Private Extension Methods - Null Parameter

Hi,

I am not sure about the implementation of SomeFunction, but I'll show an example of how to invoke an extension method using Invoke API.

[TestMethod]
public void test()
{
    var someClass = new SomeClass();
    
    bool result = (bool)Isolate.Invoke.Method(typeof(SomeClassExtensions), "SomeFunction", someClass);
    
    Assert.IsTrue(result);
}

Where the extension method is:

public static class SomeClassExtensions
{
    public static bool SomeFunction(this SomeClass someClass)
    {
        return true;
    }
}

The invocation is performed on the extension method class and the argument sent is the object itself. In this example:

Isolate.Invoke.Method(
   typeof(SomeClassExtensions), // The extension methods class
   "SomeFunction", // The extension method name
   someClass) // The object on which the method needs to be invoked

Please let me know if it helps.

Elisha,

What you have is essentially what I have... My problem is that if you make the call:

Isolate.Invoke.Method(
   typeof(SomeClassExtensions), // The extension methods class
   "SomeFunction", // The extension method name
   null) // The object on which the method needs to be invoked

where you pass null in instead of someClass, then typemock throws an exception. Passing null into an extension method is supported in .Net framework.

Squid,

This seems like a bug then. We query the instance that is passed to the extension method, and do not handle null properly. This will be fixed in a future version.

Thanks,

Did you try to use Reflection instead of Typemock?
