It looks like the string contains an array with a single MyStok object in it. If you remove square brackets from both ends of the input, you should be able to deserialize the data as a single object:

MyStok myobj = JSON.Deserialize<MyStok>(sc.Substring(1, sc.Length-2));

You could also deserialize the array into a list of MyStok objects, and take the object at index zero.

var myobjList = JSON.Deserialize<List<MyStok>>(sc);
var myObj = myobjList[0];

I ran into this exact same error message   I tried Aditi s example  and then I realized what the real issue was    Because I had another apiEndpoint making a similar call that worked fine    In this case The object in my list had not had an interface extracted from it yet   So because I apparently missed a step  when it went to do the bind to the List lt OfthisModelType gt   It failed to deserialize  If you see this issue  check to see if that could be the issue
