How to filter a class properties collection?

Example: I have this class

public class MyClass
{
    private string propHead;
    private string PropHead { get; set; }

    private int prop01;
    private int Prop01 { get; set; }

    private string prop02;
    private string Prop02 { get; set; }

    // ... some more properties here

    private string propControl;
    private string PropControl { get; }  // always readonly
}

I need to exclude propHead and propControl. To exclude propControl:

MyClass mc = new MyClass();
PropertyInfo[] allProps = mc.GetType().GetProperties().Where(x => x.CanWrite).ToArray();

Now, how could I exclude propHead?, when all share same level of accesibility. Is there any way to add a special attribute to propHead that let me exclude it from the others. Properties names always is different in each class.

Any suggestions would be very apreciated.

This would be the easiest way:

MyClass mc = new MyClass();
PropertyInfo[] allProps = mc.GetType()
    .GetProperties()
    .Where(x => x.Name != "propHead" && x.Name != "propControl")
    .ToArray();

But if you're looking for a more general-purpose solution, you can try this

public class CustomAttribute : Attribute
{
    ...
}

MyClass mc = new MyClass();
PropertyInfo[] allProps = mc.GetType()
    .GetProperties()
    .Where(x => x.GetCustomAttributes(typeof(CustomAttribute)).Length > 0)
    .ToArray();
