Method for handling exceptions in mstest

Question

I have a lot of tests writen in this format:

[TestMethod]
public void TestMethod1()
{
    try
    {
        DoShomething();
    }
    catch (Exception e)
    {
        WriteExceptionLogWithScreenshot( e );
    }
}

[TestMethod]
public void TestMethod2()
{
    try
    {
        DoAnotherShomething();
    }
    catch ( Exception e )
    {
        WriteExceptionLogWithScreenshot( e );
    }
}

I would like to unify this exception handling using something like

[TestCleanup]
public void Cleanup()
{
    // find out if an exception was thrown and run WriteExceptionLogWithScreenshot( e )
}

Then I could avoid writing try catch blocks in all methods.

Does mstest support something like this? anyone have an ideia about what I could do?

This is simpler:

    private void TryTest(Action action)
    {
        try
        {
            action();
        }
        catch (Exception e)
        {
            WriteExceptionLogWithScreenshot(e);
            throw;
        }
    }

    [TestMethod]
    public void TestMethod1()
    {
        TryTest(new Action(() =>
        {
            DoSomething();
        }
        ));
    }

    [TestMethod]
    public void TestMethod2()
    {
        TryTest(new Action(() =>
        {
            DoAnotherSomething();
        }
        ));
    }

Be sure to re-throw the exception so the test fails. Notice the throw in the catch.
