如何Directory.Getfiles（）多搜索模式滤镜c＃ [英] How can Directory.Getfiles() multi searchpattern filters c#

问题描述

可能重复：

我有一个字符串数组：

string[] pattern={"*.jpg","*.txt","*.asp","*.css","*.cs",.....};

此字符串模式

string[] dizin = Directory.GetFiles("c:\veri",pattern);

如何将dizin变量C：\veri目录下的文件目录分配？

How dizin variable C:\veri directories under the directory of files assign?

推荐答案

你可以使用这样的东西

string[] extensions = { "jpg", "txt", "asp", "css", "cs", "xml" };

string[] dizin = Directory.GetFiles(@"c:\s\sent", "*.*")
    .Where(f => extensions.Contains(f.Split('.').Last().ToLower())).ToArray();

或使用 FileInfo.Extension String.Split 但可能会较慢

string[] extensions = { ".jpg", ".txt", ".asp", ".css", ".cs", ".xml" };

string[] dizin = Directory.GetFiles(@"c:\s\sent", "*.*")
    .Where(f => extensions.Contains(new FileInfo(f).Extension.ToLower())).ToArray();

或者作为 juharr 提到你也可以使用 System.IO.Path.GetExtension

Or as juharr mentioned you can also use System.IO.Path.GetExtension

string[] extensions = { ".jpg", ".txt", ".asp", ".css", ".cs", ".xml" };

string[] dizin = Directory.GetFiles(@"c:\s\sent", "*.*")
    .Where(f => extensions.Contains(System.IO.Path.GetExtension(f).ToLower())).ToArray();
