推荐答案

如果你发布了一些你尝试过的例子以及为什么没有成功，问题可能会更清楚。



您是否想要删除空行？如果是这样，可以使用一种方式：

The question might be more clear if you posted some examples of what you have tried and why it hasn't succeeded.

Are you trying to remove the empty lines? If so one way would be to use:

string[] lines = File.ReadAllLines("path");

using(var writer = File.AppendText("newpath"))
{		
  foreach(var line in lines)
  {
    if(!String.IsNullOrWhiteSpace(line))
    {
      writer.WriteLine(line);
    }
  } 
}
