Assembly: System.Net (in System.Net.dll)


Public Property BaseAddress As String
public string BaseAddress { get; set; }

Property Value

Type: System..::.String
The base URI for requests made by a WebClient. If no base address has been specified, the BaseAddress property is initialized to the application origin (the absolute URI of the Windows Phone XAP).


Exception Condition

BaseAddress is set to an invalid URI. The inner exception may contain information that will help you locate the error.


The BaseAddress property contains a base URI that is combined with a relative address. When you call a method that uploads or downloads data, the WebClient object combines this base URI with the relative address you specify in the method call. If you specify an absolute URI, WebClient does not use the BaseAddress property value. To remove a previously set value, set BaseAddress to nullNothingnullptra null reference (Nothing in Visual Basic) or an empty string ("").
