◆ NetworkAccess

enum System.Net.NetworkAccess
strong

Specifies network access permissions.

Enumerator
Accept 

Indicates that the application is allowed to accept connections from the Internet on a local resource.

Connect 

Indicates that the application is allowed to connect to specific Internet resources. Notice that, in the case of remote host resource, no check is performed to see that Connect permissions exist. This is because the port of a connecting remote host is unknown and not suitable permissions can be built in advance. It is the application responsibility to check the permissions of the remote host trying to connect to a listening socket.

Tcp 

TCP transport.

ConnectionOriented 

The transport is connection oriented, such as TCP. Specifying this value has the same effect as specifying F:System.Net.TransportType.Tcp.

All 

All transport types.

Definition at line 4 of file TransportType.cs.

◆ WebExceptionStatus

enum System.Net.WebExceptionStatus
strong

Defines status codes for the T:System.Net.WebException class.

PipelineFailure 

The request was a piplined request and the connection was closed before the response was received.

A message was received that exceeded the specified limit when sending a request or receiving a response from the server.

CacheEntryNotFound 

The specified cache entry was not found.

RequestProhibitedByCachePolicy 

The request was not permitted by the cache policy. In general, this occurs when a request is not cacheable and the effective policy prohibits sending the request to the server. You might receive this status if a request method implies the presence of a request body, a request method requires direct interaction with the server, or a request contains a conditional header.

RequestProhibitedByProxy
