T-SQL的IN：
Select ProductID, ProductName, CategoryID From dbo.Products Where CategoryID in (1, 2)
T-SQL的NOT IN：
Select ProductID, ProductName, CategoryID From dbo.Products Where CategoryID not in (1, 2)
Or
Select ProductID, ProductName, CategoryID From dbo.Products Where not CategoryID in (1, 2)
LINQ的IN：
var queryResult = from p in db.Products where (new int?[] {1,2}).Contains(p.CategoryID) select p;

SELECT [t0].[ProductID], [t0].[ProductName], [t0].[SupplierID], [t0].[CategoryID], [t0].[QuantityPerUnit], [t0].[UnitPrice], [t0].[UnitsInStock], [t0].[UnitsOnOrder], [t0].[ReorderLevel], [t0].[Discontinued] FROM [dbo].[Products]AS [t0] WHERE [t0].[CategoryID] IN (@p0, @p1)
LINQ的NOT IN：
var queryResult = from p in db.Products where ! (new int?[] {1,2}).Contains(p.CategoryID) select p;
LINQ的NOT IN解析成SQL：
SELECT [t0].[ProductID], [t0].[ProductName], [t0].[SupplierID], [t0].[CategoryID], [t0].[QuantityPerUnit], [t0].[UnitPrice], [t0].[UnitsInStock], [t0].[UnitsOnOrder], [t0].[ReorderLevel], [t0].[Discontinued] FROM [dbo].[Products]AS [t0] WHERE NOT [t0].[CategoryID] IN (@p0, @p1)
