I have removed the Spaces to one Space and want to split the File with this to add evrything under Name Pid and so on to a GridviewColumn every line is a extra line in the GridViewColumn how I can solve this to add evry line to a GridViewColumn:
我已将 Spaces 删除到一个 Space，并想用这个拆分文件以将 Name Pid 下的所有内容添加到 GridviewColumn 中，每一行都是 GridViewColumn 中的一个额外行，我如何解决这个问题以将 evry 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; }
}

There are a couple tasks involved in this:
这涉及到几个任务：
- Read the text file into objects
- Display those objects in a
GridView
- 将文本文件读入对象
- 将这些对象显示在
GridView
The first isn't too bad. First we need a class to store everything in:
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; }
}
Then we need to parse the text file:
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);
}
}
Finally, we need to set up the XAML:
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>
Bind each column to a property in the ProcessInfoclass. I included a sample for the first column. Of course, you need to expose the parsed collection as a public property of your View Model for this to work.
将每一列绑定到ProcessInfo类中的一个属性。我在第一列中包含了一个示例。当然，您需要将解析后的集合公开为您的视图模型的公共属性才能使其工作。

For spliting you can use regex.
对于拆分，您可以使用正则表达式。
e.g.
例如
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];
...
