博客展示了通过C#代码获取Word文档作者和主题的方法。先添加对Word组件和命名空间的引用，接着打开指定路径的Word文档，利用反射机制获取文档的内置属性，进而提取作者和主题信息，最后关闭Word进程。

当然要先添加对Word的组件的引用，添加命名空间的引用，代码：

Word.Application oWord;

Word._Document oDoc;

object oMissing = Missing.Value;

object docBuiltInProps;

object Source = @"DocPath";

object Unknown =Type.Missing;

oWord = new Word.Application();

            try
            {
                oDoc = oWord.Documents.Open(ref Source,ref Unknown,
                    ref Unknown,ref Unknown,ref Unknown,
                    ref Unknown,ref Unknown,ref Unknown,
                    ref Unknown,ref Unknown,ref Unknown,
                    ref Unknown );

                docBuiltInProps = oDoc.BuiltInDocumentProperties;

                Type typeDocBuiltInProps = docBuiltInProps.GetType();


                //获取作者
                string index = "Author";
                string propsValue;

                object docAuthor = typeDocBuiltInProps.InvokeMember("Item",
                    BindingFlags.Default |
                    BindingFlags.GetProperty,
                    null,docBuiltInProps,
                    new object[] {index} );

                Type typeDocAuthorProp = docAuthor.GetType();

                propsValue = typeDocAuthorProp.InvokeMember("Value",
                    BindingFlags.Default |
                    BindingFlags.GetProperty,
                    null,docAuthor,
                    new object[] {} ).ToString();

                MessageBox.Show( propsValue,"Author" );

                //获取主题
                index = "Subject";
                propsValue = "The Subject";

                object docSubjectProp = typeDocBuiltInProps.InvokeMember("Item",
                    BindingFlags.Default |
                    BindingFlags.GetProperty,
                    null,docBuiltInProps,
                    new object[] {index} );

                Type typeDocSubjectProp = docSubjectProp.GetType();

                propsValue = typeDocSubjectProp.InvokeMember("Value",
                    BindingFlags.Default |BindingFlags.GetProperty,
                    null,docSubjectProp,
                    new object[] {} ).ToString();

                MessageBox.Show( propsValue,"Subject" );

            }

            finally
            {
                //关闭word进程
                object save = false;

                oWord.Quit(ref save,ref Unknown,ref Unknown);

                System.Runtime.InteropServices.Marshal.ReleaseComObject(oWord);
            }
