The following example shows how to perform an asynchronous FindFolder call.

// Create the request.
FindFolderType request = new FindFolderType();
request.FolderShape = new FolderResponseShapeType();
request.FolderShape.BaseShape = DefaultShapeNamesType.AllProperties;
request.Traversal = FolderQueryTraversalType.Deep;
request.ParentFolderIds = new BaseFolderIdType[1];
DistinguishedFolderIdType root = new DistinguishedFolderIdType();
root.Id = DistinguishedFolderIdNameType.root;
request.ParentFolderIds[0] = root;
// Send the asynchronous request.
esb.FindFolderAsync(request);
// Wait for the response.
while (!handled)
{
Thread.Sleep(1000);
Console.Write("Waiting\r\n");
}
}
static private bool handled = false;
static void HandleFindFolderCompleted(object sender, FindFolderCompletedEventArgs e)
{
if ((!e.Cancelled) && (e.Error == null))
