How do I use my enumeration in a LinqToSQL query?

Question

I have a field in my database table that use to store an enumeration value, e.g.:

create table MyTable (
  ...
  Status tinyint not null,
  ...
)


        

Answer 1

Don't have a compiler handy, but I think if you cast your enum to an int, it will work. So try:

var q = MyDataContext.GetTable().Where(t => t.MyStatus == (int)TStatus.Active);

As links die - and at least for me this one did die - here is the important part:

[When adding the column to the entity] by default, the Type will come up as an "int (System.Int32)", but you can change it to the fully-qualified type of the enum (in my case, ConsoleApplication1.CustomerType). BUT, in order to locate it fully, you have to add the global identifier, as follows: global::ConsoleApplication1.CustomerType , so type that as is (but the equivalent for your namespace) into the textbox
