唉哟，这次厉害咯，网上搜罗了好久，终于被我找到汉化的保存对话框了，根据网上的一些前辈总结的内容，做了一些修改，

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);
        }
    }
