Is it possible to send a collection of ID's as a ADO.NET SQL parameter?

Question

Eg. can I write something like this code:

public void InactiveCustomers(IEnumerable customerIDs)
{
    //...
    myAdoCommand.CommandText =

You can use xml parameter type:

CREATE PROCEDURE SelectByIdList(@productIds xml) AS

DECLARE @Products TABLE (ID int) 

INSERT INTO @Products (ID) SELECT ParamValues.ID.value('.','VARCHAR(20)')
FROM @productIds.nodes('/Products/id') as ParamValues(ID) 

SELECT * FROM 
    Products
INNER JOIN 
    @Products p
ON    Products.ProductID = p.ID
