How to get the latest version lable of a file

Some time it is required just to know the what was the last version of the file saved in the version enabled document library.



public Double getLastVersion(string flname, bool tt)
{
string doclibname = ConfigurationManager.AppSettings["doclibname"].ToString();
Double ver = 0;
//get the latest version
using (SPSite objSite = SPContext.Current.Site)
{
using (SPWeb objWeb = objSite.OpenWeb())
{
SPFolder mylibrary = objWeb.Folders[doclibname];
foreach (SPFile file in mylibrary.Files)
{
if (file.Name.ToString() == flname+ ".doc")
{
ver = System.Convert.ToDouble(file.UIVersionLabel);
Break;
}
}
return ver;

}
}
}
