unity3d各种OpenFileDialog操作
1 编辑模式（Editor）下：
string path = EditorUtility.OpenFilePanel("Load png Textures of Directory", "", "");
WWW ww=new WWW("file:///"+path);
print(ww.url);
yield return ww;
gui.texture=ww.texture;
2.非编辑模式：
OpenFileDialog ofd = new OpenFileDialog(); //new一个方法
ofd.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments); // 定义打开的默认文件夹位置
if(ofd.ShowDialog()==DialogResult.OK)
{
//显示打开文件的窗口
Debug.Log( ofd.FileName);
}
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.net 2.0 Subset为.net2.0 但是不知道什么原因，会频繁的崩溃。
