Encoding.GetString Method (Byte)
When overridden in a derived class, decodes all the bytes in the specified byte array into a string.
Assembly: mscorlib (in mscorlib.dll)
abstract GetString : bytes:byte -> string override GetString : bytes:byte -> string
- Type: System.Byte
The byte array containing the sequence of bytes to decode.
Return ValueType: System.String
A string that contains the results of decoding the specified sequence of bytes.
The byte array contains invalid Unicode code points.
bytes is a null reference (Nothing in Visual Basic).
A fallback occurred (see Character Encoding in the .NET Framework for complete explanation)
If the data to be converted is available only in sequential blocks (such as data read from a stream) or if the amount of data is so large that it needs to be divided into smaller blocks, you should use the Decoder object returned by the GetDecoder method of a derived class.
See the Remarks section of the Encoding.GetChars reference topic for a discussion of decoding techniques and considerations.
Note that the precise behavior of the GetString method for a particular Encoding implementation depends on the fallback strategy defined for that Encoding object. For more information, see the "Choosing a Fallback Strategy" section of the Character Encoding in the .NET Framework topic.
The following example reads a UTF-8 encoded string from a binary file represented by a FileStream object. For files that are smaller than 2,048 bytes, it reads the contents of the entire file into a byte array and calls the method to perform the decoding. For larger files, it reads 2,048 bytes at a time into a byte array, calls the Decoder.GetCharCount(Byte, Int32, Int32) method to determine how many characters are contained in the array, and then calls the Decoder.GetChars(Byte, Int32, Int32, Char, Int32) method to perform the decoding.
The example uses the following text, which should be saved to a UTF-8 encoded file named Utf8Example.txt.
This is a UTF-8-encoded file that contains primarily Latin text, although it does list the first twelve letters of the Russian (Cyrillic) alphabet: А б в г д е ё ж з и й к The goal is to save this file, then open and decode it as a binary stream.
