plz help me in generating 5 unique random number between 0 to 8

推荐答案

这是关于System.Random的信息，请参见http://msdn.microsoft.com/en-us/library/system.random.aspx [System.Collection.Generic.Dictionary)中；每次检查新添加的值是否已经在字典中.如果已经存在，请重试(如果未添加).

This is about System.Random, see http://msdn.microsoft.com/en-us/library/system.random.aspx[^]. Don''t repeat a common mistake, the instance of this class only once (per application domain per runtime).

What means "unique"? Does it mean all 5 should be different? In this case, put all generated values in dictionary (System.Collection.Generic.Dictionary); each time check up if the newly added value is already in dictionary. If it is already there, try again, if not add it.
