c# - ModelState validation checking multiple boolean property -

i have view model have multiple boolean properties, in controller have checking modelstate.isvalid before proceeding service layer. want create modelstate.isvalid homecoming false if none of boolean property set true, there way create happen?

here sample class

public class role { public int id {get; set;} [required(errormessage = "please come in role name")] public string name {get; set;} public bool iscreator {get; set;} public bool iseditor {get; set;} public bool ispublisher {get; set;} }

i implement own validation method on model. model end looking this:

public class role : ivalidatableobject { public int id {get; set;} [required(errormessage = "please come in role name")] public string name {get; set;} public bool iscreator {get; set;} public bool iseditor {get; set;} public bool ispublisher {get; set;} public ienumerable<validationresult> validate(validationcontext validationcontext) { if (!this.iscreator && !this.iseditor && !this.ispublisher)) { yield homecoming new validationresult("you must creator, editor or publisher"); } } }

notice how model:

implements ivalidateableobject has method named validate returns type ienumerable<validationresult>

during model binding process method automatically called , if validation result returned modelstate no longer valid. using familiar code in controller create sure don't take action unless custom conditions check out:

public class somecontroller { public actionresult someaction() { if (modelstate.isvalid) { //do stuff! } } }
