Select alerts are resolved in last 2 days using Expressions in SCOM connector subscription Criteria

Hi,

I need to select alerts are resolved in last 2 days using Expressions in SCOM connector subscriptions.

AlertChangedSubscriptionConfiguration config = new AlertChangedSubscriptionConfiguration(AlertSubscriptionConfigurationType.Any);
 config.PollingIntervalMinutes = 1;
 config.Criteria = @"

<Expression>??????</Expression>";

So here Provide Expression sample code to retrieve all alerts are resolved in last 2 days.

Thanks,
