Namespace:  System.Web.Mvc
Assembly:  System.Web.Mvc (in System.Web.Mvc.dll)

	Stream^ fileStream, 
	String^ contentType, 
	String^ fileDownloadName
)

Parameters

fileStream
Type: System.IO::Stream
The stream to send to the response.
contentType
Type: System::String
The content type (MIME type)
fileDownloadName
Type: System::String
The file name to display in the file-download dialog box that is displayed in the browser.

Return Value

Type: System.Web.Mvc::FileStreamResult
The file-stream result object.

The fileDownloadName parameter is used to generate the content-disposition header. The content-disposition header must use US ASCII encoding. Therefore, the fileDownloadName parameter must use US ASCII encoding. The result object that is prepared by this method is written to the response by the MVC framework when the object is executed. The MediaTypeNames class can be used to get the MIME type for a particular file extension.

The following example shows how to open a file-download dialog box and set the file name to the name of the server file. The id parameter contains the server file name.
