临时文件怎么删？

[oy656]

Response.Clear()
Response.AppendHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(scFileName, System.Text.Encoding.UTF8))
Response.AddHeader("content_length", thefile.Length.ToString)
Response.WriteFile(thePath)
Response.End()
我用上面的程序执行的下载功能，但是response.end执行完以后，再以下的程序就不执行了，所以我没办法把下载前临时生成的文件删除，这样的话生成的文件势必越来越多，而且这些文件都没用了，谁有经验或是好办法可以解决。谢了先

string strFile = "e:\\test.doc";
FileStream fs = new FileStream(strFile, FileMode.Open);
byte[] bytes = new byte[(int)fs.Length];
fs.Read(bytes, 0, bytes.Length);
fs.Close();
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(File.Name)) //中文名
Response.BinaryWrite(bytes);
Response.End();

换一种思路，每次下载前首先去删除(以前的)临时文件

同意楼上：
void Page_Load(Object Src,EventArgs E) {
if (!IsPostBack)
fileEntries = Directory.GetFiles(Server.MapPath("temp"));
foreach(string fileName in fileEntries){
File.Delete(fileName);
