DestinationFileName Property

Summary
Gets the download operation destination file name.

Syntax
C#
C++/CLI
Python
public string DestinationFileName { get; } 
public: 
property String^ DestinationFileName { 
   String^ get(); 
} 
DestinationFileName # get  (SharePointClientDownloadCompletedEventArgs) 

Property Value

The download operation destination file name.

Remarks

This is the same value as the destinationFileName parameter passed to DownloadFileAsync if this method was called to initiate the download. If GetDownloadStreamAsync was called to initiate the download, then the value of this property is null (Nothing in VB).

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.SharePoint.Client;

   // "Documents" or "Documents\Sub Documents" 
   string folderName = SHAREPOINT_FOLDER_NAME;

   // MyDocument.tif

   spClient.Credentials = new NetworkCredential(USER_NAME, PASSWORD, DOMAIN);

   // so use a wait handle to not exit this method till the opreation completes
