kullanırken serileştirilemiyor, WebHttpBinding ile WCF hizmetini kullanıyorum. Enum dizileri olarak serileştirmek için özel IDataContractSurrogate uygulamasını yazdım.WCF IDataContractSurrogate
Enumlar seri hale getirme İŞLER, ancak seri hale getirme başarısız oluyor. istek enum içerdiğinde
, o zaman ben alıyorum: (400) Geçersiz İstek:
Uzak sunucu beklenmeyen bir yanıt döndürdü. yanıtı Bir enum içerdiğinde
ya, o zaman ben alıyorum:
InvalidCastException: Specified cast is not valid

sunucu kodu:
string baseAddress = "http://localhost:8733/Design_Time_Addresses/FingerprintService/";
_serviceHost = new WebServiceHost(myServiceInstance, new Uri(baseAddress));
_serviceHost.AddServiceEndpoint(typeof (IMyService), new WebHttpBinding(WebHttpSecurityMode.None), baseAddress);
EndpointExtension.Setup(_serviceHost.Description.Endpoints[0]);
_serviceHost.Open();
istemci kodu:
IMyService FingerprintService()
{
var channelFaftory = new WebChannelFactory<IMyService>(new Uri(TbxUri.Text));
EndpointExtension.Setup(channelFaftory.Endpoint);
return channelFaftory.CreateChannel();
}
uç nokta kurulumu (ortak hem ana bilgisayar hem de istemci için):
public static void Setup(ServiceEndpoint endpoint)
{
var webHttpBehavior = endpoint.Behaviors.Find<WebHttpBehavior>();
if (webHttpBehavior == null)
{
webHttpBehavior = new WebHttpBehavior();
endpoint.Behaviors.Add(webHttpBehavior);
}
foreach (OperationDescription opertion in endpoint.Contract.Operations)
{
var dataContractBehavior = opertion.Behaviors.Find<DataContractSerializerOperationBehavior>();
dataContractBehavior.DataContractSurrogate = new EnumSurrogate();
}
}
}
ve sonda gelen, vekil:
public class EnumSurrogate : IDataContractSurrogate
{
public Type GetDataContractType(Type type)
{
if (type.IsEnum)
{
return typeof(string);
}
return type;
}
public object GetObjectToSerialize(object obj, Type targetType)
{
if (obj is Enum)
{
return obj.ToString();
}
return obj;
}
public object GetDeserializedObject(object obj, Type targetType)
{
if (obj is string && targetType.IsEnum)
{
return Enum.Parse(targetType, (string)obj);
}
return obj;
}
//other methods throws NotImplementedException
