void OnGUI(){

        if(GUI.Button(new Rect(10,70,50,50),"ScreenShot")){
                    StartCoroutine(ScreenShot());  //协程调用
        }
    }

    IEnumerator ScreenShot(){
            int width = Screen.width;
            int height = Screen.height;
            yield return new WaitForEndOfFrame(); //去掉协程试试看会发生什么。
            Texture2D tex = new Texture2D(width,height,TextureFormat.RGB24,false);//设置Texture2D
            tex.ReadPixels(new Rect(0,0,width,height),0,0);//获取Pixels
            tex.Apply();//应用改变
            byte[] bytes = tex.EncodeToPNG();//转换为byte[]
　　　　　　　Destroy(tex);
            Stream flstr = new FileStream(@"d:\1.png", FileMode.Create);//文件操作
            BinaryWriter sw = new BinaryWriter(flstr, Encoding.Unicode);
            sw.Write(bytes);
            sw.Close();
            flstr.Close();    

    }

　　另一种方法：

using UnityEngine; 

using System.Collections;

public class example : MonoBehaviour 

{ 

　　void OnMouseDown() 

　　{ 

　　　　Application.CaptureScreenshot("Screenshot.png"); 

　　} 

}

function OnGUI(){
    if(GUI.Button(Rect(Screen.width*0.5-,Screen.height*0.5-,,),"screen")){
        Application.CaptureScreenshot("Screenshot.png");
    }
 }

这张Screenshot.png图片被存在了当前工程的子目录下了。
