Class TSRandom

A Thread Safe random class

Inheritance
Object
TSRandom
Namespace: SuperOffice.Util
Assembly: SoCore.dll
Syntax
public class TSRandom : Object
Remarks

https://andrewlock.net/building-a-thread-safe-random-implementation-for-dotnet-framework/
Dont initialize a new random for each invocation

  • makes for the same seed if called multiple times in a short time-span
  • resulting in same "random" output.

Random() is also not thread safe, keeping a static Random() per thread solves the problem of calling Random.Next() from several threads within 15 ms can give the same values multiple times.
