    UNITY3D中设置文件选择框选择路径和文件名范例

    UNITY3D中设置文件选择框的范例:


    using OpenWinForm = System.Windows.Forms;
    在unity3d中,使用FileDialog应该把System.Windows.Forms.dll拷贝到unity工程的plugins目录,
    并且把Player Setting中Other Settings下的api compatibility Level改为.NET2.0。要不无法编译通过。
    //比如unity3d要让用户选择某一个音乐文件播放;
    private void SelectMusic(){
            OpenWinForm.OpenFileDialog op = new OpenWinForm.OpenFileDialog();
            op.Title = "音乐";
            op.Filter = "音频文件(*.wav;*.ogg)|*.wav;*.ogg";
            if (op.ShowDialog() == OpenWinForm.DialogResult.OK || op.ShowDialog() == OpenWinForm.DialogResult.Yes)
            {
                string selectName = op.FileName;
                customBgmPath.text = selectName;
    
                string path = customBgmPath.text;      
                WWW www = new WWW("file://"+path);
                if(www.audioClip){
                    AudioClip clip = www.audioClip;
                    AudioPlayCtr.instance.ChangeBgMusic(clip);
                }
    
            }
            else {
                return;
            }
        }
    
     
    
        //自定义文件保存文件夹;
        private void SaveCutScreenPath()
        {
            OpenWinForm.FolderBrowserDialog fb = new OpenWinForm.FolderBrowserDialog();
            fb.ShowNewFolderButton = true;
            fb.RootFolder = Environment.SpecialFolder.MyDocuments;
            fb.SelectedPath = "C:";
            fb.Description = "请选择截图保存目录";
            fb.RootFolder = Environment.SpecialFolder.MyDocuments;
            if (fb.ShowDialog() == OpenWinForm.DialogResult.OK || fb.ShowDialog() == OpenWinForm.DialogResult.Yes)
            {
                string selectName = fb.SelectedPath;
                customCutScreenPath.text = selectName;
            }
            else {
                return;
            }
        }
    
     
    
    //比如unity3d截图后,弹出对话框用户选择保存路径;
    
    public IEnumerator CutScreent() {
            int width = Screen.width;
            int height = Screen.height;
            yield return new WaitForEndOfFrame(); 
            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);
    
            OpenWinForm.SaveFileDialog saveFileDialog = new OpenWinForm.SaveFileDialog();
            saveFileDialog.Filter = "图像文件(*.png)|*.png";
            saveFileDialog.FilterIndex = 2;
            saveFileDialog.RestoreDirectory = true;
            if (saveFileDialog.ShowDialog() == OpenWinForm.DialogResult.OK)
            {
                string fName = saveFileDialog.FileName;
                Stream flstr = new FileStream(fName, FileMode.Create);//文件操作
                BinaryWriter sw = new BinaryWriter(flstr, System.Text.Encoding.Unicode);
                sw.Write(bytes);
                sw.Close();
                flstr.Close();
            }
        }
