首先要添加一個引用：com ----> microsoft word 9.0 object library
要用到這個名稱空間：system.reflection

void opword()
{

word.application oword;
word._document odoc;
object docbuiltinprops;
object omissing = missing.value;
object source = server.mappath("liu.doc");
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 );

//下面代碼可以獲得word文本
response.write(odoc.words.count.tostring());
response.write("

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();

response.write(propsvalue);

//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();

response.write(propsvalue);
}
finally
{
//關閉word進程
object save = false;

oword.quit(ref save,ref unknown,ref unknown);

system.runtime.interopservices.marshal.releasecomobject(oword);
}
}
