如何通过调用 Windows“复制文件”对话框来复制文件？
SHFileOperation似乎是一种选择，但它在我们的流程中。
顺便问一下，SHFileOperation有GUI界面吗？它与 Windows 复制对话框完全相同吗？

是的，这就是该SHFileOperation功能的设计目的。它接受一个SHFILEOPSTRUCT结构作为其唯一参数，您可以使用它来指定所需的选项。
但是，它已在 Windows Vista 和更高版本中被替换为该IFileOperation界面。

是的。SHFileOperation您可以按照此处的示例进行pinvoke ：
using System;
using System.Windows;
using System.Runtime.InteropServices;
namespace WpfApplication2
{
public class InteropSHFileOperation
{
public enum FO_Func : uint

}

是的，SHFileOperation为相应的文件操作显示默认的 shell 对话框，当你调用它时你可以控制它。
