# NCMDumpGUI

> [!CAUTION]
> 此应用只用于学习用途，禁止用于商业或违法用途，请在遵守NCM文件提供平台的服务条款下使用本应用，作者对商业或违法使用本软件造成的任何后果不承担任何责任！
这是一个简单程序，使用到了 `ncmdump` 项目实现 ncm 解密功能

适用于对命令行一问三不知的小白用户

本项目使用 .NET 8 和 C# WinForm 编写，主体代码为 `ncmdump` 的示例，本项目只是写了一个用户界面

## 特点

- 小体积
- 低内存占用
- 功能强悍
- 开箱即用

## 下载

请在 [Releases](https://github.com/WhatDamon/NCMDumpGUI/releases) 页面下载最新版本

注意请提前安装好 .NET 8 运行时，点击[此处](https://windows.net)前往官网

仅适用于 Windows 平台
仅适用于 Windows 平台，系统支持详见[此处](https://github.com/dotnet/core/blob/main/release-notes/8.0/supported-os.md#Windows)

如果您正在使用 Windows 不受支持，可以修改项目属性 .NET 版本为 .NET 6 以获得对 Windows 7、8.1 等版本的支持

## TODO

- [x] 基本用户界面
- [x] 异常处理
- [x] 批量处理
- [ ] 更详细的状态信息
- [ ] 批量处理
- [ ] 导出位置选择

## 鸣谢
