How to Delete a file using asp.net?

Question

i write the code in asp.net using c# to delete the file in my computer, but it is not deleting please help me thank u. this is my code, i write in button click event

        string path = "E:\\sasi\\delt.doc";
        FileInfo myfileinf = new FileInfo(path);
        myfileinf.Delete();

1) You aren't trying to delete a file in the client side using ASP.NET code are you? 2) Checking myfileInf.Exists would help. 3) You should show us the Delete exception because I don't think it's not throwing one — Andre Pena

public void DeleteFileFromFolder(string StrFilename)
{

    string strPhysicalFolder = Server.MapPath("..\\");

    string strFileFullPath = strPhysicalFolder + StrFilename;

    if (IO.File.Exists(strFileFullPath)) {
        IO.File.Delete(strFileFullPath);
    }

}

I converted it to VB, and it worked like a charm. Thank you, nearly 13 years later.

In order to delete a file you must ensure that the account has sufficient permissions. In general ASP.NET applications run under limited permission account such as Network Service. For example if your application runs under IIS 6 you could go to the Administration Console and set a custom account in the application pool properties:

You need to ensure that the account is member of the IIS_WPG group.

Make sure the ASP user has permissions to this folder. By default this user is not given access to much of the harddrive..
