HttpStatusCode | The HTTP status code of the navigation if it involved an HTTP request. For instance, this will usually be 200 if the request was successful, 404 if a page was not found, etc. See https://developer.mozilla.org/docs/Web/HTTP/Status for a list of common status codes. |
IsSuccess | true when the navigation is successful; false for a navigation that ended up in an error page (failures due to no network, DNS lookup failure, HTTP server responds with 4xx). |

Properties
HttpStatusCode
readonly int HttpStatusCode
The HTTP status code of the navigation if it involved an HTTP request. For instance, this will usually be 200 if the request was successful, 404 if a page was not found, etc. See https://developer.mozilla.org/docs/Web/HTTP/Status for a list of common status codes.
The HttpStatusCode
property will be 0 in the following cases:
- The navigation did not involve an HTTP request. For instance, if it was a navigation to a
file://
URL, or if it was a same-document navigation. - The navigation failed before a response was received. For instance, if the hostname was not found, or if there was a network error.
In those cases, you can get more information from the CoreWebView2NavigationCompletedEventArgs.IsSuccess and CoreWebView2NavigationCompletedEventArgs.WebErrorStatus properties.
If the navigation receives a successful HTTP response, but the navigated page calls window.stop()
before it finishes loading, then HttpStatusCode may contain a success code like 200, but CoreWebView2NavigationCompletedEventArgs.IsSuccess will be false
and CoreWebView2NavigationCompletedEventArgs.WebErrorStatus will be CoreWebView2WebErrorStatus.ConnectionAborted.
Since WebView2 handles HTTP continuations and redirects automatically, it is unlikely for HttpStatusCode to ever be in the 1xx or 3xx ranges.
IsSuccess
readonly bool IsSuccess
true
when the navigation is successful; false
for a navigation that ended up in an error page (failures due to no network, DNS lookup failure, HTTP server responds with 4xx).
This may also be false
for additional scenarios such as window.stop()
run on navigated page.
NavigationId
readonly uint64_t NavigationId
Gets the ID of the navigation.
WebErrorStatus
readonly CoreWebView2WebErrorStatus WebErrorStatus
Gets the error code if the navigation failed.
