Exclude property from getType().GetProperties()

Question

Hi i\'m working in a class library using C#, and i have some classes with some properties.

I just wanna know if i can add something to exclude some properties form t

You could put a custom attribute on your type.

public class DoNotIncludeAttribute : Attribute
{
}

public static class ExtensionsOfPropertyInfo
{
    public static IEnumerable GetAttributes(this PropertyInfo propertyInfo) where T : Attribute
    {
        return propertyInfo.GetCustomAttributes(typeof(T), true).Cast();
    }
    public static bool IsMarkedWith(this PropertyInfo propertyInfo) where T : Attribute
    {
        return property.GetAttributes().Any();
    }
}
public class Test
{
    public string One { get; set; }

    [DoNotInclude]
    public string Two { get; set; }
}

Then, in your runtime, you can search for properties that are not hidden.

foreach (var property in properties.Where(p => !p.IsMarkedWith())
{
    // do something...
}

It won't be really hidden, but it wouldn't show up in the enumeration.
