【问题描述】:
我使用以下代码为 WinForm 应用程序分配控制台。控制台窗口成功显示并且输出在那里。但是当我关闭控制台窗口时,我的 WinForm 应用程序同时关闭。为什么?我想保留 WinForm 窗口。
private void btn_to_console_Click(object sender, EventArgs e)
{
if (NativeMethods.AllocConsole())
{
lbl_console_alloc_result.Text = "Console allocation successfully!";
IntPtr stdHandle = NativeMethods.GetStdHandle(NativeMethods.STD_OUTPUT_HANDLE);
Console.WriteLine("from WinForm to Console!");
lbl_console_alloc_result.Text = Console.ReadLine();
}
else
lbl_console_alloc_result.Text = "Console allocation failed!";
}
[System.Runtime.InteropServices.DllImportAttribute("kernel32.dll", EntryPoint = "GetStdHandle")]
public static extern System.IntPtr GetStdHandle(Int32 nStdHandle);
/// Return Type: BOOL->int
[System.Runtime.InteropServices.DllImportAttribute("kernel32.dll", EntryPoint = "AllocConsole")]
[return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)]
public static extern bool AllocConsole();
提前谢谢...
