我已经将空格删除到一个空间，并希望将文件与此分开，以添加名称Pid等下的所有内容到GridviewColumn每一行都是GridviewColumn中的额外行，我如何解决这个问题以将每一行添加到GridviewColumn:

RegexOptions options = RegexOptions.None;
            Regex regex = new Regex(@"[ ]{2,}", options);
            string fs = regex.Replace(s, @" ");
          var fs1 = fs.Split(' ',''n');



     _GameCollection.Add(new GameData { 
      Name = fs1[18],
      PID = fs1[19],
      CPU = fs1[20],
      Thd = fs1[21],
      Hnd = fs1[22],
      CpuTime = fs1[23],
      ElapsedTime = fs1[24]
     });
         _GameCollection.Add(new GameData
         {
         });
    }

    public ObservableCollection<GameData> GameCollection
    { get { return _GameCollection; } }

}
public class GameData
{
    public string Name { get; set; }
    public string PID { get; set; }
    public string CPU { get; set; }
    public string Thd { get; set; }
    public string Hnd { get; set; }
    public string CpuTime { get; set; }
    public string ElapsedTime { get; set; }
}

c# WPF逐行读取.txt文件，并将其存储到listview中

这里涉及到几个任务:

  1. 将文本文件读入对象
  2. 在GridView
    3. 中显示这些对象

第一个还不错。首先，我们需要一个类来存储所有内容:

public class ProcessInfo
{
    public string Name { get; set; }
    public int PID { get; set; }
    public int CPU { get; set; }
    public int Thd { get; set; }
    public int Hnd { get; set; }
    public TimeSpan CpuTime { get; set; }
    public TimeSpan ElapsedTime { get; set; }
}

然后我们需要解析文本文件:

List<ProcessInfo> processes = new List<ProcessInfo>();
using(StreamReader reader = new StreamReader("input.txt'))
{
    reader.ReadLine(); //The headers don't matter!
    string currentLine;
    while (currentLine = reader.ReadLine() != null)
    {
        ProcessInfo newInfo = new ProcessInfo();
        //Actual parsing left up to the reader; String.Split is your friend.
        processes.Add(newInfo);
    }
}
最后，我们需要设置XAML: 
<ListView ItemsSource="{Binding Processes}">
    <ListView.View>
        <GridView>
            <GridViewColumn DisplayMemberBinding="{Binding Name}" Header="Name"/>
          ...
        </GridView>
    </ListView.View>
</ListView>

将每个列绑定到ProcessInfo类中的一个属性。我在第一栏里放了一个样本。当然，您需要将解析后的集合公开为视图模型的公共属性。

可以使用正则表达式进行分割。

。

string inputLine = "Idle                  0  99   8    0      0   203:18:16.647    26:02:53.315";
string[] splitList = Regex.Split (inputLine, "''s{1,30}");
string name = splitList [0];
string pid = splitList [1];
string CPU = splitList [2];
...
