Define many properties

Hello,

I have the following:
Articles.Select(a => a.IsPublished = true);

But when I try to define two properties:
Articles.Select(a => a.IsPublished = true, a.UpdateAt = DateTime.Now);

I get an error on the second 'a':
The name 'a' does not exist in the current context

Am I doing something wrong or I can't do this with Linq?

Thanks,
Miguel
 
I think that, in that context, 'a' only exists within the first
condition (a => a.IsPublished = true). By putting a comma, maybe you
are creating a different scope. Try joining all your conditions using
operators.

Hope it helps,

Luis

What you want to do is to AND your conditions. The Select method does not
accept multiple conditions as separate arguments. Also, be carefull with the
comparison operator: one "equals" (=) means "assign", two equals (==) means
"is equal?".

Articles.Select(a => a.IsPublished && a.UpdateAt == DateTime.Now);
 
Articles.Select(a => a.IsPublished && a.UpdateAt == DateTime.Now);
Click to expand...

Also note that a.UpdateAt == DateTime.Now will probably never yield true.
