我正在製作一個程序，該程序運行良好，除了我開始創建更新系統並以某種方式無法工作。啓動畫面使用webClient檢查更新，現在似乎也出現錯誤。我設置它以便啓動屏幕下載一個文本文件。如果版本不匹配，則單獨的表單將啓動並使用WebClient下載更新程序。我創建了這個表單兩次。它有1個progressBar，1個webClient，一個圖像背景和1個標籤。更新應該下載，在欄上顯示其進度，然後打開更新程序並關閉主程序。我第一次創建表單時，我運行它，它會凍結而不下載文件。在我停止調試之後，visual c＃express 2010的設計窗口會崩潰，我必須重新啓動vc＃。該窗口將顯示除了webClient以外我已添加的所有項目。所以我試着再次調試，我得到了這個消息：WebClient拋出「沒有數據可用於編碼1252」

所以我從窗體中刪除了webClient並重試。我第二次得到同樣的錯誤。所以我GOOGLE了第一個錯誤，並發現沒有修復hackforums一個響應。現在我完全失去了。我所有的Web客戶端似乎都在這樣做，我不知道爲什麼。
下面是從我的啓動畫面代碼：

下面是從我的更新代碼：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.Net;
namespace TubeRip
{
public partial class updates : Form
{
public updates()
{
InitializeComponent();
}
private void updates_Load(object sender, EventArgs e)
{
Uri update = new Uri("http://dl.dropbox.com/u/22054429/TubeRip_Installer.exe");
webClient1.DownloadFileAsync(update, "update.exe");
webClient1.DownloadProgressChanged +=new DownloadProgressChangedEventHandler(webClient1_DownloadProgressChanged);
webClient1.DownloadFileCompleted += new AsyncCompletedEventHandler(webClient1_DownloadFileCompleted);
}
void webClient1_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
{
Process.Start("update.exe");
Environment.Exit(0);
}
void webClient1_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
progressBar1.Value = e.ProgressPercentage;
label1.Text = "Downloading Updates Please Wait... " + e.ProgressPercentage.ToString() + "%";
}
}
}
沒有人可以幫助這個，所以我做了一些研究，並決定在webclient中使用UTF-8編碼，而不是拋出這個錯誤。 –
