unity 选择系统路径并导出excel

首先，网上一搜一大堆，但是大多都千篇一律不实用，本文章主要实现功能，将数据存储为excel，选择系统另存为路径，导出excel。

该功能都实现在一个脚本之内，首先需要引用以下内容:

需引用内容

接下来需要实现3个类，首先是数据接收类

[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;

}

接下来是系统函数调用类

public class LocalDialog

{

    //链接指定系统函数 打开文件对话框

    [DllImport("Comdlg32.dll", SetLastError = true, ThrowOnUnmappableChar = true, CharSet = CharSet.Auto)]

    public static extern bool GetOpenFileName([In, Out] OpenFileName ofn);

    public static bool GetOFN([In, Out] OpenFileName ofn)

    {

        return GetOpenFileName(ofn);

    }

    //链接指定系统函数 另存为对话框

    [DllImport("Comdlg32.dll", SetLastError = true, ThrowOnUnmappableChar = true, CharSet = CharSet.Auto)]

    public static extern bool GetSaveFileName([In, Out] OpenFileName ofn);

    public static bool GetSFN([In,Out] OpenFileName ofn)

    {

        return GetSaveFileName(ofn);

    }

}

最后是讲数据写入文件并存成excel，同时存入后还会打开存入的文件夹可以直接查看

写入excel 并导出

需要注意的是写excel需要 EPPlus.dll;

这个网上有很多，随便下一个就哦了
