Searching two column fields using asp.net mvc-CodePudding

I want to search using PersalNumber or IdNumber and it gave me an error that says:

No overload for method 'Where' takes 2 arguments

I have schema consisting of PersalNumber and IdNumber

PersalNumber stores a work number
IdNumber stores numbers of passport or driving license etc
Teachers is a table name

Below is the code I use for searching both the fields.

    public ActionResult PopulateResult(string search)
    {
        return View(db.teachers.Where(x=>x.PersalNumber.Contains(search), s=>s.IdNumber.Contains(search)).ToList());
    }

I want to know is there anything I am doing wrong here?

CodePudding user response：

You should adjust your condition like below

db.teachers.Where(x => x.PersalNumber.Contains(search) || 
                       x.IdNumber.Contains(search)).ToList();

CodePudding user response：

You need to use the || (or) operator between the two conditions.

return View(db.teachers.Where(x=>x.PersalNumber.Contains(search) ||  
                                 x.IdNumber.Contains(search)).ToList())

and you should make the comparison using the x argument not this undefined s
Note, this should work correctly if both PersonalNumber and IdNumber are strings.
