我需要添加值在Word文档我的书签。在那里，我确实需要使用后期绑定来实现这一点。

我已经高达提取书签，但我要如何更改值？

 对象书签= @OfferRef;
    键入applicationType = Type.GetTypeFromProgID（Word.Application）;
    反对的applicationObject = Activator.CreateInstance（applicationType）;

    反对documentsObject = applicationType.InvokeMember（文档，System.Reflection.BindingFlags.GetProperty，
     空，的applicationObject，NULL）;
    applicationType.InvokeMember（可见，System.Reflection.BindingFlags.SetProperty，空，的applicationObject，
     新对象[] {真}）;

    键入documentsType = documentsObject.GetType（）;
    反对documentObject = documentsType.InvokeMember（添加，BindingFlags.InvokeMethod，空，documentsObject，
     新对象[] {@E：\ offer.doc}）;

    键入documentType = documentObject.GetType（）;
    对象fieldsBookMarks = documentType.InvokeMember（书签，BindingFlags.GetProperty，空，documentObject，NULL）;
    键入typeBookMarks = fieldsBookMarks.GetType（）;

    对象书签= typeBookMarks.InvokeMember（项目，BindingFlags.InvokeMethod，空，fieldsBookMarks，新的对象[] {书签}）;
    类型类型= bookMark.GetType（）;
    对象范围= type.InvokeMember（范围，BindingFlags.GetProperty，空，书签，NULL）;
    TYPE = Range.GetType（）;
 

解决方案

这是您在找什么？

另外，你可能想看看动态的关键字，在C＃4可用它会使你的code更容易编写和阅读。

比较code，如图4至code在图5

I need to add values for my "BookMarks" in a Word document. There I do need to achieve this using late binding.

I have extracted upto book mark, but how do I change the value?

    object bookMark = @"OfferRef";
    Type applicationType = Type.GetTypeFromProgID("Word.Application");
    object applicationObject = Activator.CreateInstance(applicationType);

    object documentsObject = applicationType.InvokeMember("Documents", System.Reflection.BindingFlags.GetProperty,
     null, applicationObject, null);
    applicationType.InvokeMember("Visible", System.Reflection.BindingFlags.SetProperty, null, applicationObject,
     new object[] { true });

    Type documentsType = documentsObject.GetType();
    object documentObject = documentsType.InvokeMember("Add", BindingFlags.InvokeMethod, null, documentsObject,
     new Object[] { @"e:\offer.doc"});

    Type documentType = documentObject.GetType();
    object fieldsBookMarks = documentType.InvokeMember("BookMarks", BindingFlags.GetProperty, null, documentObject, null);
    Type typeBookMarks = fieldsBookMarks.GetType();

    object bookMark = typeBookMarks.InvokeMember("Item", BindingFlags.InvokeMethod, null, fieldsBookMarks, new object[] { bookMark });
    Type type = bookMark.GetType();
    object Range = type.InvokeMember("Range", BindingFlags.GetProperty, null, bookMark, null);
    type = Range.GetType();

Is this what you are looking for?

In addition you might want to take a look at the dynamic keyword that is available in C# 4. It will make your code easier to write and read.

Compare the code in figure 4 to the code in figure 5
