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

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

        }

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

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

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