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;
        }
    }

在C#中,您不能拥有索引属性.也就是说,如何将以下代码从VB.net转换为C#？

Private _PatchSpectrum(49) As Double

Public ReadOnly  Property GetPatchSpectrum() As Double()
    Get
        Return _PatchSpectrum
    End Get
End Property

Public WriteOnly Default Property PatchSpectrum(idx As Integer) As Double
    Set(ByVal value as Double)
        _PatchSpectrum(idx) = value
    End Set
End Property
