType As Type = Properties.GetType

        Try
            Dim Authorprop = PropertyType.InvokeMember("Item", Reflection.BindingFlags.Default Or Reflection.BindingFlags.GetProperty, Nothing, Properties, New Object() {"备注"})
            ResultString = Authorprop.GetType.InvokeMember("Value", Reflection.BindingFlags.Default Or Reflection.BindingFlags.GetProperty, Nothing, Authorprop, New Object() {})

        Catch ex As Exception

        End Try
 　　　'写入　
　　　　Dim Authorprop = PropertyType.InvokeMember("Item", Reflection.BindingFlags.Default Or Reflection.BindingFlags.SetProperty, Nothing, properties, New Object() {"备注", ResultString})

另一种写法：
复制代码 代码如下:
'增加新属性
SourceDoc.CustomDocumentProperties.Add(Name := "PropertyName", LinkToContent := False, Type := Microsoft.Office.Core.MsoDocProperties.msoPropertyTypeString, Value := "PropertyValue")

'修改属性
SourceDoc.CustomDocumentProperties("PropertyName").Value = PropertyValue

'获取属性值
PropertyValue =SourceDoc.CustomDocumentProperties("PropertyName").Value

复制代码 代码如下:
'读取内置属性，以备注为例
 ResultString= SourceDoc.BuiltInDocumentProperties(Microsoft.Office.Interop.Word.WdBuiltInProperty.wdPropertyComments).value

读取写入操作后可以通过在Word文档上右键->属性查看效果，但当Word文档处于打开状态时，文档上右键是没有“自定义”和“摘要”这两个Tab的。
