I am trying to make API calls to Amazon from my C# SDK. In this program, I deserialize a JSON string into C# objects and pass them as arguments into some methods to make API calls. The issue I have is the objects are not the same type with the arguments in the method signature. Below is my code. Pay attention to the "error" comments I make in the Main() method:
Here're the errors (I put these comments in my code above):
The classes I use in the above code can be viewed here:
ListingApi.cs: ListingApi.cs — Codefile
ListingsItemPatchRequest.cs: ListingsItemPatchRequest.cs — Codefile
PatchOperation.cs: PatchOperation.cs — Codefile
So the problem I have is the arguments I pass into the method are not the same type with the method's signature. How can I fixed them?
C#:
