WebClient::UploadStringTaskAsync Method (String^, String^)
Uploads the specified string to the specified resource as an asynchronous operation using a task object.
Assembly: System (in System.dll)
public: [ComVisibleAttribute(false)] [HostProtectionAttribute(SecurityAction::LinkDemand, ExternalThreading = true)] Task<String^>^ UploadStringTaskAsync( String^ address, String^ data )
The URI of the resource to receive the string. For HTTP resources, this URI must identify a resource that can accept a request sent with the POST method, such as a script or ASP page.
The string to be uploaded.
This operation will not block. The returned Task<TResult> object will complete after the string has been uploaded to the resource. The string is sent asynchronously using thread resources that are automatically allocated from the thread pool.
Asynchronous operations that have not completed can be canceled using the CancelAsync method.
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.
