Question

I’ve asked a similar question before but I’m just having a hard time wrapping my head around this…

I have a delegate…

delegate void assertDelegate(params object[] args);

and I have a method that invokes the delegate…

public void assert(assertDelegate assertMethod, params object[] args) {
        string expectedValue;
        string actualValue;
        // derive value of 'expectedValue' and 'actualValue' from 'args'
        assertMethod.DynamicInvoke(expectedValue, actualValue);
    }

my thought was that there has to be a way to pass the action and dynamically invoke the arguments for that action…

assert(Assert.AreEqual,new object[]{ HtmlDiv.PropertyNames.Id, "footer"});

but I’m getting the error Expected a method with 'void AreEqual(params object[])' signature.

Perhaps I’m misunderstanding DynamicInvoke?

Answer 1

delegate void assertDelegate(params object[] args);

This delegate signature does not match any signature of Assert.AreEqual.
Use instead:

delegate void assertDelegate(string first, string second);

Or a Func<string, string>.
