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，如果我在浏览器中使用get调用方法，则会得到ERR_CONNECTION_RESET。对它进行补偿，我发现代码正在循环，当呼叫只有一个时，自己调用两次或三次。
代码与其他代码非常相似，但有些东西我无法理解。
为什么会循环？
这是我方法的代码：
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);
}
如果我评论该行＆＃34; r = t.Select（x =＆gt; new WrapImpianti（x，key））。ToList（）;＆＃34;，它可以...或者，至少，它返回一个空对象（因为我没有填充它）而没有循环。
为什么呢？它只调用我的类WrapImpianti的init方法......

为什么，如果我调用我的类init方法，它是否开始循环？然后，为什么它会返回ERR_CONNECTION_RESET？
答案 0 :(得分：0)
好的，这很有意思。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null并引发此错误。
它非常有用：我期望开发人员更容易看到这种类型的错误，而不是循环本身并得到匿名错误。
希望它对某人有用。 ;）
