Check if a property exists in a class

Question

I try to know if a property exist in a class, I tried this :

public static bool HasProperty(this object obj, string propertyName)
{
    return obj.GetType().

This answers a different question:

If trying to figure out if an OBJECT (not class) has a property,

OBJECT.GetType().GetProperty("PROPERTY") != null

returns true if (but not only if) the property exists.

In my case, I was in an ASP.NET MVC Partial View and wanted to render something if either the property did not exist, or the property (boolean) was true.

@if ((Model.GetType().GetProperty("AddTimeoffBlackouts") == null) ||
        Model.AddTimeoffBlackouts)

helped me here.

Edit: Nowadays, it's probably smart to use the nameof operator instead of the stringified property name.
