Do you know any software or online web application or a tool in Visual Studio that can do this conversion?

And please someone help me, I can’t convert this complex (to Linq Like This : From x in UserRoleid Select x … Where …)

        var Result = userRoleIds.Select(s => (s.UserId, actionFullNames.Select(actionFullName 
          => (actionFullName, permissions.Any(A => s.RoleIds.Contains(A.RoleId) && 
          A.ActionFullName.Equals(actionFullName, StringComparison.OrdinalIgnoreCase))))
         .ToArray())).ToArray();
