validation - Validate an Object in ASP.NET MVC without passing it into an Action -

in asp.net mvc can validate model passed action modelstate.isvalid().

i'd validate arbitrary objects rather 1 model passed in. how can that, using framework's libraries?

public actionresult isvalidsofar() {     // user's autosaved data     var json = await ...     homemodel model = jsonconvert.deserialize<homemodel>(json);      // validate model <---- how?         }  public class homemodel {     [required, maxlength(100)]     public string name { get; set; } } 

you can use validationcontext class ... below

var context = new validationcontext(modelobject);     var results = new list<validationresult>();     var isvalid = validator.tryvalidateobject(modelobject, context, results);      if (!isvalid)     {         foreach (var validationresult in results)         {             //validation errors         }     }
