Summary: Evaluating Non-Defined Conditions
Initial Comment:
Session.Evaluatecondition throws an exception if passed a null. This can be
prevented by checking for string.IsNullOrEmpty prior to calling the method but
I'm wondering that since an empty condition in Windows Installer evaluates to
TRUE that perhaps it might be simpler for developers consuming the method if
the method simply returned true if passed an empty argument.
Just a thought.
System.ArgumentNullException: Value cannot be null.
Parameter name: condition
at Microsoft.Deployment.WindowsInstaller.Session.EvaluateCondition(String
condition)
if (
string.IsNullOrEmpty( condition ) || session.EvaluateCondition(condition)
== true)
