文件夹下所有文件按修改时间 排序

基础类

public class FIleLastTimeComparer : IComparer<FileInfo>

{

#region IComparer<FileInfo> 成员

public int Compare(FileInfo x, FileInfo y)

{

return x.LastWriteTime.CompareTo(y.LastWriteTime);

}

#endregion

}

另一个类

FileInfo[] file = new FileInfo[recDatafiles.Length];

for (int i = 0; i < recDatafiles.Length; i++)

{

file[i] = new FileInfo(recDatafiles[i]);

}

Array.Sort<FileInfo>(file, new FIleLastTimeComparer());
