JObject.JObjectDynamicProxy.TryInvokeMember

TryInvokeMember.cs

// Not sure if you'll like this at all, but adding this method to JObject.JObjectDynamicProxy
// allows us to use the invoked method as the default parameter, if the value does not exist.

// For example:

dynamic parsedObject = new JObject();
d.test = "Non-default option";
Console.WriteLine("Test is: " + d.test("Default Option"));

// Outputs:
// Test is: Non-default option

dynamic parsedObject = new JObject();
Console.WriteLine("Test is: " + d.test("Default Option"));
Console.WriteLine("Attempt 2: " + d.test);

// Outputs:
// Test is: Default Option
// Attempt 2: Default Option
