C# 如何在给定状态下停止foreach循环

我想退出当前一轮，开始下一轮。怎么做。我不想退出foreach循环，我只想退出当前轮并开始下一轮

使用continue来完成。请参见

使用继续执行此操作。请参见

continue语句将控制权传递给它所在的封闭迭代语句的下一个迭代

下面是continue语句在代码中的外观：

foreach (String host   in hostArray)
{
    string s1 = hostArray[t];
    string s2 = branchArray[t];
    string con_msg;
    t=t+1;
    TcpClient socketForServer;
    try
    {
        socketForServer = new TcpClient(s1, 10);
        con_msg="Connected";
    }
    catch
    {
        ListViewItem item = new ListViewItem();
        item.BackColor = Color.LightGreen;
        item.Text = (s2);
        item.SubItems.Add(s1);
        item.SubItems.Add("Not found");
        listView1.Items.Add(item);
        con_msg = "Not connected";
        // I want to exit this round in here and and start next round  how to do it 
    }

    NetworkStream networkStream = socketForServer.GetStream();
    System.IO.StreamReader streamReader =  new System.IO.StreamReader(networkStream);
    System.IO.StreamWriter streamWriter =new System.IO.StreamWriter(networkStream);
    //code
}

foreach (String host   in hostArray)
{
    string s1 = hostArray[t];
    string s2 = branchArray[t];
    string con_msg;
    t=t+1;
    TcpClient socketForServer;
    try
    {
        socketForServer = new TcpClient(s1, 10);
        con_msg="Connected";
    }
    catch
    {
        ListViewItem item = new ListViewItem();
        item.BackColor = Color.LightGreen;
        item.Text = (s2);
        item.SubItems.Add(s1);
        item.SubItems.Add("Not found");
        listView1.Items.Add(item);
        con_msg = "Not connected";

        continue;
    }

    NetworkStream networkStream = socketForServer.GetStream();
    System.IO.StreamReader streamReader =  new System.IO.StreamReader(networkStream);
    System.IO.StreamWriter streamWriter =new System.IO.StreamWriter(networkStream);
    //code
}

goto语句将程序控件直接传输到带标签的语句

下面是goto语句在代码中的外观：

foreach (String host   in hostArray)
{
    string s1 = hostArray[t];
    string s2 = branchArray[t];
    string con_msg;
    t=t+1;
    TcpClient socketForServer;
    try
    {
        socketForServer = new TcpClient(s1, 10);
        con_msg="Connected";
    }
    catch
    {
        ListViewItem item = new ListViewItem();
        item.BackColor = Color.LightGreen;
        item.Text = (s2);
        item.SubItems.Add(s1);
        item.SubItems.Add("Not found");
        listView1.Items.Add(item);
        con_msg = "Not connected";
        // I want to exit this round in here and and start next round  how to do it 
    }

    NetworkStream networkStream = socketForServer.GetStream();
    System.IO.StreamReader streamReader =  new System.IO.StreamReader(networkStream);
    System.IO.StreamWriter streamWriter =new System.IO.StreamWriter(networkStream);
    //code
}

foreach (String host   in hostArray)
{
    string s1 = hostArray[t];
    string s2 = branchArray[t];
    string con_msg;
    t=t+1;
    TcpClient socketForServer;
    try
    {
        socketForServer = new TcpClient(s1, 10);
        con_msg="Connected";
    }
    catch
    {
        ListViewItem item = new ListViewItem();
        item.BackColor = Color.LightGreen;
        item.Text = (s2);
        item.SubItems.Add(s1);
        item.SubItems.Add("Not found");
        listView1.Items.Add(item);
        con_msg = "Not connected";

        continue;
    }

    NetworkStream networkStream = socketForServer.GetStream();
    System.IO.StreamReader streamReader =  new System.IO.StreamReader(networkStream);

使用“继续”在完成捕获之前退出当前回合。。。 通过在catch中使用continue语句，continue和foreach主体末尾之间的语句应该被跳过。例如。。。这就像哈布詹给我的

foreach (var item in Items)
{           
  try
  {
    //Exception
  }
  catch (Exception)
  {
    continue;//Will move to next item of "Items" of FOREACH LOOP
  }

  int a = 1 + 1;//If exception gets this line will not execute
 }

在goto示例中，您必须有另一个标签，因为erroroccurrend将在//代码完成时执行。我不确定使用goto是否是最佳选择。也许使用错误标志bool是更好的选择，然后在末尾使用if标志来选择正确的代码路径。@默认情况下，是的，这就是goto语句的要点。。我只提供了两种可能的解决方案。在他的例子中，continue语句更优雅。在goto示例中，您必须有另一个标签，因为erroroccurrend将在//代码完成时执行。我不确定使用goto是否是最佳选择。也许使用错误标志bool是更好的选择，然后在末尾使用if标志来选择正确的代码路径。@默认情况下，是的，这就是goto语句的要点。。我只提供了两种可能的解决方案。就他的情况而言，continue语句更为优雅。
