C# 0 The Complete Reference

BitArray

 defines 

the methods shown in Table 24-9. Notice that 

BitArray

 does not supply a 

Synchronized( )

method. Thus, a synchronized wrapper is not available, and the 

IsSynchronized

 property is 

always false. However, you can control access to a 

BitArray

 by synchronizing on the object 

provided by 

SyncRoot

.

Method

Description

public BitArray And(BitArray 

ba

)

ANDs the bits of the invoking object with those specified by 

ba

and returns a

 that contains the result.

public bool Get(int 

idx

)

Returns the value of the bit at the index specified by 

idx.

public BitArray Not( )

Per forms a bitwise, logical NOT on the invoking collection and 

returns a 

BitArray

 that contains the result.

public BitArray Or(BitArray 

ba

ba

and returns a 

BitArray

 that contains the result.

public void Set(int 

idx

, bool 

v

)

Sets the bit at the index specified by 

idx

 to 

v.
