Can you call Directory.GetFiles() with multiple filters?
我有一个字符串数组:
string[] pattern={"*.jpg","*.txt","*.asp","*.css","*.cs",.....};
这个字符串模式
string[] dizin = Directory.GetFiles("c:\veri",pattern);
dizin变量C:\veri目录下的文件如何赋值？
最佳答案
你可以用这样的东西
string[] extensions = { "jpg", "txt", "asp", "css", "cs", "xml" };
string[] dizin = Directory.GetFiles(@"c:\s\sent", "*.*")
.Where(f => extensions.Contains(f.Split('.').Last().ToLower())).ToArray();
或者使用 FileInfo.Extension 比 String.Split 更安全但可能更慢
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();
或者如 juharr 所述，您还可以使用 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();
关于c# - Directory.Getfiles() 多个搜索模式过滤器如何 c#，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14330295/
