Parsing With SPFieldUserValue With Extension Methods

When using SPFieldUserValue to hydrate properties like SPFieldUserValue.Login, it is best to use consistent extension methods as demonstrated below:

public static string GetUserLogin(this SPListItem item, string fieldName)
{
var userValue = new SPFieldUserValue(item.Web, (string) item[fieldName]);
return userValue.User != null ? userValue.User.LoginName : string.Empty;
}
