How do you pass into a method a generic after you've reflected? [Answered]

// source is of type System.Collections.IEnumerable
var type = source.GetType();
var interfaces = type.GetInterfaces();
for (int i = 0; i < interfaces.Length; i++)
{
    var @interface = interfaces[i];
    if (@interface is null)
        continue;
    // null check satisifed 
    if(@interface.GenericTypeArguments.Length == 1 && @interface.GetGenericTypeDefinition() == typeof(IReadOnlyList<>))
    {
        // found it. It is in fact an IReadOnlyList<T> where T : struct 
        // but now what? Can I get a strongly typed reference to an IReadOnlyList<T> where T : struct ? 
    }
}

// source is of type System.Collections.IEnumerable
var type = source.GetType();
var interfaces = type.GetInterfaces();
for (int i = 0; i < interfaces.Length; i++)
{
    var @interface = interfaces[i];
    if (@interface is null)
        continue;
    // null check satisifed

    {
        // found it. It is in fact an IReadOnlyList<T> where T : struct 
        // but now what? Can I get a strongly typed reference to an IReadOnlyList<T> where T : struct ? 
    }
}
