求图片上传
求asp.net图片上传代码，在数据库中存的是图片名，不是地址，存在电脑硬盘中.有合适的发在404956675@qq.com或写在楼下。。 --------------------编程问答-------------------- 图片上传？网上一搜一堆。。。。保存图片名的时候。。你自己截取就是了。。。。 --------------------编程问答-------------------- 百度，google一下就一大堆了。 珍惜你的分数啊。
上传控件下面就直接有一个属性获得图片名的。 还有个属性是获得全路径。
--------------------编程问答-------------------- protected void btnUpload_Click(object sender, EventArgs e)
{
if (fileUpload.HasFile)
{
string savePath = Server.MapPath("~/upload/");
if(!System.IO.Directory.Exists(savePath))
{
System.IO.Directory.CreateDirectory(savePath);
}
savePath = savePath + "\\" + fileUpload.FileName;
fileUpload.SaveAs(savePath);//保存文件
string filename=fileUpload.FileName;
}
}

顶，这个就可以了
但是图片不能太大，好像超过2M就上传不上去了吧。 --------------------编程问答-------------------- if (FileUpload1.PostedFile.FileName == "")
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "dd", "alert('请选择要传的图片！');", true);
return;
}
string filePath = FileUpload1.PostedFile.FileName;//获取图片文件的路径
string imgname = filePath.Substring(filePath.LastIndexOf('/') + 1);
//如果不需要重命名的话就直接取imgname这个值就是文件名
string imgtype = filePath.Substring(filePath.LastIndexOf('.') + 1).ToLower();
string savePath = "";//图片要保存的路径
string filename = "";//文件名
if (imgtype == "jpg" || imgtype == "jpeg" || imgtype == "gif" || imgtype == "bmp")
{
filename = DropDownListSort.SelectedValue + "_" + DropDownListBrand.SelectedValue + "_" + DateTime.Now.ToFileTime().ToString() + "." + imgtype;//给图片重命名
savePath = Server.MapPath("~/images/Goods/" + filename);//要保存的物理文件路径
FileUpload1.PostedFile.SaveAs(savePath);//保存图片
