9.用ExecuteSqlCommand执行存储过程

比如你有一个存储过程

IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id =
   OBJECT_ID(N'[dbo].[CreateAuthor]') AND type in (N'P', N'PC'))

BEGIN
    EXEC dbo.sp_executesql @statement = N'
    CREATE PROCEDURE [dbo].[CreateAuthor]
        @FirstName Varchar(50),
        @LastName Varchar(50),
        @Address Varchar(100)
    AS
    INSERT INTO dbo.Authors(
        [FirstName],
        [LastName],
        [Address]
    )
    VALUES (@FirstName, @LastName, @Address)
    '

using (var context = new BookStore())
{
    int affectedRows = context.Database.ExecuteSqlCommand("CreateAuthor @p0, @p1, @p2",
        parameters: new[]
        {
            "Mark",
            "Cuban",
            "23 Tsawassen Blvd."
        });
}
