Unity C# GetSaveFileName()的实例详解

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(ActionStream>
 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);
        }
    }
    

终于搞定保存对话框汉化了，5555，也是不容易啊！

那位小伙伴有更好的方法希望可以分享给我啊！
