    Toggle

    Hello,

    I need to set the property IsActive = false for all records but one
    which has FileID = id

    database.Files. Select(p =p.FileID != id)

    I am selecting the records ... I just don't know how to change the
    IsActive of all this records to false.

    If possible using lambda.

    Thanks,
    Miguel

      I also tried:
      database.Files. Where(p =p.FileID != id).Select(p =p.IsActive =
      false);

      But I get an error:
      An expression tree may not contain an assignment operator

          Not directly, no. For some reason, there's no "ForEach()" method in the
          Enumerable class.

          But, you can certainly just write a foreach() loop and do it explicitly.
