我通过使用以下代码尝试了此操作，但它引发了异常."Exception has been thrown by the target of an invocation."

I tried it by using the following code,but it threw an exception."Exception has been thrown by the target of an invocation."

System.Type wordType = System.Type.GetTypeFromProgID("Word.Application");
        Object word = System.Activator.CreateInstance(wordType);
        wordType.InvokeMember("Visible", BindingFlags.SetProperty, null, word, new Object[] { true });
        Object documents = wordType.InvokeMember("Documents", BindingFlags.GetProperty, null, word, null);
        object nullobj = Missing.Value;
        string fileName=System.AppDomain.CurrentDomain.BaseDirectory + "assets\\sample_doc.docx";
        object[] args = new object[15] { fileName, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, nullobj};
        Object document = documents.GetType().InvokeMember("Open", BindingFlags.InvokeMethod, null, documents,args);`

推荐答案

using (FileStream stream = new FileStream(FileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
 Document Doc = new Document(stream);
