我正在写一个小的C#程序哈希哈希。我想它做的两件事情(有点像基准):(基准)无止境的循环没有冻结线程
hash = md5.ComputeHash(hash);
tell me how many times per second it can do this.
目前,我有一个计时器与OnTimedEvent跟踪多少哈希通过每秒来无限,而(真)环保持哈希。一旦哈希开始,我的程序和定时器就会被冻结。
这样做的正确方法是什么?我怎样才能保持散列(并输出)而不会冻结?
提前致谢!

此时一切除计时器Quiete酒店线性。
public partial class Form1 : Form
{
private int count;
private MD5 md5;
private byte[] hash;
private bool Calculate = false;
private System.Timers.Timer timer;
public Form1()
{
InitializeComponent();
count = 0;
PrepareFirstHash();
timer = new System.Timers.Timer(1000);
timer.Elapsed += OnTimedEvent;
timer.Enabled = true;
}
private void PrepareFirstHash()
{
md5 = MD5.Create();
byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes("start");
hash = md5.ComputeHash(inputBytes);
}
private void DoCalc()
{
hash = md5.ComputeHash(hash);
count++;
}
private void OnTimedEvent(Object source, ElapsedEventArgs e)
{
SetText(count.ToString());
count = 0;
}
delegate void SetTextCallback(string text);
private void SetText(string text)
{
if (this.label1.InvokeRequired)
{
SetTextCallback d = new SetTextCallback(SetText);
this.Invoke(d, new object[] { text });
}
else
{
this.label1.Text = text;
}
}
private void btnStart_Click(object sender, EventArgs e)
{
Calculate = true;
while (Calculate){
DoCalc();
}
}
private void btnStop_Click(object sender, EventArgs e)
{
Calculate = false;
}
}
}
听起来像是'BackgroundWorker'工作。请参阅http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx – Vlad 2014-09-22 21:59:17
如果您只是计时一种方法,为什么不使用控制台应用程序和'System.Diagnostics。 Stopwatch'? – 2014-09-22 22:04:06
