        {<br />
            return View();<br />

                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);<br />
            }<br />
            author author = db.authors.Find(id);<br />
            if (author == null)<br />
            {<br />
                return HttpNotFound();<br />
            }<br />
            return View(author);<br />
        }<br />
<br />
        // POST: authors/Delete/5<br />

        [ValidateAntiForgeryToken]<br />
        public ActionResult DeleteConfirmed(string id)<br />
        {<br />
            author author = db.authors.Find(id);<br />
            db.authors.Remove(author);<br />
            db.SaveChanges();<br />
            return RedirectToAction("Index");<br />
        }<br />

推荐答案

我认为你正在使用EntityFramework，所以请确保连接字符串在web.config文件中可用。当您添加实体框架时，它会要求您将敏感数据添加到项目中。我想你会选择不。试试这个并告诉我。

I think you are using EntityFramework, so please make sure that the connection string is available in the web.config file. When you are adding the entity framework it will asks for you to add the sensitive data into the project or not. I think you would have select no. Try this and let me know.
