C# XmlDictionaryReader读取固定大小的归零流

有人能给我一个很好的解释为什么这会失败吗

const int bufferSize = 2 * 1024, testValue = 123456;
var buffer = new byte[bufferSize];

var serializer = new DataContractSerializer(typeof(int));

//Serialize value
using (var memStream = new MemoryStream(buffer))
using (XmlDictionaryWriter writer = XmlDictionaryWriter.CreateBinaryWriter(memStream))
    serializer.WriteObject(writer, testValue);

//Deserialize value
using (var memStream = new MemoryStream(buffer))
using (XmlDictionaryReader reader = XmlDictionaryReader.CreateBinaryReader(memStream, XmlDictionaryReaderQuotas.Max))
{
    object deserializedValue = serializer.ReadObject(reader); // <--- nope, this throws System.Runtime.Serialization.SerializationException: The input source is not correctly formatted.
    Console.WriteLine(deserializedValue);
}

const int bufferSize=2*1024，testValue=123456；
var buffer=新字节[bufferSize]；
var serializer=新的DataContractSerializer（typeof（int））；
//序列化值
使用（var memStream=newmemoryStream（缓冲区））
使用（XmlDictionaryWriter=XmlDictionaryWriter.CreateBaryWriter（memStream））
serializer.WriteObject（writer，testValue）；
//反序列化值
使用（var memStream=newmemoryStream（缓冲区））
使用（XmlDictionaryReader=XmlDictionaryReader.CreateBinaryReader（memStream，XmlDictionaryReaderQuotas.Max））
{
object deserializedValue=serializer.ReadObject（reader）；//当然我会帮你解决这个问题（因为没有其他人会费心去确认/否认症状）

我发现读卡器读取无效数据确实存在问题。不过，您可以通过在流的末尾写入空格来帮助它，如下所示：

//Serialize value
using (var memStream = new MemoryStream(buffer))
using (XmlDictionaryWriter writer = XmlDictionaryWriter.CreateBinaryWriter(memStream))
{
    serializer.WriteObject(writer, testValue);
    writer.WriteWhitespace(" ");
}

//Deserialize value
using (var memStream = new MemoryStream(buffer))
using (XmlDictionaryReader reader = XmlDictionaryReader.CreateBinaryReader(memStream, XmlDictionaryReaderQuotas.Max))
{
    object deserializedValue = serializer.ReadObject(reader); // \o/
    Console.WriteLine(deserializedValue);
}

真不敢相信没有人会这么喜欢这个问题，因为它可能会导致运行时难以调试异常，从而使使用XmlDictionaryWriter序列化对象有点不可靠

连接报告：
您需要添加Flush（）命令：

//Serialize value
using (var memStream = new MemoryStream(buffer))
using (XmlDictionaryWriter writer = XmlDictionaryWriter.CreateBinaryWriter(memStream))
{
    serializer.WriteObject(writer, testValue);
    writer.WriteWhitespace(" ");
}

//Deserialize value
using (var memStream = new MemoryStream(buffer))
using (XmlDictionaryReader reader = XmlDictionaryReader.CreateBinaryReader(memStream, XmlDictionaryReaderQuotas.Max))
{
    object deserializedValue = serializer.ReadObject(reader); // \o/
    Console.WriteLine(deserializedValue);
}

//Serialize value
using (var memStream = new MemoryStream(buffer))
using (XmlDictionaryWriter writer = XmlDictionaryWriter.CreateBinaryWriter(memStream))
{
    serializer.WriteObject(writer, testValue);
    writer.Flush();
}
