C# Winform怎么设计串口,客户端和相机控件界面显示

---

首先我们必须把这个类创建好

INIAPI

using System;
using System.Text;
using System.Runtime.InteropServices;

namespace Ini
{
    public class IniAPI
    {
        #region INI文件操作

        /*
         * 针对INI文件的API操作方法，其中的节点（Section)、键（KEY）都不区分大小写
         * 如果指定的INI文件不存在，会自动创建该文件。
         * 
         * CharSet定义的时候使用了什么类型，在使用相关方法时必须要使用相应的类型
         *      例如 GetPrivateProfileSectionNames声明为CharSet.Auto,那么就应该使用 Marshal.PtrToStringAuto来读取相关内容
         *      如果使用的是CharSet.Ansi，就应该使用Marshal.PtrToStringAnsi来读取内容
         *      
         */
