DaysLeft(bool)

Returns the number of days left for a given license (time left). This method is particularly useful when KeyInfo is not updated regularly, because TimeLeft will not be affected (stay constant). If your implementation checks the license with the server periodically, this method should be used instead of TimeLeft.

Declaration
public int DaysLeft(bool zeroIfExpired = false)
Parameters
Type Name Description
bool zeroIfExpired

If true, when a license has expired, zero will be returned.
Returns
Type Description
int
