UnicodeEncoding.GetString Method

Parameters

• bytes
  Type: array<System.Byte[]
  The byte array containing the sequence of bytes to decode.

• index
  Type: System.Int32
  The zero-based index of the first byte to decode.

• count
  Type: System.Int32
  The number of bytes to decode.

Return Value

Type: System.String
A string object that contains the results of decoding the specified sequence of bytes.
