FileSystemInfo为字符串数组

Question

我想知道将FileSystemInfo转换为字符串数组的最有效方法是 - 我的代码如下：

    string[] filePaths;
    DirectoryInfo di = new DirectoryInfo(batchDirectory);
    FileSystemInfo[] files = di.GetFileSystemInfos();
    filePaths = files.OrderBy(f => f.CreationTime); 

我试过了：

filePaths = files.OrderBy(f => f.CreationTime).ToArray; 

但没有运气

Answer 1

试试这个：

filePaths = files.OrderBy(f => f.CreationTime).Select(x => x.FullName).ToArray(); 

Answer 2

将括号（）添加到Array;

 files.OrderBy(f => f.CreationTime).ToArray();
