C# fileName display with spaces trouble

Question

Suppose I have a report Name as :

string reportName = "Facebook Network Performance Summary Report (By Region, By Content)";

and I would like to display that file name as excel

the below is my code to export the file

Response.AddHeader("Content-Disposition", "attachment; filename=" reportName + ".xls");
Response.AddHeader("Content-Length", l.ToString());
Response.ContentType = "application/vnd.ms-excel";
Response.BinaryWrite(f);

Unluckily, thewhen reading the first space of my reportName, it only shows Facebook and no else.

Is there any wexisting API for ASP.NET or other methods to handle the spaces of fileNAme ?

Answer 1

Try wrapping the filename in double quotes.

 string filename = reportName + ".xls";
 Response.AddHeader("Content-Disposition", "attachment; filename=\"" + filename + "\"");

Answer 2

You need to wrap the filename in quotes:

Response.AddHeader("Content-Disposition", "attachment; filename=\"" + reportName + "\".xls");
