My situation is very simple. Somewhere in my code I have this:
dynamic myVariable = GetDataThatLooksVerySimilarButNotTheSame();
//How to do this?
if (myVariable.MyProperty.Exists)
//Do stuff
So, basically my question is how to check (without throwing an exception) that a certain property is available on my dynamic variable. I could do GetType()
but I'd rather avoid that since I don't really need to know the type of the object. All that I really want to know is whether a property (or method, if that makes life easier) is available. Any pointers?
I think there is no way to find out whether a dynamic
variable has a certain member without trying to access it, unless you re-implemented the way dynamic binding is handled in the C# compiler. Which would probably include a lot of guessing, because it is implementation-defined, according to the C# specification.
So you should actually try to access the member and catch an exception, if it fails:
dynamic myVariable = GetDataThatLooksVerySimilarButNotTheSame();
try
{
var x = myVariable.MyProperty;
// do stuff with x
}
catch (RuntimeBinderException)
{
// MyProperty doesn't exist
}
