Json.TimeInterval

Extends System.Text.Json with a custom new TimeInterval type. Be aware, it is implemented for deserialization or read only!

{
    "TheDevice": {
        "Timeout": "3s",
        "PollingInterval": "500ms",
        "RefreshTokenEvery": "1h 15m"
    }
}

Format

Use string quotes "" to decorate values:

"KeyName": "1500ms"

• Only unsigned integer values for time units.
• Possible delimeters: - _:/' (space included).
• "3m 1h 2m" is equivalent to "1h 5m". Identical time units are sum up: 3m + 2m = 5m.
• System TimeSpan is allowable, so "00:01:02:000" is equivalent to "1h 2m".

Examples

• "1h34m26s134ms"
• "1h 12m127s"
• "1d/12h 15m 7s"
• "3d/12h_15m:12s---347ms"

How to use

public class MyClass_ToDeserializeJson
{
    public Device TheDevice {get; set;}

    public class Device 
    {
        public TimeInterval Timeout {get; set;}
            = TimeSpan.FromSeconds( 3 );

        public TimeInterval PollingInterval {get; set;}
            = TimeSpan.FromMilliseconds( 500 );

        public TimeInterval RefreshTokenEvery {get; set;}
            = TimeSpan.FromHours( 1 )
            + TimeSpan.FromMinutes( 15 ) );
    }
}

...

public async Task Main()
{
    TimeSpan pollingInterval =
        // Use streams not strings! This is just a short example.
        JsonSerializer.Deserialize<MyClass_ToDeserializeJson>(
            File.ReadAllText( "./devsettings.json" ) )
        .TheDevice
        .PollingInterval;

    while (!Console.KeyAvailable) {
        Debug.Write(".")
        await Task.Delay( pollingInterval );
    }
}
