C#獲取Word文檔的作者和主題代碼

當然要先添加對Word的組件的引用，添加命名空間的引用，代碼：

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();


//獲取作者
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" );

//獲取主題
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
{
//關閉word進程
object save = false;

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

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