Unity对资源管理器操作 打开资源管理器选择文件并筛选文件

打开资源管理器

Application.OpenURL(path);

打开选择文件 筛选文件类型（只要type类型的文件显示）

public void Openfile(string type){OpenFileDlg pth = new OpenFileDlg();pth.structSize = System.Runtime.InteropServices.Marshal.SizeOf(pth);pth.filter = "文件(*." + type + ")\0*." + type + "";//筛选文件类型//pth.filter = "图片文件(*.jpg*.png)\0*.jpg;*.png";pth.file = new string(new char[256]);pth.maxFile = pth.file.Length;pth.fileTitle = new string(new char[64]);pth.maxFileTitle = pth.fileTitle.Length;pth.initialDir = Application.streamingAssetsPath.Replace('/', '\\'); // default pathpth.title = "选择项目json";pth.defExt = "JPG";//显示文件类型pth.flags = 0x00080000 | 0x00001000 | 0x00000800 | 0x00000200 | 0x00000008;if (OpenFileDialog.GetOpenFileName(pth)){string filepath = pth.file;//选择的文件路径;DirectoryInfo i = new DirectoryInfo(filepath);//上级目录string path = i.Parent.FullName;//返回文件的上级目录ProjectData openprodata = new ProjectData();openprodata.proname = Path.GetFileNameWithoutExtension(path);//返回路径的最后一个文件夹名称}

调用的是openfileDgl 搬走不谢
