Downloads the resource as a String from the URI specified as an asynchronous operation using a task object.
Assembly: System (in System.dll)
[ComVisibleAttribute(false)] [HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)] public Task<string> DownloadStringTaskAsync( Uri address )
The URI of the resource to download.
This operation will not block. The returned Task<TResult> object will complete after the data resource has been downloaded. The resource is downloaded asynchronously using thread resources that are automatically allocated from the thread pool.
After downloading the resource, this method uses the encoding specified in the Encoding property to convert the resource to a String. This method does not block the calling thread while downloading the resource.
You can use the CancelAsync method to cancel asynchronous operations that have not completed.
If the BaseAddress property is not an empty string ("") and address does not contain an absolute URI, address must be a relative URI that is combined with BaseAddress to form the absolute URI of the requested data. If the QueryString property is not an empty string, it is appended to address.
This method uses the RETR command to download an FTP resource. For an HTTP resource, the GET method is used.
