我該如何更快更高效地做到這一點？

Question

我有這樣的代碼：

var url = "myurl.com/hwid.txt"; 
var client = new WebClient(); 
using (var stream = client.OpenRead(url)) 
using (var reader = new StreamReader(stream)) 
{ 
    string downloadedString; 
    while ((downloadedString = reader.ReadLine()) != null) 
    { 
    if (downloadedString == finalHWID) 
    { 
     update(); 
     allowedIn = true; 
    } 
    } 
    if (allowedIn == false) 
    { 
    MessageBox.Show("You are not allowed into the program!", name, 
        MessageBoxButtons.OK, MessageBoxIcon.Error); 
    } 

這將檢查你的HWID對那些允許的列表。但是，每次完成檢查時大約需要5-10秒。有沒有辦法讓它變得更快？

你可以做一個break一旦找到匹配：

var url = "myurl.com/hwid.txt"; 
var client = new WebClient(); 

using (var stream = client.OpenRead(url)) 
using (var reader = new StreamReader(stream)) 
{ 
    string downloadedString; 
    while ((downloadedString = reader.ReadLine()) != null) 
    { 
     if (downloadedString == finalHWID) 
     { 
      update(); 
      allowedIn = true; 
      break; 
     } 
    } 
} 

if (allowedIn == false) 
{ 
    MessageBox.Show("You are not allowed into the program!", name, MessageBoxButtons.OK, MessageBoxIcon.Error); 
}
