一次写入多个文本文件

您可以使用流编写器列表并使用 Parallel.Foreach 以同时写入多个文件。

var streamWriters = new List<StreamWriter>();
streamWriters.Add(new StreamWriter("1.txt"));
streamWriters.Add(new StreamWriter("2.txt"));
streamWriters.Add(new StreamWriter("3.txt"));
streamWriters.Add(new StreamWriter("4.txt"));
streamWriters.Add(new StreamWriter("5.txt"));
streamWriters.Add(new StreamWriter("6.txt"));

Parallel.ForEach(streamWriters, s => { s.Write("some text"); s.Dispose(); });

这可能会提高一些性能。
