Unity3D使用System.Windows.Forms.dll

using UnityEngine;
using System.Collections;
using System.Windows.Forms;

public class Test : MonoBehaviour
{

    // Use this for initialization
    void Start()
    {

    }

    // Update is called once per frame
    void Update()

    }

    void OnGUI()
    {
        if (GUI.Button(new Rect(0, 0, 100, 20), "Button"))
        {
            MessageBoxYesCancel("yes");

    }

    public static DialogResult MessageBoxYesCancel(string Information)//通用弹出式信息显示对话框方法(进行互操作)返回***感汉号
    {
        string caption = "【系统提示】";
        MessageBoxButtons buttons = MessageBoxButtons.YesNoCancel;

        return MessageBox.Show(Information, caption, buttons, MessageBoxIcon.Question);
