我有一个 Web 服务,它将以下内容作为字节数组序列化并返回给客户端:
[Serializable]
public class MyFile
{
public byte[] Data;
public string FileName;
}
也就是说,我将List(Of MyFile)返回给客户端。
它由具有以下 TYPENAME 的客户端使用
System.Collections.Generic.List`1[[NorwayTaxService.Streaming+MyFile, NorwayTaxService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]
程序集名称为:
mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
我正在使用以下两个类来绑定反序列化:
[Serializable]
public class MyFileLocal : ISerializable
{
public byte[] Data;
public string FileName;
// The security attribute demands that code that calls
// this method have permission to perform serialization.
[SecurityPermissionAttribute(SecurityAction.Demand, SerializationFormatter = true)]
void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
{
info.AddValue("Data", Data);
info.AddValue("FileName", FileName);
}
// The security attribute demands that code that calls
// this method have permission to perform serialization.
[SecurityPermissionAttribute(SecurityAction.Demand, SerializationFormatter = true)]
private MyFileLocal(SerializationInfo info, StreamingContext context)
{
Data = (byte[])info.GetValue("Data", Data.GetType());
FileName = info.GetString("FileName");
}
}
sealed class MyFileWebToLocalVersionBinder : SerializationBinder
{
public override Type BindToType(string assemblyName, string typeName)
{
Type typeToDeserialize = null;
// For each assemblyName/typeName that you want to deserialize to
// a different type, set typeToDeserialize to the desired type.
String assemVer1 = Assembly.GetExecutingAssembly().FullName;
String typeVer1 = "NorwayTax.Streaming+MyFile";
if (assemblyName == assemVer1 && typeName == typeVer1)
{
// To use a type from a different assembly version,
// change the version number.
// To do this, uncomment the following line of code.
// assemblyName = assemblyName.Replace("1.0.0.0", "2.0.0.0");
// To use a different type from the same assembly,
// change the type name.
typeName = "MyFileLocal";
}
typeToDeserialize = Type.GetType(String.Format("{0}, {1}", typeName, assemblyName));
return typeToDeserialize;
}
}
但是对于我的一生,并尝试了 GETTYPE 语句的许多变体,我的 TYPE 始终为 NULL。
例如,根据 STACKOVERFLOW 上的帖子,我尝试过:
typeToDeserialize = Type.GetType(String.Format("{0}, {1}", "System.Collections.Generic.List`1[[NorwayTax.Streaming+MyFile, NorwayTax]]", assemblyName));
但它没有用:(
