Question

How can I set the value of a variable inside an IronPython scope to None from C# using ScriptScope.SetVariable without using ScriptEngine.ExecuteAndWrap("x = None", scope)? Does the variable need to already be defined within the ScriptEngine/ScriptScope? This example did not work:

// Note: "scope" is the ScriptScope variable assigned beforehand

scope.SetVariable("x", null);

web search found this related link but it did not provide a solution:

As far as I know the keyword object is just an alias for System.Object, but I found that casting null to System.Object worked in some cases.

scope.SetVariable("x", (Object)null);
