How to check whether SPList exists in SharePoint

Sometimes we require to check whether SPList exists or not. There is no direct method to check for it. Instead we have to use try-catch block to catch the exception and to determine the list existence:

The code is:

---

using (SPSite ospSite = new SPSite("http://<servername>:<portname>"))
{
using (SPWeb ospWeb = ospSite.OpenWeb())
{
try
{
SPList ospList = ospWeb.Lists["ListName"];
if (ospList != null)
return true;
}
catch(Exception ex)
{
return false;
}
}
}
