示例1: Calculate
public static string Calculate(string path, HashType hashType, Action<int> callBack, CancellationToken token)
{
var hashAlgorithm = hashType.GetAlgorithm();
// 64 kb
const int STREAM_BUFFER_SIZE = 4096 * 16;
const int HASH_BUFFER_SIZE = 4096;
var buffer = new byte[HASH_BUFFER_SIZE];
var lastPercent = -1;
using (var fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read, STREAM_BUFFER_SIZE))
{
var fileSize = fs.Length;
long readed = 0;
while (true)
{
if (token.IsCancellationRequested)
return null;
var len = fs.Read(buffer, 0, buffer.Length);
if (readed + HASH_BUFFER_SIZE >= fileSize)
{
hashAlgorithm.TransformFinalBlock(buffer, 0, len);
return GetStringFromBytes(hashAlgorithm.Hash);
}
var handler = callBack;
if (handler != null)
{
var percent = (int)(100 * (readed / (float)fileSize));
