WCF REST - 如何将流读取为文本
我有一个 WCF REST 服务。每个传入消息的 XML 正文都被反序列化为我的对象，如下所示：
private static Message MyMethod(Stream stream)
{
try
{
var serializer = new XmlSerializer(typeof(MyObject));
var myObject = (MyObject)serializer.Deserialize(stream);
//do stuff
}
catch (InvalidOperationException invEx)
{
//write stream (xml) to error log
}
//etc
}
我希望能够在反序列化失败时写入要记录的 XML。我尝试过的所有结果都是空字符串。这可能吗？
谢谢！
I have a WCF REST Service. The XML body of each incoming message is deserialized into my objects as follows:
private static Message MyMethod(Stream stream)
{
try
{
var serializer = new XmlSerializer(typeof(MyObject));
var myObject = (MyObject)serializer.Deserialize(stream);
//do stuff
}
catch (InvalidOperationException invEx)
{
//write stream (xml) to error log
}
//etc
}
I would like to be able to write the XML to log when the Deserialization fails. Everything I have tried results in an Empty String. Is this even possible?
Thanks!

您可以轻松地将整个内容作为
string而不是Stream引入，并从中加载/反序列化。Stream有什么特殊原因吗？或者（更好，IMO），您可以将要反序列化的对象指定为
DataContract并在您的操作合约中要求 XML，并让 WCF 框架完成工作你。You could easily bring the whole thing in as a
stringrather than aStream, and load/deserialize from that. Is there a particular reason for theStream?Alternatively (better, IMO), you can specify the object you want de-serialized as a
DataContractand require XML in your operation contract and let the WCF framework do the work for you.您是否尝试在写入错误日志之前重新定位流？
流.Position = 0;
Have you tried to reposition the stream before writing to the error log?
stream.Position = 0;
