Question

我正在研究ASP.NET MVC4，Web API，我尝试编写密码加密代码在Register controller中我写了这段代码

 namespace PasswordHash.Controllers
{
    public class RegisterController : ApiController
    {
        // GET api/values
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }

        // GET api/values/5
        public string Get(int id)
        {
            return "value";
        }

        //POST api/values
        public HttpResponseMessage Post(user user)
        {
            HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, "value");
            var db = new passwordhashEntities();
            var checkExitUser = (from c in db.users where c.UserName == user.UserName select c).Count();
            if (checkExitUser == 0)
            {
                var newUser = new user()
                {
                    Email = user.Email,
                    UserName = user.UserName,
                    Password = PasswordHashHelper.CreateHash(user.Password),
                    PostCode = user.PostCode,
                    SlowHash = user.SlowHash


                };
                db.users.Add(newUser);
                db.SaveChanges();
                response.Content = new StringContent("Resgister successfully ", Encoding.Unicode);
            }
            else
                response.Content = new StringContent(user.UserName + "is exit", Encoding.Unicode);

            return response;
        }

        // PUT api/values/5
        public void Put(int id, [FromBody]string value)
        {
        }

        // DELETE api/values/5
        public void Delete(int id)
        {
        }
    }
}

此行中的运行时错误apear：var checkExitUser =（来自db.users中的c，其中c.UserName == user.UserName select c）.Count（）; 错误是：类型＆＃39; System.Data.EntityException＆＃39;发生在System.Data.Entity.dll中但未在用户代码中处理

我想我需要安装一些工具或程序，但我不知道这个工具是什么？因为我试图应用其他加密教程，并且它也没有与我一起使用同样的错误。
