GetBytes(Int32, Byte[], Int32, Int32)
Retrieves a specified number of bytes of raw binary data.
public:
abstract int GetBytes(int index, cli::array <System::Byte> ^ buffer, int bufferIndex, int length);public abstract int GetBytes (int index, byte[] buffer, int bufferIndex, int length);abstract member GetBytes : int * byte[] * int * int -> intPublic MustOverride Function GetBytes (index As Integer, buffer As Byte(), bufferIndex As Integer, length As Integer) As IntegerParameters
- index
- Int32
Index in the current block of data for the item to retrieve.
- buffer
- Byte[]
An array into which specified data, as a byte array, should be placed. If null, this method returns the size required of the array in order to fit all of the specified data.
- bufferIndex
- Int32
The index of the starting point in the byte array specified in the buffer parameter.
- length
- Int32
The number of bytes to be read into the byte array specified in the buffer parameter.
Returns
An integer value indicating the number of bytes read into the buffer.
Implements
Exceptions
The index, bufferIndex, and/or length parameters are invalid.
Applies to
