GJM: Unity3d打开对话框

编辑模式（Editor）下：


string path = EditorUtility.OpenFilePanel("Load png Textures of Directory", "", "");
WWW www = new WWW("file:///" + path);
Debug.Log(www.url);
yield return www;
ure = ure;

非编辑模式


OpenFileDialog diglog = new OpenFileDialog();
diglog.InitialDirectory = "file://" + UnityEngine.Application.dataPath;  //定义打开的默认文件夹位置//定义打开的默认文件夹位置
if(ofd.ShowDialog() == DialogResult.OK)
{// todo: 显示打开文件的窗口Debug.Log(ofd.FileName);
}

注意: 以上操作需要添加 System.Windows.Forms.dll,放在Plugins文件夹下，同时需要更改 2.0 Subset为2.0
