WebClient.BaseAddress Property

Gets or sets the base URI for requests made by a WebClient.

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

member BaseAddress : string with get, set

Property Value

Type: System.String
A String containing the base URI for requests made by a WebClient or Empty if no base address has been specified.

ExceptionCondition
ArgumentException

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 this property to a null reference (Nothing in Visual Basic) or an empty string ("").

The following code example downloads data from an Internet server and displays it on the console. It assumes that the server's address (such as http://www.contoso.com) is in hostUri and that the path to the resource (such as /default.htm) is in uriSuffix.
