网上有很多方案，起初用时，因为对asp.net不太了解，觉得FTP实现不错，可是后来发现，如果机器在域控下，就会有问题。
一年过去了，asp.net也熟悉了，知道ajax没事应该用ashx，验证码也用ashx，当然这里要说的WinForm上传也应该是ashx了吧，哈哈，先提供简单思路：
接收文件的asp.net是：Uploader.ashx，相关代码：
- <%@ WebHandler Language="C#" Class="Uploader" %>
- using System;
- using System.IO;
- using System.Web;
-
- public class Uploader : IHttpHandler
- {
- public void ProcessRequest(HttpContext hc)
- {
- foreach (string fileKey in hc.Request.Files)
- {
- HttpPostedFile file = hc.Request.Files[fileKey];
- file.SaveAs(Path.Combine(hc.Server.MapPath("."), file.FileName));
- }
- }
-
- public bool IsReusable
- {
- get { return true; }
- }
- }
<%@ WebHandler Language="C#" Class="Uploader" %>
using System;
using System.IO;
using System.Web;
public class Uploader : IHttpHandler
{
public void ProcessRequest(HttpContext hc)
{
foreach (string fileKey in hc.Request.Files)
{
HttpPostedFile file = hc.Request.Files[fileKey];
file.SaveAs(Path.Combine(hc.Server.MapPath("."), file.FileName));
}
}
public bool IsReusable
{
get { return true; }
}
}
发送图片或文件的WinForm.cs 相关代码：
- System.Net.WebClient myWebClient = new System.Net.WebClient();
- myWebClient.UploadFile("http://www.yongfa365.com/Uploader.ashx", "POST", "C:\\WINDOWS\\system32\\cmd.exe");
System.Net.WebClient myWebClient = new System.Net.WebClient();
myWebClient.UploadFile("http://www.yongfa365.com/Uploader.ashx", "POST", "C:\\WINDOWS\\system32\\cmd.exe");
OK,完了，这样操作后，再也不用管是不是在域控内了，只要能上网，就能上传。够方便吧。
如果你要批量上传，还有上传后保存在哪个目录等操作可以参考柳永法(yongfa365)'Blog写的：

{

{
File.Delete(FilePath);
}
else
{
continue;
}
}
file.SaveAs(FilePath);
}
}
public bool IsReusable
{
get { return true; }
}
}
发送图片或文件的WinForm.cs 相关代码：
- string url = @"http://www.yongfa365.com/Uploader.ashx?Overwrite=true&PATH=Logs\" + DateTime.Now.ToString("yyyy-MM-dd");
- foreach (string file in Directory.GetFiles(item))
- {
- System.Net.WebClient myWebClient = new System.Net.WebClient();
- myWebClient.UploadFile(url, "POST", file);
- }
string url = @"http://www.yongfa365.com/Uploader.ashx?Overwrite=true&PATH=Logs\" + DateTime.Now.ToString("yyyy-MM-dd");
foreach (string file in Directory.GetFiles(item))
{
System.Net.WebClient myWebClient = new System.Net.WebClient();
myWebClient.UploadFile(url, "POST", file);
}
