本文實例為大家分享了Unity3D選擇本地圖片并加載的具體代碼，供大家參考，具體內(nèi)容如下

①找到System.Windows.Forms.dll：在unity的安裝目錄中找到它，如

E:/ProgramFiles(x86)/Unity/Editor/Data/Mono/lib/mono/2.0

②設(shè)置.NET 2.0集：Untiy默認(rèn)是.NET 2.0 Subset。在Edit->Project Settings->Player->OtherSettings中修改

③任意打開一項目，新建Plugins文件夾，將找到的System.Windows.Forms.dll復(fù)制進去工程文件中(Project)

using UnityEngine;using System.Collections;using System;using System.Windows.Forms;using System.IO;using UnityEngine.UI;public class AddHead : MonoBehaviour { private Texture2D img=null; public Image image; public Sprite sprite;// 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), "選擇文件")) { }*/ public void addhead(){ OpenFileDialog od=new OpenFileDialog(); od.Title="請選擇頭像圖片"; od.Multiselect=false; od.Filter="圖片文件(*.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); image.sprite=sprite; }*/ } IEnumerator GetTexture(string url){ WWW www = new WWW (url); yield return www; if (www.isDone && www.error == null) { img=www.texture; sprite=Sprite.Create(img,new Rect(0,0,img.width,img.height),new Vector2(0.5f,0.5f));  image.sprite=sprite; //Debug.Log(img.width+" "+img.height); byte[] date=img.EncodeToPNG(); } }}

為按鈕綁定一個addhead()的方法
