ASP文件上传无声故障 [英] ASP FileUpload Silent Fail
问题描述
我在使用使用文件上传大文件的问题。如果我上传一个小文件（10KB〜），它工作正常。上传大文件（60MB〜）不会抛出异常，它只是重新加载页面。之前有人问：＆LT;的httpRuntime的maxRequestLength =2097151executionTimeout =3600waitChangeNotification =1maxWaitChangeNotification =3600requestValidationMode =2.0/＆GT;
I'm having a problem using using FileUpload for large files. If I upload a small file (~10kB), it works fine. Uploading a large file (~60MB) does not throw an exception, it just reloads the page. Before anyone asks: <httpRuntime maxRequestLength="2097151" executionTimeout="3600" waitChangeNotification="1" maxWaitChangeNotification="3600" requestValidationMode="2.0" />
页：
<%@ AutoEventWireup="true" CodeFile="~/LargeFileUploadControl.aspx.cs" Inherits="LargeFileUploadControl" %>
<html>
<body>
<form runat="server">
<asp:Label ID="theOnlyLabel" runat="server" Text="Uploaded files will go to a place"/><br />
<asp:FileUpload ID="theOnlyUpload" runat="server" /><br />
<asp:Button ID="theOnlyButton" onClick="StartUpload" Text="Upload" runat="server" />
</form>
</body>
</html>
背后code：
public partial class LargeFileUploadControl:Page
{
public string _uploadDir;
/// <summary>
/// Content loaded event handler
/// </summary>
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
_uploadDir = "D:\\web\\tikt.imaginuity.com\\TIKT\\media\\TIKT\\Global Large Uploads\\";
theOnlyLabel.Text = "Uploaded files will go to " + _uploadDir;
}
protected void StartUpload(object sender, EventArgs e)
{
if (theOnlyUpload.HasFile)
{
theOnlyLabel.Text = "Uploading...";
theOnlyUpload.SaveAs(_uploadDir + theOnlyUpload.FileName);
theOnlyLabel.Text = "File saved to " + _uploadDir + theOnlyUpload.FileName;
}
else
{
theOnlyLabel.Text = "No file to upload";
}
return;
}
}
编辑：我已经尝试下面的接受的答案，我这样想着。展望我再次发现，有的两个的＆LT; system.webServer方式＆gt; 在我的web.config这两个需要改变的部分。
EDIT : I had already tried the accepted answer below, or so I thought. Looking again I discovered that there were two <system.webServer> sections in my web.config that both needed the change.
推荐答案
这将解决您的问题，如果您使用的是IIS7。我在上传文件的大小超过400MB，
This will fix your issue, if you are using iis7. I tested on upload file size more than 400MB,
在添加元素下web.config文件中进行配置。
Add the following configuration in your web.config file under element.
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="524288000"/>
</requestFiltering>
</security>
