C＃确定文本文件名(C# determining text file names)

我怎么能改变它来确定其目录中的文本文件？

string[] file = new string[] { "abc", "def", "file3"}; var files = (UInt16)file.Length; for (UInt16 n = 0; n < files; n++) { var streamReader = new System.IO.StreamReader( file[n] + ".txt"); ... streamReader.Close(); ... }

How could I change this to determine the text files in its directory itself?

string[] file = new string[] { "abc", "def", "file3"}; var files = (UInt16)file.Length; for (UInt16 n = 0; n < files; n++) { var streamReader = new System.IO.StreamReader( file[n] + ".txt"); ... streamReader.Close(); ... }

最满意答案

string[] files = Directory.GetFiles(@"c:\MyDir\", "*.txt");

更新一些用法：

foreach (var filename in files) { string allText = File.ReadAllText(filename); // or string[] lines = File.ReadLines(filename); } string[] files = Directory.GetFiles(@"c:\MyDir\", "*.txt");

Update Some usage:

foreach (var filename in files) { string allText = File.ReadAllText(filename); // or string[] lines = File.ReadLines(filename); }
