    I am using CallMethod to call a private method and it works great, but I need to call a method that has some ref parameters, Is it possible to do that
    Also i would like to compare the values in the ref after the method execution finishes, basically instead of returning one value method is manipulating multiple values and i need to Assert all of them

    Hello Vikas,

    Here's how you can do it:
    public class HasRef
        private void Do(ref int a)
            a = a * 2;
    [TestMethod, TestCategory("Elevated"), TestCategory("NonPublic")]
    public void PrivateAccessor_RefCall()
        var inst = new PrivateAccessor(new HasRef());
        var args = new object[] { 20 };
        inst.CallMethod("Do", args);
        Assert.AreEqual(40, args[0]);

    Ref and out arguments are passed back into the array of arguments passed to CallMethod.
