I'm new to the thrift. I need to convert my data object to a JSON string with Thrift JSON serialization.
I tried in this way.
TSerializer serializer = new TSerializer(new TSimpleJSONProtocol.Factory()); String json = serializer.toString(object_name); In here is an error, that object_name should be in TBase. How can I resolve this ?

Next time, please post the exact error message (use copy+paste), this makes it easier for all of us.

Whatever you want to serialize with Thrift, must be an descendant of Thrift's TBase class. You achieve this by writing some Thrift IDL and save it as a file (e.g. MyDataStructs.thrift):
struct Employee { 1: string name 2: string surname 3: i32 age } Next, you pass that file to the Thrift compiler and tell him to generate some C# code from it:
thrift -gen csharp MyDataStructs.thrift This gives you a class derived from TBase:
public partial class Employee : TBase { private string _name; private string _surname; private int _age; // properties public string Name {... } public string Surname { ... } public int Age { ... } // some details omitted public void Read (TProtocol iprot) { // generated code for Read() method } public void Write(TProtocol oprot) { // generated code for Write() method } public override string ToString() { // generated code for ToString() method } } This is what Thrift expects.
If below is what your are doing then it should work. Check if you are doing this. Employee is a demo call here, you have to use your actual class.
Employee object_name= new Employee(); object_name.setAge(27); object_name.setName("Test"); TSerializer serializer = new TSerializer(new TSimpleJSONProtocol.Factory()); String json = serializer.toString(object_name);
