WebClient.UploadData Method (Uri, Byte)
Uploads a data buffer to a resource identified by a URI.
Assembly: System (in System.dll)
- Type: System.Uri
The URI of the resource to receive the data.
- Type: System.Byte
The data buffer to send to the resource.
The UploadData method sends a data buffer to a resource.
This method uses the STOR command to upload an FTP resource. For an HTTP resource, the POST method is used. If the underlying request 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.
The UploadData method sends the content of data to the server without encoding it. This method blocks while uploading the data. To continue executing while waiting for the server's response, use one of the UploadDataAsync methods.
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.
