As title, found that the parameters of controller, if the user doesn't pass this parameter, program error directly, not to give any judgment return errors, how to do,

For instance I this public ActionResult HouseTypeInfo (int houseid, int the typeid)

Users don't preach houseid error directly, don't give me any judge disposal way,

Please people!

CodePudding user response:

That is what happened to the front, don't mind

CodePudding user response:

This
Public ActionResult HouseTypeInfo (int? Houseid, int? Typeid)

Then use hasvalue to judgment,
