连接池

Question

我有以下代码,如果我最后使用conn == null,我仍然使用连接池？我知道关闭连接是一个好习惯但是如何处理整个连接对象？

    public void ExecuteNonQuery(SqlCommand Cmd)
    {
        //========== Connection ==========//
        SqlConnection Conn = new SqlConnection(strConStr);

        try
        {
            //========== Open Connection ==========//
            Conn.Open();

            //========== Execute Command ==========//
            Cmd.Connection = Conn;
            Cmd.CommandTimeout = 180;
            Cmd.ExecuteNonQuery();
        }
        catch (Exception Exc)
        {
            throw Exc;
        }
        finally
        {
            //======== Closing Connection ========//
            if (Conn.State == ConnectionState.Open)
            { Conn.Close(); }

            //======== Disposing object ========//
            Conn = null;
        }
    }

首先,考虑使用using,其次,让框架处理.在管理供应商将根据连接字符串做池.

public void ExecuteNonQuery(SqlCommand Cmd) 
{ 
    //========== Connection ==========// 
    using(SqlConnection Conn = new SqlConnection(strConStr))
    { 
        //========== Open Connection ==========// 
        Conn.Open(); 

        //========== Execute Command ==========// 
        Cmd.Connection = Conn; 
        Cmd.CommandTimeout = 180; 
        Cmd.ExecuteNonQuery(); 
    } 
}
