C# 将数据加载到Listview（WPF）

我正在尝试制作一个重复的文件检测器（相关问题：）。我的总体结构如下：

扫描目录并将每个文件所需的详细信息加载到DupInfo对象中

计算与其他文件大小匹配的任何文件的CRC

显示任何具有匹配大小和CRC（以及可选的基本目录）的文件，并允许用户检查要删除的文件（手动和使用“检查所有第一个副本”之类的按钮）

删除所选文件

我在第三步遇到了问题。步骤1和2中的数据位于DupInfo对象列表中。下面是类定义

public class DupInfo
    {
        public string FullName { get; set; }
        public long Size { get; set; }
        public uint? CheckSum { get; set; }
        public string BaseDirectory { get; set; }
        public DupInfo(FileInfo file, Crc32 crc, int level)
        {
            FullName = file.FullName;
            Size = file.Length;
            CheckSum = crc.ComputeChecksum(File.ReadAllBytes(FullName));
            BaseDirectory = FullName.Substring(0,FullName.NthIndexOf("\\",level));
        }
        public DupInfo(FileInfo file, int level)
        {
            FullName = file.FullName;
            Size = file.Length;
            BaseDirectory = FullName.Substring(0, FullName.NthIndexOf("\\", level));
        }

    }

我的问题是:

从自定义类（DupInfo）列表将数据加载到Listview对象的最佳方式是什么

如果Listview不是显示重复集的最佳工具，那么什么是最佳工具

---

我将使用绑定到

可观察集合的数据网格

结果:


更新1:

我们没有可用的AddRange，但为此定义了扩展方法：

public static class ExtensionMethods
{
    public static void AddRange(this ObservableCollection<DupInfo> value, List<DupInfo> list)
    {
        foreach (var dup in list)
            value.Add(dup);
    }
}

就这样。祝你好运
 谢谢你，我喜欢这个主意。我想知道如何将DupInfo列表转换为“items”对象。是否有addrange或copyto方法可用于ObservableCollection？或者我可以将ItemsSource设置为某个值。我应该将项设置为一个LINQ查询来转换数据吗？事实上，在进一步查看代码之后，我想我误解了。它看起来不需要任何转换，但将直接显示来自DupInfo对象的DupInfo字段。对吗？如果是，如何添加整个dupInfos列表？我可以使用AddRange（）来执行此操作吗？@KalevMaricq DataGrid有一个默认为true的属性名AutoGenerateColumns。如果保持这样，就不需要其他转换。但是，如果要为列定义模板，请将其设置为false，然后在此处查看如何定义DataGridTemplateColumn。@KalevMaricq是的，AddRange扩展应该可以为您完成此工作。谢谢。我试着走这条路。如何添加复选框，以便用户可以指示要删除的文件？
