ienumerable doesnt have a count method


ienumerable doesnt have a count method  using -'c#,asp.net,enumerable'

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'
  could be found (are you missing a
  using directive or an assembly
  reference?)   c:\users\a\documents\visual
