Encoding.GetString Method (Byte[], Int32, Int32)
Assembly: mscorlib (in mscorlib.dll)
public String GetString ( byte[] bytes, int index, int count )
public function GetString ( bytes : byte[], index : int, count : int ) : String
Not applicable.
Parameters
- bytes
The byte array containing the sequence of bytes to decode.
- index
The index of the first byte to decode.
- count
The number of bytes to decode.
Return Value
A String containing the results of decoding the specified sequence of bytes.| Exception type | Condition |
|---|---|
| bytes is a null reference (Nothing in Visual Basic). | |
| index or count is less than zero. -or- index and count do not denote a valid range in bytes. | |
| A fallback occurred (see Understanding Encodings for complete explanation) -and- DecoderFallback is set to DecoderExceptionFallback. |
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, the application should use the Decoder or the Encoder provided by the GetDecoder method or the GetEncoder method, respectively, of a derived class.
The following code example demonstrates how to read a UTF-8 encoded string from a binary file.
private: String^ ReadAuthor( Stream^ binary_file ) { System::Text::Encoding^ encoding = System::Text::Encoding::UTF8; // Read string from binary file with UTF8 encoding array<Byte>^ buffer = gcnew array<Byte>(30); binary_file->Read( buffer, 0, 30 ); return encoding->GetString( buffer ); }
private String ReadAuthor(Stream binary_file)
{
System.Text.Encoding encoding = System.Text.Encoding.get_UTF8();
// Read string from binary file with UTF8 encoding
ubyte buffer[] = new ubyte[30];
binary_file.Read(buffer, 0, 30);
return encoding.GetString(buffer);
} //ReadAuthor
