C#实现控件数组

下面的代码实现修改显示器分辨率和刷新频率的功能：

using System;

using System.Drawing;

using System.Collections;

using System.ComponentModel;

using System.Windows.Forms;

using System.Data;

using System.Runtime.InteropServices;

namespace ScreenResolution

{

public class Form1 : System.Windows.Forms.Form

{

public enum DMDO

{

DEFAULT = 0,

D90 = 1,

D180 = 2,

D270 = 3

}

[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Auto)]

struct DEVMODE

{

public const int DM_DISPLAYFREQUENCY = 0x400000;

public const int DM_PELSWIDTH = 0x80000;

public const int DM_PELSHEIGHT = 0x100000;

private const int CCHDEVICENAME = 32;

private const int CCHFORMNAME = 32;

[MarshalAs(UnmanagedType.ByValTStr, SizeConst=CCHDEVICENAME)]
