我的应用程序从Web服务器下载JSON文件（json.html）并将文件保存在IsolatedStorage上。这段代码工作正常。
所以，我需要从同一个Web服务器下载，但需要更多文件（“json.html”，“json1.html”和“json2.html”）并保存在IsolatedStore上。
如何使代码适应更多文件？
该文件必须与Web服务器中的文件同名保存（如我的代码所示）。
我的代码：
private void sinc(object sender, EventArgs e)
{
IsolatedStorageSettings iso = IsolatedStorageSettings.ApplicationSettings;
if (iso.TryGetValue<string>("isoServer", out retornaNome))
{
serv = retornaNome;
}
else {
MessageBox.Show("Configure um servidor antes de sincronizar os dados!");
return;
}
order.Visibility = Visibility.Collapsed;
client = new WebClient();
url = serv + "/json.html";
Uri uri = new Uri(url, UriKind.RelativeOrAbsolute);
client.OpenReadCompleted += new OpenReadCompletedEventHandler(client_OpenReadCompleted);
client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged);
client.OpenReadAsync(uri);
}
private void client_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
string strFileName = url.Substring(url.LastIndexOf("/") + 1, (url.Length - url.LastIndexOf("/") - 1));
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
// Path Storage
// *** If File Exists
if (isoStore.FileExists(strFileName))
{
isoStore.DeleteFile(strFileName);
}
IsolatedStorageFileStream dataFile = new IsolatedStorageFileStream(strFileName, FileMode.CreateNew, isoStore);
long fileLen = e.Result.Length;
byte[] b = new byte[fileLen];
e.Result.Read(b, 0, b.Length);
dataFile.Write(b, 0, b.Length);
dataFile.Flush();
object lenghtOfFile = dataFile.Length;
dataFile.Close();
order.Visibility = Visibility.Visible;
ProgressBar1.Visibility = Visibility.Collapsed;
MessageBox.Show("Arquivo salvo!");
}
private void client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
ProgressBar1.Visibility = Visibility.Visible;
this.ProgressBar1.Value = e.ProgressPercentage;
}
