Using more than one condition in linq's where method

Question

I have a line of code using where:

codebase.Methods.Where(x => x.Body.Scopes.Count > 5);

How can I insert more than one condition? So

Answer 1

You can roll your separate conditions into a single predicate if you like:

codebase.Methods.Where(x => (x.Body.Scopes.Count > 5) && (x.Foo == "test"));

Or you can use a separate Where call for each condition:

codebase.Methods.Where(x => x.Body.Scopes.Count > 5)
                .Where(x => x.Foo == "test");

Answer 2

no you can't define 2 delegates in the same where but you can build after each other or put both on same condition like this

 var result = codebase.Methods.Where(x => x.Body.Scopes.Count > 5 && x.Body.Scopes.name == "" );

or 

 var result = codebase.Methods.Where(x => x.Body.Scopes.Count > 5 )
        .where( y=> y.Body.Scopes.name == '' );

or 

 var result = codebase.Methods.Where(x => x.Body.Scopes.Count > 5  )
.Union( codebase.Methods.Where(y => y.Body.Scopes.name == ''  ) );

Answer 3

What would "y" represent?

You can just use a standard && condition. No need for a "y":

codebase.Methods.Where(x => x.Body.Scopes.Count > 5 && x.Body.SomethingElse < 14);

Answer 4

I don't get it. What can you not do?

codebase.Methods.Where(x => x.Head.IsHairy && x.Body != null && x.Body.Scopes.Count > 5); 

Answer 5

like this..

codebase.Methods.Where(x => x.Body.Scopes.Count > 5 && x.Body.Scopes.Count < 10);

Answer 6

codebase.Methods.Where(x => x.Body.Scopes.Count > 5).Where(x => x.Body.Scopes.TypeName == "Scopes").Where(x => x.Body.Scopes.Level == LEVEL_HIGH);
