在saveas的时候写好路径和你想起的文件名就可以了

嘿嘿，刚准备给你发短信呢
我这样写的，但是不行
protected void Upload_Click(object sender, EventArgs e)
{
name = FileUpload.FileName;
string type = FileUpload.PostedFile.ContentType;
string size = FileUpload.PostedFile.ContentLength.ToString();
string newname =Convert.ToString( System.DateTime.Now);
string path = Server.MapPath("~/Images/Product/" + newname);

if (type == "image/pjpeg" || type == "image/gif" || type == "image/bmp")
{
FileUpload.SaveAs(path);
Image.ImageUrl = "~/Images/Product/" + newname;
message.Text = "上传名称:" + newname + "大小:" + size + "路径:" + path;
Labelname.Text = newname;
}
else
{
Response.Write("<script>alert('" + "上传类型仅限于gif,jpg,mbp格式图片" + "')</script>");
}

}


哪错了啊？

以前做的,可以用


//Int64 intImageSize;
//string strImageType;
//Stream ImageStream;

//intImageSize = PersonImage.PostedFile.ContentLength;

//strImageType = PersonImage.PostedFile.ContentType;

//ImageStream = PersonImage.PostedFile.InputStream;

//Byte[] ImageContent = new Byte[intImageSize];

//int intStatus = ImageStream.Read(ImageContent, 0, PersonImage.PostedFile.ContentLength);
if (myFile.PostedFile.ContentLength != 0)
{
if (myFile.PostedFile != null)
{
string nam = myFile.PostedFile.FileName;
//Response.Write(nam);
//取得文件名(抱括路径)里最后一个"."的索引

int i = nam.LastIndexOf(".");
//取得文件扩展名

newext = nam.Substring(i);
//这里我自动根据日期和文件大小不同为文件命名,确保文件名不重复
DateTime now = DateTime.Now;
newname = now.DayOfYear.ToString() + myFile.PostedFile.ContentLength.ToString();

//保存文件到你所要的目录,这里是IIS根目录下的uploadfiles目录
//注意: 我这里用Server.MapPath()取当前文件的绝对目录.在asp.net里"\"必须用"\\"代替
myFile.PostedFile.SaveAs(Request.PhysicalApplicationPath + "images\\ftb\\updata\\" + newname + newext);
//myFile.PostedFile.SaveAs("D:\\kmsite\\images\\ftb\\updata\\" + newname + newext);
//myFile.PostedFile.SaveAs(Server.MapPath(".\\UpLoadFiles\\" + newname + newext));
}

DBOp dbop = new DBOp(Request.PhysicalApplicationPath);
int a = dbop.OpenDataBase();
if (a == 1)
{
//int selectr = Convert.ToInt32(this.RadioButtonList1.SelectedValue);
//if (selectr == 1)
//{
