Open any file from asp.net

How can I open any file, specified by a path, in ASP.NET programatically?

I tried the snippet below but it reads the contents of the fil开发者_StackOverflowe instead of opening the file:

string fileName = @"C:\deneme.txt";        
StreamReader sr = File.OpenText(fileName);        
while (sr.Peek() != -1)        
{            
    Response.Write(sr.ReadLine() + "<br>");        
}        
sr.Close();

I also tried the File.Open method.

You can Response.Redirect to file if you're just opeining it

or if file is being downloaded you can use the folling code;

    public void DownloadFile(string fileName)
    {
        Response.Clear();
        Response.ContentType = @"application\octet-stream";
        System.IO.FileInfo file = new System.IO.FileInfo(Server.MapPath(FileName));
        Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
        Response.AddHeader("Content-Length", file.Length.ToString());
        Response.ContentType = "application/octet-stream";
        Response.WriteFile(file.FullName);
        Response.Flush();
    }

If you want the file to be opened on the client side,Create an HTTP Handler and set the appropriate mime type on your response before streaming it out from your handler.

for more information I ask question near to your one before.
