Get the author and subject of a Word document

Of course, first add a reference to the component of Word, add a reference to the namespace, code:

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 ();

Get author

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");

Get a topic

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

{

Close Word Process

Object save = false;

Oword.quit (ref save,ref unknown,ref Unknown);

System.Runtime.InteropServices.Marshal.ReleaseComObject (oword);

}
