我正在处理一些对Microsoft CRM的SOAP请求/响应，我正在尝试保存。我正在尝试序列化的Response对象是Microsoft.Xrm.Sdk.Metadata.OptionSetMetadataBase（https://msdn.microsoft.com/en-us/library/microsoft.xrm.sdk.metadata.optionsetmetadata.aspx）。当我尝试使用此扩展方法序列化我的对象时：
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();
}
}
}
我收到此错误：
threw an exception of type 'System.Runtime.Serialization.InvalidDataContractException'
Data: {System.Collections.ListDictionaryInternal}
HResult: -2146233088

我认为这是可能的，因为我只是通过SOAP请求检索此信息，因此它只是反序列化。如果它有帮助，这是肥皂反应：

如何解决此错误？
答案 0 :(得分：3)
使用DataContractSerializer代替 - 它将完成这项工作。它可以序列化未标记[DataContract]或[Serializable]属性的类型（默认构造函数是必需的+仅公共成员将被序列化）：
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();
}
}
}
