如何用C#查询sql Server 2005中是否存在“表名”表，如果不存在则使用此“表名”创建表

C# code

                    SqlConnection myCon2 = new SqlConnection();                    myCon2.ConnectionString = "Persist Security Info=False;User id=sa;pwd=111111;database=message;server=(local)";                    myCon2.Open();                    Console.WriteLine("请输入员工编号：");                    string user_id = Console.ReadLine();                    SqlDataAdapter adp = new SqlDataAdapter();                    DataTable dt = myCon2.GetSchema();                    try                    {                        SqlCommand cmd = new SqlCommand("select * from user_id" , myCon2);                        cmd.ExecuteNonQuery();                    }                    catch (SqlException ex) {                        switch (ex.Number) {                             case 1146:                                Console.WriteLine("无此表，创建表");                                string mySelectQuery="CREATE TABLE user_id(usermessage VARCHAR(MAX))";                                SqlCommand cmd = new SqlCommand(mySelectQuery, myCon2);                                cmd.ExecuteNonQuery();                                Console.Read();                                break;                            default:                                break;                        }                    }

我想通过输入的员工编号user_id来判定数据库中是否存在表名为user_id的表，如果没有则以输入的编号为表名创建表。可是上面的代码不能实现这个功能，请各位大侠指点迷津。谢谢

[解决办法]
select count(*) from sysobjects where id = object_id("数据库名.Owner.表名")



[解决办法]
或者做成存储过程：

if not exists(select * from sysobjects where id=object_Id('dbo.user_id') )
CREATE TABLE user_id(usermessage VARCHAR(MAX))
