MemberInfoExtensions

Examples

MemberInfoExtensions provides extension methods for MemberInfo to check for the presence of one or more custom attributes via HasAttributes. This example defines a class with an [Description]-annotated property, an [Obsolete]-annotated field, and a regular property with no attributes, then iterates all public instance members calling HasAttributes with DescriptionAttribute and ObsoleteAttribute types. Console output shows each member name, its MemberType, and whether it carries any of the target attributes, demonstrating attribute-based filtering or validation of reflected members.

public class MemberInfoExtensionsExample
{
    [Description("Sample property with a DescriptionAttribute")]
    public string AnnotatedProperty { get; set; }

    [Obsolete("This field is obsolete.")]
    public string ObsoleteField;

    public string RegularProperty { get; set; }

    public static void Main()
    {
        var example = new MemberInfoExtensionsExample();
        var members = typeof(MemberInfoExtensionsExample).GetMembers(BindingFlags.Instance | BindingFlags.Public);

        foreach (MemberInfo member in members)
        {
            bool hasAttributes = member.HasAttributes(typeof(DescriptionAttribute), typeof(ObsoleteAttribute));
            Console.WriteLine($"{member.Name} ({member.MemberType}): has target attributes = {hasAttributes}");

}}
