也谈关于WORD的版本问题

[runsoft]

我使用的是office的xp版本,在加入引用msword.olb之后,操作word.
在使用的过程中,不知道为什么代码和CSDN和csharp的帮助中代码出入很大,比如
object fileName = "c:\\database\\test.doc";
object readOnly = false;
object isVisible = true;
object missing = System.Reflection.Missing.Value;
Word.ApplicationClass oWordApp = new Word.ApplicationClass();

Word.Document oWordDoc = oWordApp.Documents.Open(ref fileName,
ref missing,ref readOnly,
ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing,
ref missing, ref missing, ref isVisible,
ref missing,ref missing,ref missing);
其中我编写的代码中oWordApp没有Documents的属性.到是有一个get_Documents的方法.但是修改之后运行时候出现如下错误:
其他信息: 接口 Word._Application 的 QueryInterface 失败。
请高手指点.

具体代码如下:
object fileName = "c:\\model.doc";
object readOnly = false;
object isVisible = true;
object missing = System.Reflection.Missing.Value;
Word.ApplicationClass oWordApp = new Word.ApplicationClass();

oWordApp.set_Visible (true);

Word.Document oWordDoc = oWordApp.get_Documents ().Open(ref fileName,
ref missing,ref readOnly,
ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing,
ref missing, ref missing, ref isVisible,
ref missing,ref missing,ref missing);

出现错误信息: 未处理的“System.InvalidCastException”类型的异常出现在 Outlookbar.exe 中。

其他信息: 接口 Word._Application 的 QueryInterface 失败。

结果生成一个SunShine【20041026124871873080】的doc文档，即SunShine【"+GetRandomString()+"】.doc，并在文档中写入“SunShine is HuiChow”
