获取Word文档的作者和主题

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.ApplicationoWord;
Word._DocumentoDoc;
objectoMissing=Missing.Value;
objectdocBuiltInProps;

objectSource=@"DocPath";
objectUnknown=Type.Missing;
oWord=newWord.Application();

try
{
oDoc=oWord.Documents.Open(refSource,refUnknown,
refUnknown,refUnknown,refUnknown,
refUnknown,refUnknown,refUnknown,
refUnknown,refUnknown,refUnknown,
refUnknown);

docBuiltInProps=oDoc.BuiltInDocumentProperties;

TypetypeDocBuiltInProps=docBuiltInProps.GetType();


//获取作者
stringindex="Author";
stringpropsValue;

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

TypetypeDocAuthorProp=docAuthor.GetType();

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

MessageBox.Show(propsValue,"Author");

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

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

TypetypeDocSubjectProp=docSubjectProp.GetType();

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

MessageBox.Show(propsValue,"Subject");

}
finally
{
//关闭word进程
objectsave=false;

oWord.Quit(refsave,refUnknown,refUnknown);

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