VB.net读取Word文档属性

读取写入前需创建Word的引用,打开文件并获取Word的Document对象。

需要说明的一点是,Word自定义属性所能写入的长度是有限制的,约255个字符。

       '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:

’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 

 

 '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。
