推荐答案

假设这是您要显示的chm文件，则应使用System.Windows.Forms.Help

因此，请听一个按键，并显示您的chm文件:

Assuming it is a chm-file you want to show, you should use System.Windows.Forms.Help

So listen to a key stroke, and show your chm-file:

void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.H)
        Help.ShowHelp(this, "my.chm");
}

如果您想在全球范围内聆听按键，则可以查看以下内容:
