How do I tell if a class property has a public set (.NET)?

Question

I have this:

public string Log
        {
            get { return log; }
            protected set
            {
                if (log != value)
                {
                    MarkModified(PropertyNames.Log, log);
                    log = value;
                }
            }

        }

And my utility class for databinding does this:

PropertyInfo pi = ReflectionHelper.GetPropertyInfo(boundObjectType, sourceProperty);

if (!pi.CanWrite)
                SetReadOnlyCharacteristics(boundEditor);

But PropertyInfo.CanWrite does not care whether the set is publicly accessible, only that it exists.

How can I determine if there's a public set, not just any set?

Answer 1

You need to use the BindingFlags. Something like

PropertyInfo property = type.GetProperty("MyProperty", BindingFlags.Public | BindingFlags.SetProperty | BindingFlags.Instance);

Answer 2

An alternative to the suggested changes to ReflectionHelper in other answers is to call pi.GetSetMethod(false) and see if the result is null.

Answer 3

Call GetSetMethod on PropertyInfo, obtain MethodInfo and examine its properties, like IsPublic.
