尝试在Silverlight中反序列化时出现异常. Test1失败,而Test2成功.我也尝试将TypeNameAssemblyFormat同时用于Simple和Full,但得到相同的结果. Test2可以解决程序集,为什么不能Json.NET？
更新：忘记提及我尝试反序列化的类型是在与反序列化发生的silverlight程序集不同的程序集中定义的.
这两个测试都在非Silverlight .NET应用程序中运行.
如何反序列化具有类型名称的json字符串？
private void Test1()
{
JsonSerializerSettings settings = new JsonSerializerSettings();
settings.TypeNameHandling = TypeNameHandling.Objects;
string json1 = "{\"$type\":\"AmberGIS.NetworkTrace.DTO.NTPoint,NetworkTrace.DTO.Assembly\",\"X\":0.0,\"Y\":0.0,\"SpatialReference\":null}";
try
{
var n1 = JsonConvert.DeserializeObject<NTPoint>(json1,settings);
//Error resolving type specified in JSON 'AmberGIS.NetworkTrace.DTO.NTPoint,NetworkTrace.DTO.Assembly'.
//Could not load file or assembly 'NetworkTrace.DTO.Assembly,Culture=neutral,PublicKeyToken=null' or one of its dependencies.
//The requested assembly version conflicts with what is already bound in the app domain or specified in the manifest.
//(Exception from HRESULT: 0x80131053)
}
catch (Exception ex)
{
while (ex != null)
{
Debug.WriteLine(ex.Message);
ex = ex.InnerException;
}
}
}
这个Test2成功了：
private void Test2()
{
var pnt1 = new AmberGIS.NetworkTrace.DTO.NTPoint();
Debug.WriteLine(pnt1.GetType().AssemblyQualifiedName);
// "AmberGIS.NetworkTrace.DTO.NTPoint,NetworkTrace.DTO.Assembly,Version=1.0.0.0,PublicKeyToken=null"
string fullName = "AmberGIS.NetworkTrace.DTO.NTPoint,PublicKeyToken=null";
var t = Type.GetType(fullName);
var pnt2 = Activator.CreateInstance(t) as NTPoint;
}
尝试将设置添加到JsonConvert.DeserializeObject< T>(json,设置),
其中设置为：
其中设置为：
new JsonSerializerSettings
{
TypeNameHandling = TypeNameHandling.Objects,TypeNameAssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Full
}
