问题描述
好了,所以我想选择多个图像,并将它们保存在asp.net的数据库。
我不希望使用任何插件或任何类型的脚本
这是设计师页:
< ASP:文件上传的AllowMultiple =真正的ID =fileuploadimages=服务器/>
< ASP:按钮=服务器ID =btnUpload的CssClass =btnStyle文本=上传图片
的OnClick =btnUpload_Click/>
我迄今按钮上传活动做到了这一点。它所做的是,它可以让我选择多个文件,就像如果我选择3张图片,它在我的数据库三次保存第一个文件和文件夹图片中曾将其保存,而不是保存所有三种。
保护无效btnUpload_Click(对象发件人,EventArgs五)
{
如果(fileuploadimages.HasFile ==假)
{
ScriptManager.RegisterStartupScript(页,Page.GetType(),重点,<脚本>警报('没有文件上传。')< / SCRIPT>中,FALSE);
}
,否则
{
的foreach(在fileuploadimages.PostedFiles var文件)
{
字符串文件名= Path.GetFileName(fileuploadimages.PostedFile.FileName) ;
fileuploadimages.SaveAs(使用Server.Mappath(../图片/+文件名));
的SqlCommand CMD =新的SqlCommand(插入到
EventPageView(EVENT_NAME,Event_Text,IMAGE_PATH)
值(@事件名称,@ EventText,@的ImagePath),conn);在
cmd.Parameters.AddWithValue(@的ImagePath,文件名);
cmd.Parameters.AddWithValue(@事件名称,txtEventName.Text);
cmd.Parameters.AddWithValue(@ EventText,txtEnterDesc.Text);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
BindDataList();
}
}
}
更改这两行的行:
字符串文件名= Path.GetFileName(fileuploadimages.PostedFile.FileName);
fileuploadimages.SaveAs(使用Server.Mappath(../图片/+文件名));
到
字符串文件名= Path.GetFileName(file.FileName);
file.SaveAs(使用Server.Mappath(../图片/+文件名));
我希望这会有所帮助。因为你必须使用对象文件
Okay, so I'm trying to select multiple images and save them in a database in asp.net.I don't want to use any plugins or any kind of scripts.
This is the designer page:
<asp:FileUpload AllowMultiple="true" ID="fileuploadimages" runat="server" />
<asp:Button runat="server" ID="btnUpload" CssClass="btnStyle" Text="Upload Image"
OnClick="btnUpload_Click" />
I have done this so far on the button upload event. What it does is that it allows me to select more than one file, like if I select 3 images, it saves the first file thrice in my database and saves it once in the folder "Pictures" instead of saving all three.
protected void btnUpload_Click(object sender, EventArgs e)
{
if (fileuploadimages.HasFile == false)
{
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", "<script>alert('No File Uploaded.')</script>", false);
}
else
{
foreach (var file in fileuploadimages.PostedFiles)
{
string filename =Path.GetFileName(fileuploadimages.PostedFile.FileName);
fileuploadimages.SaveAs(Server.MapPath("../Pictures/" + filename));
SqlCommand cmd = new SqlCommand("Insert into
EventPageView(Event_name,Event_Text,Image_Path)
values(@EventName,@EventText,@ImagePath)", conn);
cmd.Parameters.AddWithValue("@ImagePath", filename);
cmd.Parameters.AddWithValue("@EventName", txtEventName.Text);
cmd.Parameters.AddWithValue("@EventText", txtEnterDesc.Text);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
BindDataList();
}
}
}
Change those two lines line:
string filename = Path.GetFileName(fileuploadimages.PostedFile.FileName);
fileuploadimages.SaveAs(Server.MapPath("../Pictures/" + filename));
to
string filename = Path.GetFileName(file.FileName);
file.SaveAs(Server.MapPath("../Pictures/" + filename));
I hope it will help. Because you must use the object file
