Question

    proc.MainWindowTitle.Contains("e")

如何使用“MainWindowTitle”获取包含“e”的所有当前窗口的窗口标题而不是主窗口，并将它们存储到字符串数组中？

修改

     string[] toClose = {proc.MainWindowTitle};
                for (int i = 0; i < toClose.Length; i++)
                {
                    string s = toClose[i];
                    int hwnd = 0;

                    hwnd = FindWindow(null, s);

                    //send WM_CLOSE system message
                    if (hwnd != 0)
                        SendMessage(hwnd, WM_CLOSE, 0, IntPtr.Zero);

Answer 1

代码段

string[] result = new string[50];
int count = 0;
Process[] processes = Process.GetProcesses();
foreach(var process in processes)
{
    if (process.MainWindowTitle
               .IndexOf("e", StringComparison.InvariantCulture) > -1)
    {
        result[count] = process.MainWindowTitle;
        count++;
    }
}

如果我理解正确，您想要检索进程主窗口标题列表。

分析下面的代码，toClose变量始终存储一个标题：proc.MainWindowTitle值。

string[] toClose = { proc.MainWindowTitle };

您必须使用原始答案的foreach语句检索每个窗口标题。然后，您必须在建议的解决方案中使用result变量，而不是代码中的toClose变量。

您需要遍历流程列表（可以使用

进行）

Process[] processlist = Process.GetProcesses();）

foreach( Process in processlist )

并将Process.MainWindowTitle写入数组。试试看：）

c＃获取流程窗口标题
