WebClientProtocol.Timeout Property
.NET Framework 4
Indicates the time an XML Web service client waits for the reply to a synchronous XML Web service request to arrive (in milliseconds).
Assembly: System.Web.Services (in System.Web.Services.dll)
Setting the Timeout property to Timeout.Infinite indicates that the request does not time out. Even though an XML Web service client can set the Timeout property to not time out, the Web server can still cause the request to time out on the server side.
