“The process cannot access the file ‘d:\MarketingSystem\ExcelImport\Sample.xls’ because it is being used by another process.”

getting error in this line

  RevenueDumpFileUpload.PostedFile.SaveAs(Server.MapPath(strFilePathOnServer) + RevenueDumpFileUpload.FileName);

This is my full code…..

 protected void btnImport_Click(object sender, EventArgs e)
{
    if (RevenueDumpFileUpload.HasFile)
    {

        string strFilePathOnServer = ConfigurationManager.AppSettings["RevenueDumpFileLocation"];
        String sConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath(strFilePathOnServer) + RevenueDumpFileUpload.FileName + ";Extended Properties=Excel 8.0;";
        string strPostedFileName = RevenueDumpFileUpload.PostedFile.FileName;
        if (strPostedFileName != string.Empty && RevenueDumpFileUpload.PostedFile.ContentLength != 0)
        {
            //Delete Old file before uploading new file. 
            if (System.IO.File.Exists(strFilePathOnServer))
            {
                System.IO.File.Delete(strFilePathOnServer);

            }
            //Save-Upload File to server. 
            RevenueDumpFileUpload.PostedFile.SaveAs(Server.MapPath(strFilePathOnServer) + RevenueDumpFileUpload.FileName);
            RevenueDumpFileUpload.FileContent.Dispose();
        }
        OleDbConnection Exlcon = new OleDbConnection(sConnectionString);
        try
        {
            Exlcon.Open();
        }
        catch
        {
            return;
        }
        finally
        {
            RevenueDumpFileUpload.PostedFile.InputStream.Flush();
            RevenueDumpFileUpload.PostedFile.InputStream.Close();
        }

        OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM [Sheet1$]", Exlcon);
        OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
        objAdapter1.SelectCommand = objCmdSelect;
        objAdapter1.Fill(objDataset1, "XLData");
        methodtosave();

    }

}

In my web config file:

    <appSettings>
<add key="RevenueDumpFileLocation" value="~/ExcelImport/"/>

How to resolve this?

Help me..

Thanks in advance

You forget to pass the File Name and File Extension when you are trying to delete the file.

if (System.IO.File.Exists(Server.MapPath(strFilePathOnServer) + strPostedFileName+ 
    System.IO.Path.GetExtension(RevenueDumpFileUpload.FileName)))
{
   System.IO.File.Delete(Server.MapPath(strFilePathOnServer) + strPostedFileName +
   System.IO.Path.GetExtension(RevenueDumpFileUpload.FileName) );
}
