How do I structure a class or a function/method (or interface) so that as part of a using, I can pass values in the {} brackets?

Question

in the following:

using (var something = new SomeFunction(somevalue) { AnotherValue = anotherValue, AdditionalValue = adValue })

Your class has to inherit from `IDisposable` this way you can use `using`. The `{}` can be used with public properties. — Christoph K, Jan 29 '16 at 12:34

Using the brackets {} you can set the public properties of that object after the constructor finished.

AnotherValue and AdditionalValue are properties of SomeFunction

It is called object initializers.

Yours is technically right and thank you, i'm accepting romanoza's as the answer because he provided code that I could use as is. I did not know they were called initializers.. I wish i could accept both of your answers because the two answers combined = the full answer. – Kevin Scheidt Feb 01 '16 at 19:58

You code is completely valid. You can write your use clause as:

public class SomeClass: IDisposable
{
    public SomeClass(object somevalue) {
    }

    public int AnotherValue { get; set; }

    public int AdditionalValue { get; set; }

    internal void ImHere() {
        throw new NotImplementedException();
    }

    public void Dispose() {
        throw new NotImplementedException();
    }
}

static void Main(string[] args) {
    object somevalue = null;
    using (var something = new SomeClass(somevalue) { AnotherValue = 1, AdditionalValue = 2 }) {
        something.ImHere();
    }
}
