ASP.NET MVC - Alternative for [Bind(Exclude = “Id”)]

Question

Is there an alternative for [Bind(Exclude = \"Id\")] (Related Question) ?

Could I write a model binder?

Answer 1

As Desmond stated, I find remove very easy to use, also I've made a simple extension which can come in handy for multiple props to be ignored...

    /// 

    /// Excludes the list of model properties from model validation.
    /// 
    /// The model state dictionary which holds the state of model data being interpreted.
    /// A string array of delimited string property names of the model to be excluded from the model state validation.
    public static void Remove(this ModelStateDictionary ModelState, params string[] modelProperties)
    {
        foreach (var prop in modelProperties)
            ModelState.Remove(prop);
    }

You can use it like this in your action method:

    ModelState.Remove(nameof(obj.ID), nameof(obj.Prop2), nameof(obj.Prop3), nameof(obj.Etc));
