maxrequestlength引起的
.默认情况下上传时,图片不能超过4MB.
我知道这可以从web.config文件更改.
当我尝试通过显示另一个页面来尝试解决此错误时,会弹出一个不同的错误.调试时,程序立即进入application_error.
执行Server.GetLastError()时生成异常：
[System.Web.HttpUnhandledException] {“Exception of type
‘System.Web.HttpUnhandledException’ was

如果我在application_error方法中尝试任何代码,例如重定向,仍然是错误页面：
错误101(net :: ERR_CONNECTION_RESET)：连接已重置.
被展示.
问题

解决方法
在web.config中的系统Web下
添加此行..
<system.web> <httpRuntime executionTimeout="999" maxRequestLength="2097151"/>
然后你需要检查文件大小
if (AsyncFileUpload1.HasFile)
{
string FileName = Path.GetFileName(AsyncFileUpload1.PostedFile.FileName);
string Extension = Path.GetExtension(AsyncFileUpload1.PostedFile.FileName);
string FolderPath = ConfigurationManager.AppSettings["FolderPath"];
string FilePath = Server.MapPath("~/xl/" + FileName);
double filesize = (double)AsyncFileUpload1.FileBytes.Length;
if (filesize < 106496)
{
//do something
}
else
{
Response.Write("File size must be less than 2MB.");
}
