Networking

Tip

This article covers Uno-specific information for Windows.Networking namespace. For a full description of the feature and instructions on using it, consult the UWP documentation: https://learn.microsoft.com/en-us/uwp/api/windows.networking

• The Windows.Networking namespace provides classes for accessing and managing network connections from your app.

Checking for internet connectivity

You can use the following snippet to check for internet connectivity level in a cross-platform manner:

var profile = NetworkInformation.GetInternetConnectionProfile();
if (profile == null)
{
    // No connection
}
else
{
    var level = profile.GetNetworkConnectivityLevel();
    // level is a value of NetworkConnectivityLevel enum
}

Android can recognize all values of NetworkConnectivityLevel. iOS, macOS and WASM return either None or InternetAccess.

Note: On Android, the android.permission.ACCESS_NETWORK_STATE permission is required. It can be added to the application manifest or with the following attribute in the Android platform head:

[assembly: UsesPermission(\"android.permission.ACCESS_NETWORK_STATE\")]

iOS/macOS reachability host name

On iOS and macOS, it is necessary to make an actual "ping" request, to verify that internet connection is accessible. The default domain that is checked is www.example.com, but you can change this to be any other domain by setting the WinRTFeatureConfiguration.NetworkInformation.ReachabilityHostname property.
