如何在 c# 中使用 user32.dll 从类“ThunderRT6ListBox”的窗口中检索值

我正在尝试从Windows中的外部桌面应用程序中检索信息。

我知道如何从

文本框中提取文本（类"编辑"），但我不知道如何从类名为"ThunderRT6ListBox"和"ThunderRT6ComboBox"的控件中提取值。我该怎么做？

我有以下代码从文本框中提取文本：

public static class ModApi
{
    [DllImport("user32.dll", EntryPoint = "FindWindowA", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
    public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
    [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
    public static extern int GetClassName(IntPtr hWnd, StringBuilder lpClassName, int nMaxCount);
    [DllImport("user32.dll", EntryPoint = "SendMessageTimeout", SetLastError = true, CharSet = CharSet.Auto)]
    public static extern uint SendMessageTimeoutText(IntPtr hWnd, int Msg, int countOfChars, StringBuilder text, uint flags, uint uTImeoutj, uint result);
    [DllImport("user32.dll", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
    static internal extern bool EnumChildWindows(IntPtr hWndParent, funcCallBackChild funcCallBack, IntPtr lParam);
    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
    static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, StringBuilder lParam);
    const int LB_GETCOUNT = 0x018B;
    const int LB_GETTEXT = 0x0189;
    public static string GetText(IntPtr hwnd)
    {
        var text = new StringBuilder(1024);
        if (SendMessageTimeoutText(hwnd, 0xd, 1024, text, 0x2, 1000, 0) != 0)
        {
            return text.ToString();
        }
        return "";
    }        
}

public foo()
{
     IntPtr value = new IntPtr(0x019C086A); //ID locate using Spy++
     String caption = ModApi.GetText(value);
}

更新 1：

从列表框读取的方法：

    public static List<string> GetListBoxContents(IntPtr listBoxHwnd)
    {
        int cnt = (int)SendMessage(listBoxHwnd, LB_GETCOUNT, IntPtr.Zero, null);
        List<string> listBoxContent = new List<string>();
        for (int i = 0; i < cnt; i++)
        {
            StringBuilder sb = new StringBuilder(256);
            IntPtr getText = SendMessage(listBoxHwnd, LB_GETTEXT, (IntPtr)i, sb);
            listBoxContent.Add(sb.ToString());
        }
        return listBoxContent;
    }

更新 2：

从组合框读取的方法：

    public static List<string> GetComboBoxContents(IntPtr cbBoxHwnd)
    {
        int cnt = (int)SendMessage(cbBoxHwnd, CB_GETCOUNT, IntPtr.Zero, null);
        List<string> listBoxContent = new List<string>();
        for (int i = 0; i < cnt; i++)
        {
            //int txtLength = SendMessage(cbBoxHwnd, CB_GETLBTEXTLEN, i, 0); 
            StringBuilder sb = new StringBuilder(256);
            IntPtr getText = SendMessage(cbBoxHwnd, CB_GETLBTEXT, (IntPtr)i, sb);
            listBoxContent.Add(sb.ToString());
        }
        return listBoxContent;
    }
