Learning to use ASP. NET's system. Collections. bitarray class

Common members:

 
/* Attribute */count // read-only length // same as count, but can read/write/* Method */and () // and get () // value not () // returns the reverse or () // or set () // value setall () // All is set to the specified value XOR () // returns or
