Question

我正在尝试使用此代码提取单词内容：

// Open a doc file.
            Application application = new Application();
            Document document = application.Documents.Open("d:\\a.doc");

            // Loop through all words in the document.
            int count = document.Words.Count;
            for (int i = 1; i <= count; i++)
            {
                // Write the word.
                string text = document.Words[i].Text;
                Console.WriteLine("Word {0} = {1}", i, text);
            }
            // Close word.
            application.Quit();

但是在跑完之后我得到了这个错误：

    Unable to cast COM object of type 'Microsoft.Office.Interop.Word.ApplicationClass' to interface type 
'Microsoft.Office.Interop.Word._Application'. This operation failed
 because the QueryInterface call on the COM component for the 
interface with IID '{00020970-0000-0000-C000-000000000046}'
 failed due to the following error:
 No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

我已安装Office 2013

我终于下载aspire.doc nuget并使用它来提取word文件的内容，如你所见：

   Document document = new Document();
            document.LoadFromFile(@"d:\a.docx");

            //Initialzie StringBuilder Instance
            StringBuilder sb = new StringBuilder();

            //Extract Text from Word and Save to StringBuilder Instance
            foreach (Section section in document.Sections)
            {
                foreach (Paragraph paragraph in section.Paragraphs)
                {
                    sb.AppendLine(paragraph.Text);
                }
            }

            //Create a New TXT File to Save Extracted Text
            Console.WriteLine(sb.ToString());
            Console.ReadLine();

使用word interop提取单词内容会导致错误
