示例1: getBytes
//Metodo para conversion de imagenes de tipo BLOB a array de bytes
public static byte[] getBytes(int columna,SqliteDataReader reader)
{
const int CHUNK_SIZE = 2 * 1024;
byte[] buffer = new byte[CHUNK_SIZE];
long bytesRead;
long fieldOffset = 0;
int bufferoffset = 0;
using (MemoryStream stream = new MemoryStream())
{
while ((bytesRead = reader.GetBytes(columna, fieldOffset, buffer, bufferoffset, buffer.Length)) > 0)
{
stream.Write(buffer, 0, (int)bytesRead);
fieldOffset += bytesRead;
}
return stream.ToArray();
}
}示例2: GetBytes
private static byte[] GetBytes(SQLiteDataReader reader)
{
const int CHUNK_SIZE = 2 * 1024;
byte[] buffer = new byte[CHUNK_SIZE];
long bytesRead;
long fieldOffset = 0;
using (MemoryStream stream = new MemoryStream())
{
while ((bytesRead = reader.GetBytes(0, fieldOffset, buffer, 0, buffer.Length)) > 0)
{
byte[] actualRead = new byte[bytesRead];
Buffer.BlockCopy(buffer, 0, actualRead, 0, (int)bytesRead);
stream.Write(actualRead, 0, actualRead.Length);
fieldOffset += bytesRead;
}
return stream.ToArray();
}
}示例3: ReadBinaryBlob
static int ReadBinaryBlob(SqliteDataReader reader, int column, ref byte[] buffer)
{
long nread;
// first, get the length of the buffer needed
if ((nread = reader.GetBytes (column, 0, null, 0, buffer.Length)) > buffer.Length)
Array.Resize (ref buffer, (int) nread);
// read the certificate data
return (int) reader.GetBytes (column, 0, buffer, 0, (int) nread);
