WebClient::UploadData Method (Uri, String, array<Byte>)
Uploads a data buffer to the specified resource, using the specified method.
Assembly: System (in System.dll)
public: array<unsigned char>^ UploadData( Uri^ address, String^ method, array<unsigned char>^ data )
- Type: System::Uri
The URI of the resource to receive the data.
- Type: System::String
The HTTP method used to send the data to the resource. If null, the default is POST for http and STOR for ftp.
- Type: array<System::Byte>
The data buffer to send to the resource.
The UploadData method sends a data buffer to a resource using the HTTP method specified in the method parameter, and returns any response from the server. This method blocks while uploading the data. To continue executing while waiting for the server's response, use one of the UploadDataAsync methods.
The UploadData method sends the content of data to the server without encoding it.
If the method parameter specifies a verb that is not understood by the server, the underlying protocol classes determine what occurs. Typically, a WebException is thrown with the Status property set to indicate the error.
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.
