c# - 按创建顺序获取文件列表

Question

我当前正在将不同目录中的文件列表读入列表中:

public List<string> MapMyFiles()
        {
            List<string> batchaddresses = new List<string>();
            foreach (object o in lstViewAddresses.Items)
            {
                try
                {
                    batchaddresses.AddRange(Directory.GetFiles(o.ToString(), "*-E.esy"));
                }
                catch
                {
                    if (MessageBox.Show(o.ToString() + " does not exist. Process anyway?", "Continue?", MessageBoxButtons.YesNo)
                        == DialogResult.Yes) { }
                    else
                    {
                        Application.Exit();
                    }
                }

            }

我如何在列表中按创建日期对它们进行排序？

Answer 1

尝试使用 FileInfo 对象并按 CreationTime 属性排序，然后将其作为 FullName (即路径)返回

public List<string> MapMyFiles()
{
    List<FileInfo> batchaddresses = new List<FileInfo>();
    foreach (object o in lstViewAddresses.Items)
    {
        try
        {
            string[] files = Directory.GetFiles(o.ToString(), "*-E.esy");
            files.ToList().ForEach(f => batchaddresses.Add(new FileInfo(f)));
        }
        catch { }
    }

    return batchaddresses.OrderBy(f => f.CreationTime).Select(f => f.FullName).ToList();
}
