// Create the class
[AttributeUsage(AttributeTargets.Class)] // Optionnaly you can restrict the usage of the attribute, see: https://learn.microsoft.com/fr-fr/dotnet/api/system.attributetargets
public class MyCustomAttribute: Attribute
{
    public string SomeProperty { get; set; }
}

// Use it
[MyCustomAttribute(SomeProperty = "foo bar")]
public class Foo
{
	// Your code
}

// To get the attribute you have set on your class, you need to use Reflection
MyCustomAttribute[] customAttributes = (MyCustomAttribute[])typeof(Foo).GetCustomAttributes(typeof(MyCustomAttribute), true);
if (customAttributes.Length > 0)
{
    MyCustomAttribute myAttribute = customAttributes[0];
    string value = myAttribute.SomeProperty;
    // TODO: Do something with the value
}
