我正在尝试使用 ASP.NET 制作一个简单的上传文件控件,但它不起作用:
这是我的代码(.aspx):
<form id="form1" runat="server">
<div>
upload a file now.
<asp:FileUpload ID="fileupload1" runat="server" />
<asp:Button ID="button1" Text="Upload" runat="server" Width="73px"
onclick="button1_Click" />
<asp:Label ID="Label1" runat="server" Font-Bold="True" ForeColor="#000099">
</asp:Label>
</div>
</form>
这是我背后的代码(.cs):
if(fileupload1.HasFile)
{
try
{
if(fileupload1.PostedFile.ContentType == "image/jpeg")
{
if(fileupload1.PostedFile.ContentLength < 51200000)
{
string filename = Path.GetFileName(fileupload1.FileName);
fileupload1.SaveAs(Server.MapPath("~/img/") + filename);
Label1.Text ="File uploaded successfully!";
}
else
Label1.Text ="File maximum size is 500 Kb";
}
else
Label1.Text ="Only JPEG files are accepted!";
}
catch(Exception exc)
{
Label1.Text = "The file could not be uploaded. The following error occured: "
+ exc.Message;
}
}
该文件未在服务器中显示..有什么想法吗?
当我断点时,它们都有效,应用程序获取代码,一切正常,但不会将其保存到文件夹中。
