SOAP経由で送信されたオブジェクトのシリアル化

Question

私は、保存しようとしているMicrosoft CRMに対するSOAP要求/応答を扱っています。シリアライズしようとしているResponseオブジェクトはMicrosoft.Xrm.Sdk.Metadata.OptionSetMetadataBase（https://msdn.microsoft.com/en-us/library/microsoft.xrm.sdk.metadata.optionsetmetadata.aspx）です。私は、この拡張メソッドを使用して、私のオブジェクトをシリアル化しようとすると：

public static string Serialize(this IExtensibleDataObject obj, bool indent = false) 
{ 
    NetDataContractSerializer contractSerializer = new NetDataContractSerializer(); 
    using (StringWriter stringWriter = new StringWriter((IFormatProvider) CultureInfo.InvariantCulture)) 
    { 
    using (XmlTextWriter xmlTextWriter = new XmlTextWriter((TextWriter) stringWriter)) 
    { 
     if (indent) 
     { 
     xmlTextWriter.Formatting = Formatting.Indented; 
     xmlTextWriter.Indentation = 2; 
     } 
     contractSerializer.WriteObject((XmlWriter) xmlTextWriter, (object) obj); 
     return stringWriter.ToString(); 
    } 
    } 
} 

私はこのエラーを取得する：私はちょうどSOAPリクエストを経由してこの情報を取得したので、私はこれが可能であると仮定します

ので、それはちょうど逆シリアル化されました。これが役に立った場合、以下のSOAP応答があります。

このエラーを回避するにはどうすればよいですか？

Answer 1

代わりにDataContractSerializerを使用してください。それはジョブを実行します。それがあったことを

public static string Serialize(this IExtensibleDataObject obj, bool indent = false) 
    { 
     DataContractSerializer contractSerializer = new DataContractSerializer(obj.GetType()); 
     using (StringWriter stringWriter = new StringWriter(CultureInfo.InvariantCulture)) 
     { 
      using (XmlTextWriter xmlTextWriter = new XmlTextWriter(stringWriter)) 
      { 
       if (indent) 
       { 
        xmlTextWriter.Formatting = Formatting.Indented; 
        xmlTextWriter.Indentation = 2; 
       } 
       contractSerializer.WriteObject(xmlTextWriter, obj); 
       return stringWriter.ToString(); 
      } 
     } 
    }
