请教高手为什么我的files.count得到的都是0呢
HttpFileCollection files=HttpContext.Current.Request.Files;int i,err;
// ID=0;
err=0;
string fileName,fileExtension,SaleExtension,message;
// url="";
message="";
SaleExtension="|.jpg|,|.gif|,|.png|";
//try
{
//检验上传的所有图片
if(files.Count>0)
{
for(i=0;i<files.Count;i++)
{
HttpPostedFile file=files[i];
fileName=System.IO.Path.GetFileName(file.FileName);
fileExtension=System.IO.Path.GetExtension(file.FileName).ToLower();
if(file.ContentLength>(500*1024))
{
err=1;
message+="<b>"+file.FileName+"</b>图片太大,请选择小一点的图片上传!<br>";
}
if(file.ContentLength<1)
{
err=8;
message+="<b>"+file.FileName+"</b>图片错误,请确定选择的是正确的文件路径!<br>";
}
if(SaleExtension.IndexOf("|"+fileExtension+"|")<0)
{
err=2;
message+="<b>"+file.FileName+"</b>文件类型不正确,只能上传(.gif,.jpg,.png)类型的图片文件!<br>";
}
}
}
else
{
err=7;//未上传图片
message+="未上传图片<br>";
}
}
//catch
{
//err=100;
