c# - Random number generator always picks the same value …

WebThe point in the sequence where a particular run of pseudo-random values begins is selected using an integer called the seed value. The seed is normally set from some arbitrary value like the system clock before the random number functions are used. This prevents the same run of values from occurring each time a game is played and thus … WebIf two tasks created after each other generate the same random value in C#, it is likely due to the fact that the default seed value for the Random class is based on the system clock, which has a limited resolution. Since the two tasks were created in quick succession, their system clock seed values are likely to be the same, resulting in the same sequence of … bai zhong
