IEnumerable doesn't have Count
- by Alexander
I have the following method:
public bool IsValid
{
get { return (GetRuleViolations().Count() == 0); }
}
public IEnumerable<RuleViolation> GetRuleViolations(){
//code here
}
Why is it that when I do .Count above it is underlined in red?
I got the following error:
Error 1 'System.Collections.Generic.IEnumerable'
does not contain a definition for
'Count' and no extension method
'Count' accepting a first argument of
type
'System.Collections.Generic.IEnumerable'

using directive or an assembly
reference?) c:\users\a\documents\visual
