如何实现Unity C# GetSaveFileName()？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

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(Action<Stream> onSave) { 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); } }
