C＃列表框被划分到另一2个列表框

Question

问题： 我已经它加载的文本文件1个列表框包含：

• IP：端口
• IP：端口
• IP：端口

我想要做的是，一旦我将文本文件加载到列表框中，我想让'ip'进入不同的列表框，将'port'放入不同的列表框中。这是第一次处理这样的项目。

 using (StreamReader sr = new StreamReader("TestFile.txt")) 
     { 
      String line; 
      // Read and display lines from the file until the end of 
      // the file is reached. 
      while ((line = sr.ReadLine()) != null) 
      { 
       string[] ipandport = line.split(":"); 
       lstBoxIp.Items.Add(ipandport[0]); 
       lstBoxPort.Items.Add(ipandport[1]); 
      } 
     } 

Answer 2

// if you wanted to do it with LINQ. 
// of course you're loading all lines 
// into memory at once here of which 
// you'd have to do regardless 
var text = File.ReadAllLines("TestFile.txt"); 
var ipsAndPorts = text.Select(l => l.Split(':')).ToList(); 

ipsAndPorts.ForEach(ipAndPort => 
{ 
    lstBoxIp.Items.Add(ipAndPort[0]); 
    lstBoxPort.Items.Add(ipAndPort[1]); 
});
