Ejemplos

En el ejemplo de código siguiente se recopila información del usuario (nombre, edad y dirección) y se envía los valores al servidor mediante UploadValues. Cualquier respuesta del servidor se muestra en la consola.

Comentarios

El método UploadValues envía un NameValueCollection a un servidor. Este método bloquea al cargar los datos. Para continuar ejecutándose mientras espera la respuesta del servidor, use uno de los métodos UploadValuesAsync.

Si el servidor no entiende la solicitud subyacente, las clases de protocolo subyacente determinan lo que ocurre. Normalmente, se produce un WebException con la propiedad Status establecida para indicar el error.

Si el encabezado Content-type es null, el método UploadValues lo establece en "application/x-www-form-urlencoded".

Si la propiedad BaseAddress no es una cadena vacía ("") y address no contiene un URI absoluto, address debe ser un URI relativo combinado con BaseAddress para formar el URI absoluto de los datos solicitados. Si la propiedad QueryString no es una cadena vacía, se anexa a address.

Este método usa el comando STOR para cargar un recurso FTP. Para un recurso HTTP, se usa el método POST.

El método UploadValues envía un NameValueCollection a un recurso mediante el método especificado en el parámetro method y devuelve cualquier respuesta del servidor. Este método bloquea al cargar los datos. Para continuar ejecutándose mientras espera la respuesta del servidor, use uno de los métodos UploadValuesAsync.

Si el encabezado Content-type es null, el método UploadValues lo establece en application/x-www-form-urlencoded.

Si el parámetro method especifica un verbo que el servidor no entiende, las clases de protocolo subyacente determinan lo que ocurre. Normalmente, se produce un WebException con la propiedad Status establecida para indicar el error.

Si la propiedad BaseAddress no es una cadena vacía ("") y address no contiene un URI absoluto, address debe ser un URI relativo combinado con BaseAddress para formar el URI absoluto de los datos solicitados. Si la propiedad QueryString no es una cadena vacía, se anexa a address.
