这个看不懂额。用input type=file上传怎么上传？

[wongeo]

<form action="exec/Upload.ashx" enctype="multipart/form-data" method="post">
<input name="file" type="file" />
<input type="submit" value="提交" />
</form>

aspx页面写这些。

public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
HttpFileCollection imgs = context.Request.Files;
if (imgs.Count>0)
{
for (int i = 0; i < imgs.Count; i++)
{
if (imgs[i].ContentLength!=0)
{
string oldName=imgs[i].FileName.ToString();
string imgName = Guid.NewGuid().ToString();
string imgType = oldName.ToString().Substring(oldName.LastIndexOf("."));
string imgPath = "~/upload/" + imgName + imgType;
imgs[i].SaveAs(context.Server.MapPath(imgPath));
}
}
}
}

一般处理程序写这些

exec/Upload.ashx
upload
Default.aspx
文件目录

这个里面是源代码

[我就是大神]

操作的内容还得ashx写啊。input file只是获得个路径而已。ashx根据路径上传到某个文件夹啊。

form表单加个最后那个属性。
<form action="03-PhotoAdd.ashx" method="post" enctype="multipart/form-data">

前面还得加个隐藏标签，起个name=viewstate
input标签。
<input type="text" name="txtDes" value=" " />
<input type="submit" value="上传" />

ashx写。
string viewstate = context.Request.Form["viewstate"];
if (!string.IsNullOrEmpty(viewstate))
{
string path = context.Request.Form["txtDes"];

HttpPostedFile file = null;
if (context.Request.Files.Count > 0)
{
file = context.Request.Files[0];
下面这是起个随机名字而已
Random r = new Random();
string filename = DateTime.Now.ToString("yyyyMMddhhmmss") + r.Next(10000, 100000) + System.IO.Path.GetExtension(file.FileName);

string filepath = context.Request.MapPath("imgs/" + filename ); imgs只是网站里的文件夹，我是用来存上传的图片的
file.SaveAs(filepath);
}
else
{
//MessageBox.Show(context, "请上传文件");
//context.Response.Write(html);
}

可能还会有点错，大概就是这样
