How to know if some method can throw an exception

I'm new in a developement for Windows 8 and C#, but I have certain experience with Java Programming. So, when I try to make some Json parser (for example) in java, I can't do it without use a try - catch block, and this way I can handle the exception, but when I try to do the same in c# (Windows 8) and I don't use the try - catch block it works too, like this: ``` if (json != null) { JObject jObject = JObject.Parse(json); JArray jArrayUsers = (JArray)jObject["users"]; foreach (JObject obj in jArrayUsers) { ListViewMainViewModel user = new ListViewMainViewModel( (String)obj["email"], (String)obj["token"], (String)obj["institution"], (String)obj["uuidInstitution"]); usersList.Add(user); } return usersList; } } ``` As I know the right way is to catch JsonReaderException, but Visual Studio never warned me on that. I would like to know if there's a easy way to know if some method throw an exception, like is on java using eclipse (it's mandatory implement try-catch block or code wont compile)
