public class FileUploadHandler : IHttpHandler
{
    private const string UPLOAD_RESOURCES_FOLDER_NAME = "UploadResources";
    public void ProcessRequest(HttpContext context)
    {
        foreach (string fname in context.Request.Files.AllKeys)
        {
            string guidFileName = Guid.NewGuid().ToString();
            HttpPostedFile file = context.Request.Files[fname];
            file.SaveAs(context.Server.MapPath("~/" + UPLOAD_RESOURCES_FOLDER_NAME) +
                        "//" + guidFileName + file.FileName);
            Uri addressUri = context.Request.Url;
            string httpFilePath = string.Format("{0}://{1}/{2}/{3}",
                                                addressUri.Scheme,
                                                addressUri.Authority,
                                                UPLOAD_RESOURCES_FOLDER_NAME,
                                                guidFileName + file.FileName);
            context.Response.Write(httpFilePath);
        }
    }
    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

这段代码主要是获取客户端请求的Files，然后调用SaveAs方法保存到服务器端得UploadResources文件夹下，

接着返回一个http的路径给客户端。

上传的代码如下：

2：Ftp上传

首先需要新建Ftp站点：

可以使用工具创建，也可以使用iis来创建Ftp站点，在这里我使用iis来承载。

创建好Ftp站点后，假设

站点地址是：ftp://192.168.0.11/

用户名是：WQ,

密码是：123456.

那么上传的代码如下：

public static void Main()
{
    WebClient webClient = new WebClient();
    webClient.Credentials = new NetworkCredential("WQ", "123456");
    string ftpUrl = "ftp://192.168.0.11";
    string fileName = "c:\\test.txt";
    string uploadFilePath = string.Format("{0}{1}{2}", 
                                            ftpUrl,
                                            DateTime.Now.ToString("yyyyMMddHHmmss"),
                                            Path.GetFileName(fileName));
    webClient.UploadFile(uploadFilePath, fileName);
}
