调用System.Windows.Forms DLL

首先在Unity新建Plugins文件夹添加System.Windows.Forms.dll

然后代码中添加引用

using System;

using UnityEngine;

using System.Collections;

using System.Collections.Generic;

using System.Windows.Forms;

using System.IO;

    public UIButton BtnNew;

    public UIButton BtnOpen;

    public UIButton BtnSave;

    public UIButton BtnSaveAs;

    public UIButton BtnClose;

    #endregion

    #region private

    SaveFileDialog saveLog;

    StreamReader sr;

    StreamWriter sw;

    string strSendTxt;

    UIPaneAuto uiPanelAuto;//一个显示文本和输入文本的文本框所在的类

    #endregion
