To find if particular url variable exists?

[Lauchlan M]

I'm retrieving url variable information uses the Request.QueryString object,
eg:

if (Request.QueryString.HasKeys())
key
{
lblMyResult.Text = Request.QueryString["myVar"];
}
else
{
lblMyResult.Text = "Var does not exist";
}

Request.QueryString.HasKeys() tells me if there are _any_ keys, how can I
find if one particular key exists (without cycling over all keys and
checking their names one by one)?

Thanks

if (Request.QueryString["MyVar"] != null)
