文件类型验证
protected void Button1_Click(object sender, EventArgs e)

{

    if (FileUpload1.HasFile)

    {

        fileExt = System.IO.Path.GetExtension(FileUpload1.FileName);

        if (fileExt == ".jpg" || fileExt == ".gif")

        {

            try

            {

                FileUpload1.SaveAs(Server.MapPath("upload") + "\\" + FileUpload1.FileName);

                Label1.Text = "客户端路径：" + FileUpload1.PostedFile.FileName + "
" +

                              "文件名：" + System.IO.Path.GetFileName(FileUpload1.FileName) + "
" +

                              "文件扩展名：" + System.IO.Path.GetExtension(FileUpload1.FileName) + "
" +

                              "文件大小：" + FileUpload1.PostedFile.ContentLength + " KB
" +

                              "文件MIME类型：" + FileUpload1.PostedFile.ContentType + "
" +

                              "保存路径：" + Server.MapPath("upload") + "\\" + FileUpload1.FileName;

            }

            catch (Exception ex)

            {

                Label1.Text = "发生错误：" + ex.Message.ToString();

            }

        }

        else

        {

            Label1.Text = "只允许上传jpg、gif文件！";

        }

    }

    else

    {

        Label1.Text = "没有选择要上传的文件！";

    }

}

上传
protected void Button1_Click(object sender, EventArgs e)

{

    if (FileUpload1.HasFile)

    {

        try

        {

            FileUpload1.SaveAs(Server.MapPath("upload") + "\\" + FileUpload1.FileName);

            Label1.Text = "客户端路径：" + FileUpload1.PostedFile.FileName + "
" +

                          "文件名：" + System.IO.Path.GetFileName(FileUpload1.FileName) + "
" +

                          "文件扩展名：" + System.IO.Path.GetExtension(FileUpload1.FileName) + "
" +

                          "文件大小：" + FileUpload1.PostedFile.ContentLength + " KB
" +

                          "文件MIME类型：" + FileUpload1.PostedFile.ContentType + "
" +

                          "保存路径：" + Server.MapPath("upload") + "\\" + FileUpload1.FileName;

        }

        catch (Exception ex)

        {

            Label1.Text = "发生错误：" + ex.Message.ToString();

        }

    }

    else

    {

        Label1.Text = "没有选择要上传的文件！";

    }

}

补充上传限制





maxRequestLength表示可上传文件的最大值，executionTimeout表示ASP.NET关闭前允许发生的上载秒数。
