这时在作测试时扒下来的代码有的丢掉了，只有个修补方案。大家凑合着看吧。东西很简单。
string str = filename.Substring(filename.LastIndexOf(".") + 1, 3);
if (str == "png" || str == "gif" || str == "jpg" || str == "jpeg" || str == "PNG" || str == "GIF" || str == "JPG" || str == "JPEG")
{
string sfd = savePath;
string sf = filename.Substring(0, filename.LastIndexOf(".")) + "_" + DateTime.Now.ToString("yyMMddhhmmss") + "." + str;
savePath += filename + sf;
this.hidurl.Value = "SecFile/" + sf;//保存URL这段上传代码，验证文件名是从最后“点”算起的，也就是提交后缀为gif就行，在往下看在生成新文件名时也是用的lastindexof()函数进行的截取，之后保存的，由于服务器是IIS6.0直接POST文件名为1.asp;1.jpg就ok。修复代码：[code="csharp"]string sf =DateTime.Now.ToString("yyMMddhhmmss") + "." + str;[/code]-----<font face="宋体 "><code id="code1">fileurl = context.Request["folder"];</code></font>
从请求头里取文件夹地址。iis6直接截断或分号
