I personally agree with you both (I indeed didn't mention that), but personal preferences and thoughts on best practises in coding is not what he asked :), so the general statement that it's not possible is incorrect, but both of you are completely correct that you should avoid using it. (Revoted 5)

Exactly my idea.

You have literally reinvented the wheel from a well known existing method which works perfectly and you didn't add anything to it. Instead you made a less rigid solution.

This is basically string.Join only then not on the string, but on a list....

You are incorrect. Try this:
string[] arr = new[] {"item4", "test", "item 3", "item", "beer"};

int index = Array.IndexOf(arr, "item");
bool exists = Array.IndexOf(arr, "item") >= 0;

The returned index will always be 3 and if you remove "item", the index will be -1.

Voted 5 for this solution. Very elegant, I wouldn't have thought of that method :)

Better yet; just throw an exception. If it's unable to find a default mail client it should fail, because it's sole purpose is to determine the default mail client.

So I would make it:

public string getDefaultMailClient()
{
try
{
object mailClient = Registry.GetValue(
@"HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail", "", "none");
return mailClient.ToString();
}
catch (Exception exGetDefaultMailClient)
{
Util.EscribirLog(exGetDefaultMailClient.Message);
throw new Exception("Unable to determine default mail client", ex);
}
}

Here's a question: Why are interview questions so important in India? When they are answered all correctly you still have no clue whether person will fit in your team or even has enough knowledge, because they might as well just have read a book on .NET? In no other countries I see this kind of questionaires... So I hope you can enlighten me :)

Also, in addition to what the rest said, your questions are either too generic, specific or advocate bad practises. I would suggest to revise them.

Reinvention of the Stopwatch class.

While(true) is never a good practise in my opinion.
