先放个效果图:
首先需要定义一个OpenFileName的类:
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)] public class OpenFileName { public int structSize = 0; public IntPtr dlgOwner = IntPtr.Zero; public IntPtr instance = IntPtr.Zero; public String filter = null; public String customFilter = null; public int maxCustFilter = 0; public int filterIndex = 0; public String file = null; public int maxFile = 0; public String fileTitle = null; public int maxFileTitle = 0; public String initialDir = null; public String title = null; public int flags = 0; public short fileOffset = 0; public short fileExtension = 0; public String defExt = null; public IntPtr custData = IntPtr.Zero; public IntPtr hook = IntPtr.Zero; public String templateName = null; public IntPtr reservedPtr = IntPtr.Zero; public int reservedInt = 0; public int flagsEx = 0; }
当然,也不是都用到了,只用到了一小部分,有性趣的童鞋可以个性化一下保存对话框,
然后是最重要的委托GetSaveName()方法:
public class DllUse { [DllImport("Comdlg32.dll", SetLastError = true, ThrowOnUnmappableChar = true, CharSet = CharSet.Auto)] public static extern bool GetSaveFileName([In, Out] OpenFileName ofn); }
挡挡挡,最后调用一下即可:
public static void OpenDialog(ActiononSave) { OpenFileName ofn = new OpenFileName(); ofn.structSize = Marshal.SizeOf(ofn); ofn.filter = "Excel (*.xls)\0*.xls\0\0"; ofn.file = new string(new char[256]); ofn.maxFile = ofn.file.Length; ofn.fileTitle = new string(new char[64]); ofn.maxFileTitle = ofn.fileTitle.Length; ofn.initialDir = UnityEngine.Application.dataPath;//默认路径ofn.title = "保存文件"; ofn.defExt = ".xls";//显示文件的类型ofn.flags = 0x00080000 | 0x00001000 | 0x00000800 | 0x00000200 | 0x00000008;if (DllTest.GetSaveFileName(ofn)) { dosomething();string Savepath = Path.GetDirectoryName (ofn.file); Process.Start (Savepath); } }
