Question

I have some code that performs a query.

int credenciadaId = 10;
var nome = from c in db.SanCredenciadas
           where c.CredenciadaId == credenciadaId
           select c.Name;

My question is in 2 parts.

I want the query to return just one Name as a string. How can I change the query nome so the following code would be valid?

string name = nome;

Additionally, how can I write the improved query so that it uses lambda expression(s) and the method syntax rather than the current query syntax?

Answer 1

like this

string name = nome.Single().Name;

This will fail if you don’t get one result which I suspect is what you want.

Your query using a lambda would be

var credenciadaId = 10;
var name = db.San_Credenciadas
    .Single(c => c.Credenciada_Id == credenciadaId).Name;
