public bool IsBusy {get;} | |
Remarks
Concurrent asynchronous calls are not supported using the ArcGISWebClient class. This means that it is not possible to have multiple ArcGISWebClient operations to return results from ArcGIS Server. Use the ArcGISWebClient.IsBusy Property to determine if an existing operation is running before issuing the ArcGISWebClient.DownloadStringAsync or ArcGISWebClient.OpenReadAsync Methods to avoid the Visual Studio runtime error: NotSupportedException was unhandled by user code. "Request does not support concurrent I/O operations."
Property Value
true to indicate a Web request is in progress; otherwise, false.Requirements
