Check in an array of object

Question

I have an array of an object say ClientsDTO[]. There is a property namely Tin in the object. I want to check if a value is present in the array. I have one way of checking this i.e. using the LINQ query and getting the list of objects which satisfies the condition. If the returned list is null then the value is not present in the array. If the list exists then value is present in the array. The following is a sample code.

I want to know is there a better way than this i.e. something more elegant and with better performance. I am using VS 2008, 3.5 framework.

ClientsDTO[] client = new ClientsDTO[10];

var lstclient = client.Where(c => c.TIN == anyNumber).FirstOrDefault();
if (lstclient == null)
{
    //value present in array
}
else
{
   //value not present
}

Thanks in advance!

@abatishchev: The question clearly says "I am using VS 2008, 3.5 framework". It was originally tagged with C# 3.0, which is not the same thing as .NET 3.0. I don't understand how either your edit or your comment applies. — Cody Gray

You could use the overload of Any that takes a predicate:

bool valueIsPresent = client.Any(c => c.TIN == anyNumber);
