IEnumerable - Where

[shapper]

Hello,

I created a function the returns an IEnumerable

public static IEnumerable GetMembershipCr eateStatus(Cult ureInfo
culture) {
switch (culture.TwoLet terISOLanguageN ame.ToLower()) {
case "en":
return new[] {
new { Name = MembershipCreat eStatus.Duplica teEmail,
Description = "..." },
new { Name =
MembershipCreat eStatus.Duplica teProviderUserK ey, Description =
"..." },
};
}
return null;
}

I am trying to use and filter this list as follows:

string error =
Asset.GetMember shipCreateStatu s(Thread.Curren tThread.Current Culture).Where( s
=s.Name ==
MembershipCreat eStatus.Duplica teEmail).Single OrDefault().Des cription;

I get an error:

'System.Collect ions.IEnumerabl e' does not contain a definition for
'Where' and no extension method 'Where' accepting a first argument of
type 'System.Collect ions.IEnumerabl e' could be found (are you missing
a using directive or an assembly reference?)

If I use it inside my method Where is recognized:

case "en":
return new[] {
new { Name = MembershipCreat eStatus.Duplica teEmail,
Description = "..." },
new { Name =
MembershipCreat eStatus.Duplica teProviderUserK ey, Description =
"..." },
}.Where(s =s.Name = Input);

What am I doing wrong?

Thanks,

Miguel

You're trying to use it on the plain nongeneric IEnumerable. Where is
only defined for the generic IEnumerable<Tty pe.
