C#确定文本文件名

Question

我怎么能改变它来确定其目录本身的文本文件？

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();
    ...
}

Answer 1

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);
}
