How can I centralize modelstate validation in asp.net mvc using action filters?

Question

I write this code in several places and always repeat this logic:

public ActionResult MyMethod(MyModel collection)
{
    if (!ModelState.IsValid)
    {
              


        

Answer 1

public class ValidateModelStateAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext context)
    {
        if (!context.ModelState.IsValid)
        {              
            context.Result = new ViewResult();
        }
    }
}
