如何将文本信息连同图片一起上传。。。。

Question

<INPUT id="upimage" type="file" runat="server">
图片上传到指定目录]
 同时将文本信息提交到数据库中

Answer 1

文本信息你从哪里输入呢??
是不是应该多加一个textbox控件呢?
再判断upimage对象的内容类型合法且textbox不为空时,先传upimage到指定目录,指保存textbox的值到数据库.

Answer 2

如果是需要文本信息和图片放在一起,就使用FreeTextBox控件,不过也要注意图片的路径.

3、上传图片
CODE:  [Copy to clipboard]
--------------------------------------------------------------------------------System.Drawing.Image image,newimage;                                     //定义image类的对象
                protected string imagePath;                                              //图片路径
                protected string imageType;                                              //图片类型
                protected string imageName;
                protected System.Web.UI.WebControls.RadioButtonList choice;                                              //图片名称
                System.Drawing.Image.GetThumbnailImageAbort callb =null;                 //提供一个回调方法，用于确定Image对象在执行生成缩略图操作时何时提前取消执行，如果此方法确定GetThumbnailImage方法应提前停止执行，则返回true,否则返回false
CODE:  [Copy to clipboard]
--------------------------------------------------------------------------------private void btn_upload_Click(object sender, System.EventArgs e)
                {
