我正在尝试从我的网络目录(在IIS上)下载图像文件,因此我尝试使用Web客户端通过循环来下载文件。我有2个应用程序,1个是我部署的Web应用程序,另一个是WPF应用程序,我尝试从Web应用程序下载文件。这是我的代码:
public StartWindow()
{
InitializeComponent();
string fileUploadDirectory = ConfigurationManager.AppSettings.Get("path");
// string fullpath = System.IO.Path.Combine(fileUploadDirectory, daoWordPuzzle.GetfileURL().Substring(2)); // removes ( ~/ ) .
string fullpath = "http://localhost/iStellarMobile_deploy/Designs/";
DirectoryInfo d = new DirectoryInfo(fullpath);
FileInfo[] Files = d.GetFiles("*.png");
foreach (FileInfo file in Files)
{
string root = file.DirectoryName;
DownloadFile(root);
}
}
protected void DownloadFile(string urlAddress)
{
client = new WebClient();
string currentpath = System.IO.Directory.GetCurrentDirectory() + @"\ImagesTest"; // Save under ImagesTest folder.
client.DownloadFile(urlAddress, currentpath);
}
图片位于Designs的文件夹中..这就是我想下载的内容...... 然后在我的App.config中:
<appSettings>
<add key="path" value="http://localhost/iStellarMobile_deploy" />
但是当我运行WPF应用程序时,它在这一行显示错误:
DirectoryInfo d = new DirectoryInfo(fullpath);
错误:不支持URI格式。
之前我正在使用(这适用于下载文本文件,但不适用于多个文本文件):
protected void DownloadData(string strFileUrlToDownload)
{
WebClient client = new WebClient();
byte[] myDataBuffer = client.DownloadData(strFileUrlToDownload);
MemoryStream storeStream = new MemoryStream();
storeStream.SetLength(myDataBuffer.Length);
storeStream.Write(myDataBuffer, 0 , (int)storeStream.Length);
storeStream.Flush();
string currentpath = System.IO.Directory.GetCurrentDirectory() + @"\Folder"; //folder to contain files.
using (FileStream file = new FileStream(currentpath, FileMode.Create, System.IO.FileAccess.ReadWrite))
{
byte[] bytes = new byte[storeStream.Length];
storeStream.Read(bytes, 0, (int)storeStream.Length);
file.Write(myDataBuffer, 0, (int)storeStream.Length);
storeStream.Close();
}
//The below Getstring method to get data in raw format and manipulate it as per requirement
string download = Encoding.ASCII.GetString(myDataBuffer);
}
我部署的网站位于C:/ inetpub / wwwroot。我做错了什么?我试图通过在目录中循环它们来下载多个文件。
