Fields

Name Value Description
Success 0

No error was encountered.

NameResolutionFailure 1

The name resolver service could not resolve the host name.

ConnectFailure 2

The remote service point could not be contacted at the transport level.

ReceiveFailure 3

A complete response was not received from the remote server.

SendFailure 4

A complete request could not be sent to the remote server.

PipelineFailure 5

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

RequestCanceled 6

The request was canceled, the Abort() method was called, or an unclassifiable error occurred. This is the default value for Status.

ProtocolError 7

The response received from the server was complete but indicated a protocol-level error. For example, an HTTP protocol error such as 401 Access Denied would use this status.

ConnectionClosed 8

The connection was prematurely closed.

TrustFailure 9

A server certificate could not be validated.

SecureChannelFailure 10

An error occurred while establishing a connection using SSL.

ServerProtocolViolation 11

The server response was not a valid HTTP response.

KeepAliveFailure 12

The connection for a request that specifies the Keep-alive header was closed unexpectedly.

Pending 13

An internal asynchronous request is pending.

Timeout 14

No response was received during the time-out period for a request.

ProxyNameResolutionFailure 15

The name resolver service could not resolve the proxy host name.

UnknownError 16

An exception of unknown type has occurred.

MessageLengthLimitExceeded 17

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

CacheEntryNotFound 18

The specified cache entry was not found.

RequestProhibitedByCachePolicy 19

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 20

This request was not permitted by the proxy.

Remarks

The WebExceptionStatus enumeration defines the status codes assigned to the Status property.
