Namespace:   System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public virtual int BlockSize { get; set; }

Property Value

Type: System.Int32

The block size, in bits.

Exception Condition

The block size is invalid.

The block size is the basic unit of data that can be encrypted or decrypted in one operation. Messages longer than the block size are handled as successive blocks; messages shorter than the block size must be padded with extra bits to reach the size of a block. Valid block sizes are determined by the symmetric algorithm used.
