  To produce different sequences of random numbers, you can make the seed value time-dependent, thereby producing a different series with each new instance of <xref:System.Random>. The parameterized <xref:System.Random.%23ctor%28System.Int32%29> constructor can take an <xref:System.Int32> value based on the number of ticks in the current time, whereas the parameterless <xref:System.Random.%23ctor> constructor uses the system clock to generate its seed value. However, on the .NET Framework only, because the clock has finite resolution, using the parameterless constructor to create different <xref:System.Random> objects in close succession creates random number generators that produce identical sequences of random numbers. The following example illustrates how two <xref:System.Random> objects that are instantiated in close succession in a .NET Framework application generate an identical series of random numbers. On most Windows systems, <xref:System.Random> objects created within 15 milliseconds of one another are likely to have identical seed values.
