.net从远程下载文件的问题

我的项目在本地上传文件和下载文件都好用；之后把项目放在服务器上后；上传没有问题，下载的时候，我是指定放在 E：/files/文件下；  却下载载到服务器的E：/files/上了；怎么下载到本地自己的电脑上？
数据库 A表字段 filePath 是存放文件的路径的;

string filePath ="E:\test\ShopWeb\Admin\Upload\file\1.jpg"; //从数据库读取文件的路径
WebClient wlent = new WebClient();
  if (!Directory.Exists("E:/files/"))
  {
     DirectoryInfo dif = Directory.CreateDirectory("E:/files/");
  }
  string d = filePath.Substring(filePath.LastIndexOf("\\"));
  wlent.DownloadFile(filePath, "E:/files/" + d);

请高手指点！！！。。谢谢 --------------------编程问答--------------------         /// <summary>

        } --------------------编程问答-------------------- 两种方法：
1，使用write或流下载
2、使用超链接下载 --------------------编程问答-------------------- 使用相对路径
using (System.Net.WebClient client = new System.Net.WebClient())
{
  client.DownloadFile("", "");
}
WebClient wc = new WebClient();
  Byte[] bytes = wc.DownloadData("");
  using (FileStream fs = new FileStream(fileName, FileMode.OpenOrCreate))
  {
  fs.Write(bytes, 0, bytes.Length);
  }
