c# - How to serialize System.Diagnostics.Stopwatch -

I have a class named [serializable] in which the system is located. Diagnostics However, I can not serialize the class by using BinaryFormatter due to System.Diagnostics.Stopwatch. Is there a way to mark or make System.Diagnostics.Stopwatch serializable?

After

You can create a SerializationSurrogate and a surrogate selector for a stopwatch.

Be careful that the stopwatch class may have machine-specific status, i.e. tick frequency and so on. So, when you order in order, check the serialization reference that the sequence is not intended for the use of cross machine (if you intend to copy all the values), or you can create a completely new example with only time data.

Binterformor Formatter = New System From time to time. Serialization.formatars.binary.binterformer (); // Create a format elsewhere (if the formatter.SurrogateSelector == faucet) {formatter.SurrogateSelector = new StopWatchSelector (); } And {formatter.SurrogateSelector.ChainSelector (new StopWatchSelector ()); } {Formatter.Serialize (stream, container) by using System.IO.MemoryStream stream = new system.OO.MemoryStream ()); Stream.Flush (); section. Composition = 0; Copy = formatter.Deserialize (stream) as container; } System.Diagnostics.Debug.WriteLine ("Reference equals:" + (Object. Reference Aqualls (Container, Copy)).
