Unity Windows选择图片并加载_unity editorwindow 中如何加载图集中的子图

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);
		}
	}
}
