WCF 自己调用两次或更多次，但前提是我保留代码行（我需要它）

Question

我有一个奇怪的问题。我做了几个工作 wcf。我已经更新了其中一个，似乎一切正常。

但是，如果我在浏览器中调用带有 get 的方法，我会得到 ERR_CONNECTION_RESET。调试它，我发现代码在循环，调用自己两次或三次，而调用只有一次。

代码确实和其他的差不多，但是有一点看不懂

为什么会循环？

这是我的方法的代码：

    public List<WrapImpianti> GetImpianto(string codret, string storeID, string hashedString, string outputType)
    {
        Utility.Logger("GetImpianto: start " + outputType);
        var md5 = new md5Manager();
        string key = "";
        IS_RETISTI retista = getRetista(codret);
        if (retista != null)
            key = retista.CHIAVEDES;
        List<WrapImpianti> r = new List<WrapImpianti>();
        //return r;
        if (md5.checkHashedInput(codret + storeID, hashedString, key))
        {
            try
            {
                using (var db = new AccessData.Entities())
                {
                    var t = db.IS_IMPIANTI.Where(x => x.STOREID == storeID && x.IDRET == retista.ID).ToList();
                    r = t.Select(x => new WrapImpianti(x, key)).ToList();
                }
                return r;
            }
            catch (Exception ex)
            {
                throw new WebFaultException<string>(ex.Message, HttpStatusCode.Conflict);
            }
        }
        else
            throw new WebFaultException<string>("Hash non corretto", HttpStatusCode.BadRequest);
    }

如果我注释行 "r = t.Select(x => new WrapImpianti(x, key)).ToList();"，它会起作用...或者至少，它 return 是一个没有循环的空对象（因为我没有填充它）。

为什么？它只调用我的 class WrapImpianti...

的 init 方法

这是class

            set { p_PROPRIETARIO = value; }
        }
    }

为什么，如果我调用 class init 方法，它会开始循环吗？然后，为什么 return ERR_CONNECTION_RESET?

Answer 1

好的，这很有趣。解决方案在这里：

    public string PROPRIETARIO
    {
        get
        {
            if (model == null)
                return p_PROPRIETARIO.ToSafeString();
            else
            {
                using (var db = new AccessData.Entities())
                {
                    return db.IS_PROPRIETARI.FirstOrDefault(x => x.ID == this.model.IDPRP).CODICE.ToSafeString();
                }
            }
        }
        set { p_PROPRIETARIO = value; }

在我的自定义类中..有时，IDPRP 为空并引发此错误。

非常有趣：我原以为这种类型的错误对开发人员来说更明显，而不是循环本身并得到一个匿名错误。

希望它对某人有用。 ;)
