C# Listview双击无法正常工作

我对这个清单有意见。当我双击它时，它应该会显示一个对话框，显示我所单击行的第一个单元格的信息，这非常好

现在的问题是，如果我一直单击行，我仍然会从前面单击的行中获得对话框

I click a random row 1 time: Shows me dialog
I click another random row: Shows me dialog from the first row I clicked, then when I close said dialog it shows me the dialog of info of the row I clicked.
I click another random row: Shows me dialog from the first row I clicked and from the second one.

。。它还在继续

代码如下：

    private void listViewPlayers_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        string
            pUser = "";

        int
            pID = -1;

        pID = Convert.ToInt32(listViewPlayers.SelectedItems[0].SubItems[0].Text);
        pUser = listViewPlayers.SelectedItems[0].SubItems[1].Text;

        bw.WorkerReportsProgress = true;

        bw.DoWork += new DoWorkEventHandler
        (
            delegate(object o, DoWorkEventArgs args)
            {
                BackgroundWorker b = o as BackgroundWorker;

                pInfo = pInfoClient.DownloadString("get info from web").Trim();
            }
        );

        bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler
        (
            delegate(object o, RunWorkerCompletedEventArgs args)
            {
                if (strcmp(pInfo, "ERROR"))
                {
                    MessageBox.Show("There was an error retrieving user information!\nPlease try again later..", "Error");
                    return;
                }

                string[]
                    iSplit = pInfo.Split(new char[] { (char)'|' }, System.StringSplitOptions.RemoveEmptyEntries);

                playerInfo iInfo = new playerInfo(pUser, pID, iSplit);

                iInfo.ShowDialog();
            }
        );

        bw.RunWorkerAsync();
    }

请原谅我对这个问题的解释，我在这方面做得很糟糕。

您可能遇到了意外的内存泄漏情况

看起来“bw”是一个类变量？如果是这样，您的单击事件会不断向后台工作人员的事件添加新的处理程序，但不会删除处理程序，因此每次鼠标单击事件触发时，它都会通知后台工作人员执行该操作，并且这些事件会触发您以前注册的所有处理程序

您可以尝试每次更新后台工作人员，这将解决问题，或者在DoWork事件中，您可能希望确保取消注册该代理。即

var inlineHandler = new DoWorkEventHandler ( delegate(object o, DoWorkEventArgs args) 
{
    BackgroundWorker b = o as BackgroundWorker;
    pInfo = pInfoClient.DownloadString("get info from web").Trim();
    bw.DoWork -= inlineHandler;

});
bw.DoWork += inlineHandler;

不过，我强烈建议您每次都给这位员工打电话。

谢谢！我添加了

BackgroundWorker bw=newbackgroundworker（）事件内部。现在一切正常。
