Convert anonymous type to new C# 7 tuple type

Question

The new version of C# is there, with the useful new feature Tuple Types:

public IQueryable Query();

public (int id, string name) GetSomeIn         


        

Answer 1

Of course, by creating the tuple from your LINQ expression:

public (int id, string name) GetSomeInfo() {
    var obj = Query()
        .Select(o => (o.Id,o.Name))
        .First();

    return obj;
}

According to another answer regarding pre-C# 7 tuples, you can use AsEnumerable() to prevent EF to mix things up. (I have not much experience with EF, but this should do:)

public (int id, string name) GetSomeInfo() {
    var obj = Query()
        .AsEnumerable()
        .Select(o => (o.Id,o.Name))
        .First();

    return obj;
}
