FieldBuilder

FieldBuilderRequest is a request to create FieldBuilder.

// Create service
IService service = Services.Create((ServiceHandlers.Instance, EmitHandlers.Instance), CachePolicies.Default);
// Request to create type builder
IRequestFor<TypeBuilder> typeBuilder = new TypeBuilderRequest("MyClass10F", TypeAttributes.Public | TypeAttributes.Class | TypeAttributes.AutoClass);
// Request to create field
IRequestFor<FieldBuilder> field = new FieldBuilderRequest(
    Name: "MyField",
    FieldType: typeof(int),
    Attributes: FieldAttributes.Public
);

Request is added as part of TypeBuilderRequest.

// Add field to type request
typeBuilder = typeBuilder.Append(field);

Try it in an instance.

// Request to build type
IRequestFor<Type> type = new TypeRequest(typeBuilder);
// Request to create new instance
IRequestFor<Object> newRequest = type.NewRequest();
// Get instance
object instance = service.GetRequired<IRequestFor<object>, object>(newRequest);
// Read with reflection
int value = (int)instance.GetType().GetField("MyField")!.GetValue(instance)!;
