如何将存储在我的数据库字段中的二进制数据转换为Byte []数组?将二进制转换为字节[] array
简单铸造二进制为字节[]不工作
context.Response.BinaryWrite((byte[])images);

如果图像是二进制类型的单个记录,然后调用指定者应该工作
context.Response.BinaryWrite(images.toArray());
public byte[] FileToByteArray(string _FileName)
{
byte[] _Buffer = null;
try
{
// Open file for reading
System.IO.FileStream _FileStream = new System.IO.FileStream(_FileName, System.IO.FileMode.Open, System.IO.FileAccess.Read);
// attach filestream to binary reader
System.IO.BinaryReader _BinaryReader = new System.IO.BinaryReader(_FileStream);
// get total byte length of the file
long _TotalBytes = new System.IO.FileInfo(_FileName).Length;
// read entire file into buffer
_Buffer = _BinaryReader.ReadBytes((Int32)_TotalBytes);
// close file reader
_FileStream.Close();
_FileStream.Dispose();
_BinaryReader.Close();
}
catch (Exception _Exception)
{
// Error
Console.WriteLine("Exception caught in process: {0}", _Exception.ToString());
}
return _Buffer;
}
