Excel download and open error from portal

Once we download excel file from portal and try to open file the below error will be shown.

The code used for the download is as follows.
HttpContext.Current.Response.TransmitFile(filepath);
System.IO.File.Delete(filepath);
HttpContext.Current.Response.End();

Here the issue comes because the file will be deleted immediately once the file transmitted. During this time the original file will be locked by other process.

So changing the code as below will resolves the issue.

HttpContext.Current.Response.TransmitFile(filepath);
HttpContext.Current.Response.Flush();
System.IO.File.Delete(filepath);
HttpContext.Current.Response.End();

Error in Batch Job: Stack trace: Invalid attempt to call WinAPI.fileSize running in CIL on the client.

Batch Job end with error in Log as follows..

To solve this modify the method by using System.IO namespace classes as below..

fileInfo   = new System.IO.FileInfo(attachFileName);
fileSize = fileInfo.get_Length();

This will solve the issue and Batch will work without errors
