UnicodeEncoding.GetBytes Method (Char*, Int32, Byte*, Int32)
Assembly: mscorlib (in mscorlib.dll)
[CLSCompliantAttribute(false)] [ComVisibleAttribute(false)] public override int GetBytes ( char* chars, int charCount, byte* bytes, int byteCount )
A pointer to the first character to encode.
The number of characters to encode.
A pointer to the location at which to start writing the resulting sequence of bytes.
The maximum number of bytes to write.
Return ValueThe actual number of bytes written at the location indicated by the bytes parameter.
chars is a null reference (Nothing in Visual Basic).
bytes is a null reference (Nothing in Visual Basic).
charCount or byteCount is less than zero.
Error detection is enabled, and chars contains an invalid sequence of characters.
byteCount is less than the resulting number of bytes.
To calculate the exact array size that GetBytes requires to store the resulting bytes, use GetByteCount. To calculate the maximum array size, use GetMaxByteCount. The GetByteCount method generally allows you to allocate less memory, whereas the GetMaxByteCount method generally executes faster.
With error detection, an invalid sequence causes this method to throw an ArgumentException. Without error detection, invalid sequences are ignored, and no exception is thrown.
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, use the Decoder or the Encoder object provided by the GetDecoder or the GetEncoder method, respectively.
To ensure that the encoded bytes are decoded properly, prefix encoded bytes with a preamble.
