Parameters

address

The URI of the resource to receive the file. This URI must identify a resource that can accept a request sent with the method method.

method

The HTTP method used to send the string to the resource. If null, the default is POST for http and STOR for ftp.

data

The string to be uploaded.

Return Value

A String containing the response sent by the server.

Exception typeCondition

WebException

The URI formed by combining BaseAddress and address is invalid.

-or-

There was no response from the server hosting the resource.

-or-

method cannot be used to send content.

Before uploading the string, this method converts it to a Byte array using the encoding specified in the Encoding property. This method blocks while the string is transmitted. To send a string and continue executing while waiting for the server's response, use one of the UploadStringAsync 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.
