如何使用 Google 协议缓冲区创建通用反序列化器？ 使用 C#

Question

I am trying to use Google protocol buffer library for serializing and deserialzing process in C#. I can deserialize using following code NotificationSet.Parser.ParseJson(json); And this is working fine.

NotificationSet is auto generated file by.proto.

But here you can see it is not generic. So, instead of specif type i need to make a method in generic way. Can you please advice on this?

Example:

public async Task<TResult> Deserialize<TResult, TValue>(TValue value)
    {
        TResult.Parser.ParseJson(value.ToString());
    }

Problem is TResult is generic type, so unable to get Parser method from that.

Found an answer.

Try with is code to achieve generic deserialization process using google protocol buffer library.

 public async Task<TResult> Deserialize<TResult,TValue>(TValue value)
    {
        try
        {
            System.Type type = typeof(TResult);
            var typ = Assembly.GetExecutingAssembly().GetTypes().First(t => t.Name == type.Name);
            var descriptor = (MessageDescriptor)typ.GetProperty("Descriptor", BindingFlags.Public | BindingFlags.Static).GetValue(null, null); 
            var response = descriptor.Parser.ParseJson(value.ToString());
            return await Task.FromResult((TResult)response);


        }
        catch (Exception ex)
        {

            throw ex;
        }
    }
}
