The following example shows how to use the TimeStampAttribute in a persistent class.
C#Copy Code
             [Persistent("USER")] 
public class User 
{ 
    // ... Other code of the class. 
 
    [TimeStamp] 
                    [Field("TIME_STAMP")] 
    public string TimeStamp 
    { 
        // ... code of the property.

Remarks

The TimeStampAttribute is used to connect a member of the persistent class with a field of the storage. The property is used as time stamp property for the TimeStampConcurrencyManager. Every time and update is performed the time stamp is checked of being changed. If the stamp changed the object was modified by somebody else in the mean time (in the time being in memory).
