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);
}
}
