下载文件

Question

            XmlDocument doc = new XmlDocument();
            doc.Load(@"D:\Project\C#Test\WindowsApplication1\WindowsApplication1\XMLFile1.xml");            XmlNodeList nodeList = doc.SelectNodes("//LocalFileList//FileName");
            List <string> values = new List <string>();
            foreach (XmlElement element in nodeList)
            {                if (!values.Contains(element.InnerText))
                {
                    Debug.WriteLine(string.Format("FileName:{0}", element.InnerText));
                    values.Add(element.InnerText);
                }
            }显示过后，如何下载那些文件喃？现在路径保存在一个变量里。
比如：a
该如何写喃？
谢谢啊

Answer 1

给你个函数,调用这个下载 
把文件名(带路径)和你下载显示的文件标题作为参数传入就行  private void DownLoad(string filepath, string filetitle) 
{
    System.IO.FileInfo fi=new System.IO.FileInfo(filepath);        
    System.Web.HttpContext.Current.Response.Clear();
    System.Web.HttpContext.Current.Response.ClearHeaders();
    System.Web.HttpContext.Current.Response.Buffer = false;
    System.Web.HttpContext.Current.Response.ContentType = "application/octet-stream";
    System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(filetitle, System.Text.Encoding.UTF8));
    System.Web.HttpContext.Current.Response.AppendHeader("Content-Length", fi.Length.ToString());
    System.Web.HttpContext.Current.Response.WriteFile(fi.FullName);
    System.Web.HttpContext.Current.Response.Flush();
    System.Web.HttpContext.Current.Response.End();
}

问题解决了            XmlDocument mydoc = new XmlDocument();
            mydoc.Load("AutoUpdater.xml");
            string a = mydoc.GetElementsByTagName("URLAddres")[0].InnerText;                int b = chFileName.ListView.Items.Count;
                while (b > 0)
                {
                    b = b-1;
                    string DFILE = chFileName.ListView.Items[b].Text;
                    string filePath = a + DFILE;
                    WebClient Client = new WebClient();
                    Client.DownloadFile(filePath, @"C:\TEMP\downfile\" + DFILE);
                    
                }
