OSDMap map = new OSDMap(); map.Add("key1", new OSDString("value1")); OSDString value; bool result = map.TryGetValue("key1", out value); if (result) { Console.WriteLine("The value of 'key1' is " + value); } else { Console.WriteLine("The key 'key1' was not found in the map."); }In this example, we create a new OSDMap object, add a key-value pair to it, and then use TryGetValue to retrieve the value associated with the "key1" key. Because "key1" is found in the map, the method returns true and the value of "value" is set to "value1", which is then printed to the console. The package library for OSDMap is part of the OpenMetaverse package, which is a set of C# libraries for working with virtual worlds such as Second Life.
