Question

The problem I am having is that I would like to call a method from a string. Here is what I am doing:

Building My List of Strings (Methods) there are three different checkboxList objects in my UI

private List<string> MyTest = new List<string>();
private void AddSelectedMethods()
{
        foreach(XName item in BaseTestList.CheckedItems)
        {
            MyTests.Add(item.ToString());
        }
        foreach (XName item in AdminTestList.CheckedItems)
        {
            MyTests.Add(item.ToString());
        }
        foreach (XName item in SubscriberTestList.CheckedItems)
        {
            MyTests.Add(item.ToString());
        }
}

Here is the Caller. If I take out the Reflections call and reference the method directly everything works but I don’t want to get into crating a huge list of if else statements.

    private void StartSiteTest(object sender, DoWorkEventArgs e)
    {
        if (!BackWorker1.CancellationPending)
        {
            if (SiteToTest == "estatesales.vintagesoftware.local" || SiteToTest == "localhost")
            {
                es = new EstateSaleTests(site, Sites.First(i => i.SiteUrl == SiteToTest), BasePath, SiteToTest, UseCurrentCompanies);
                foreach (string test in MyTests)
                {

                    // <<<!!!!!!!!  ------ The next line returns null ------ !!!!!!!>>>
                    MethodInfo thisMethod = es.GetType().GetMethod(test);

                    thisMethod.Invoke(es, null);
                }
            }
        }
    }

Any help on what I am doing wrong would be greatly appreciated.

!!!—– EDIT —–!!!

I’m an idiot. I had the class set to the list of strings but I forgot to rename my Methods Sorry about that. Yes the Methods were public and they are accessible I just have to rename them to the correct names now.

The call you use seems pretty acceptable, imo.
The thing is that GetType().GetMethod() is able to recover only public methods.

See this MSDN link.

In order to access methods with different acessors use this GetMethod(string, BindingFlags) overload.

Hope this helps.
