1.找到System.Windows.Forms.dll，并放在project中的Plugins文件夹下。 “D:\Unity3D\Editor\Data\Mono\lib\mono\2.0\System.Windows.Forms.dll”

2.打开Player Settings 把.NET 2.0 Subset 改为.NET 2.0;

3.选择的图片路径中不能存在中文

using UnityEngine;using System.Collections;using System;using System.Windows.Forms;using System.IO;public class ReadPic : MonoBehaviour {public Texture2D img = null;void OnGUI(){if (GUI.Button(new Rect(0, 0, 100, 20), "选择文件")){OpenFileDialog od = new OpenFileDialog();od.Title = "请选择头像图片";od.Multiselect = false;od.Filter = "图片文件(*.jpg,*.png,*.bmp)|*.jpg;*.png;*.bmp";if (od.ShowDialog() == DialogResult.OK){Debug.Log(od.FileName);StartCoroutine(GetTexture("file://"+od.FileName));}}if (img != null){GUI.DrawTexture(new Rect(0, 20, img.width, img.height), img);}}IEnumerator GetTexture(string url){WWW www = new WWW(url);yield return www;if (www.isDone && www.error == null){img = www.texture;Debug.Log(img.width + "  " + img.height);byte[] data = img.EncodeToPNG();//File.WriteAllBytes(UnityEngine.Application.streamingAssetsPath + "/Temp/temp.png", data);}}}
