c# 获取 LINQ 语句中的最后一个元素

Question

    var filePaths = Directory.GetFiles(@"\\Pontos\completed\", "*_*.csv").Select(p => new { Path = p, Date = System.IO.File.GetLastWriteTime(p) })
        .OrderBy(x => x.Date)
        .Where(x => x.Date >= LastCreatedDate);

我想知道最近的x.Date

的值

如何从这个 linq 语句中获取最新日期？

请注意，我不需要文件路径，而是需要DATE

Answer 1

var mostRecent = Directory.GetFiles(@"\\Pontos\completed\", "*_*.csv")
    .Select(p => new { Path = p, Date = System.IO.File.GetLastWriteTime(p) }) 
    .OrderBy(x => x.Date) 
    .Where(x => x.Date >= LastCreatedDate)
    .LastOrDefault(); 

或

var mostRecent = Directory.GetFiles(@"\\Pontos\completed\", "*_*.csv")
    .Select(p => new { Path = p, Date = System.IO.File.GetLastWriteTime(p) }) 
    .OrderByDescending(x => x.Date) 
    .Where(x => x.Date >= LastCreatedDate)
    .FirstOrDefault();
