I am trying to use the c# mock callback for setting a value to a parameter that is a ref.
My code is something like that:
delegate void FooCallback(string p1, string p2, string p3, ref string p4, ref string p5, ref string p6, object p7);
public void TestMethod()
{
var parm1 = string.Empty;
var parm2 = string.Empty;
var parm3 = string.Empty;
var CallbackFunction = new FooCallback((string p1, string p2, string p3, ref string p4, ref string p5, ref string p6, object p7) => p5 = "value");
SomeServiceMock.Setup(x =>x.Foo(It.IsAny<string>(),
It.IsAny<string>(), It.IsAny<string>(), ref parm1, ref parm2, ref parm3,
It.IsAny<object>())).Callback(CallbackFunction);
}
But I get a compilation error saying that the Callback function can get only a parameter of type Action, and I can't just use Action because of the ref(or can I?) so how can I change the value of p5 when Foo is called?
I already tried everything from here
