本文将和大家介绍如何在 dotnet C# 里面使用 SHFileOperation 调用 Windows 自带的文件复制对话框进行文件复制
本文核心代码拷贝自 C#中使用SHFileOperation调用Windows的复制文件对话框 - 季风哥 - 博客园 文章，特别感谢大佬提供的方法
实现的效果图如下
详细实现逻辑还请大家参阅： C#中使用SHFileOperation调用Windows的复制文件对话框 - 季风哥 - 博客园
其中我遇到的坑是多个文件之间需要使用 \0 字符分割，我使用了 dotnet 新 API 对其进行更新，代码如下
pm.pFrom = string.Join(FILE_SPLITER, sourceFiles) + $"{FILE_SPLITER}{FILE_SPLITER}";pm.pTo = string.Join(FILE_SPLITER, targetFiles) + $"{FILE_SPLITER}{FILE_SPLITER}";
上述代码的 FILE_SPLITER 和 pm 都是从 C#中使用SHFileOperation调用Windows的复制文件对话框 博客里面抄的
所有代码如下

本文代码放在 github 和 gitee 上，可以使用如下命令行拉取代码。我整个代码仓库比较庞大，使用以下命令行可以进行部分拉取，拉取速度比较快
先创建一个空文件夹，接着使用命令行 cd 命令进入此空文件夹，在命令行里面输入以下代码，即可获取到本文的代码
git init
git remote add origin https://gitee.com/lindexi/lindexi_gd.git
git pull origin 9685aaf325b6d7deee15fd6488cd7533f7052ea2
以上使用的是国内的 gitee 的源，如果 gitee 不能访问，请替换为 github 的源。请在命令行继续输入以下代码，将 gitee 源换成 github 源进行拉取代码。如果依然拉取不到代码，可以发邮件向我要代码
git remote remove origin
git remote add origin https://github.com/lindexi/lindexi_gd.git
git pull origin 9685aaf325b6d7deee15fd6488cd7533f7052ea2
获取代码之后，进入 Workbench/KachelearnemChurjawenikall 文件夹，即可获取到源代码
