PHP实战：C# WinForm中实现快捷键自定义设置实例

private void keyDown(object sender, KeyEventArgs e)
{
    StringBuilder keyValue = new StringBuilder();
    keyValue.Length = 0;
    keyValue.Append("");
    if (e.Modifiers != 0)
    {
        if (e.Control)
            keyValue.Append("Ctrl + ");
        if (e.Alt)
            keyValue.Append("Alt + ");
        if (e.Shift)
            keyValue.Append("Shift + ");
    }
    if ((e.KeyValue >= 33 && e.KeyValue <= 40) ||
        (e.KeyValue >= 65 && e.KeyValue <= 90) ||   //a-z/A-Z
        (e.KeyValue >= 112 && e.KeyValue <= 123))   //F1-F12
    {
        keyValue.Append(e.KeyCode);
    }
    else if ((e.KeyValue >= 48 && e.KeyValue <= 57))    //0-9
    {
        keyValue.Append(e.KeyCode.ToString().Substring(1));
    }
    this.ActiveControl.Text = "";
    //设置当前运动控件的文本内容
    this.ActiveControl.Text = keyValue.ToString();
}

private void keyUp(object sender, KeyEventArgs e)
{
    string str = this.ActiveControl.Text.TrimEnd();
    int len = str.Length;
    if (len >= 1 && str.Substring(str.Length - 1) == "+")
    {
        this.ActiveControl.Text = "";
    }
}
PHP实例

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    keyDown(sender, e);
}

private void textBox1_KeyUp(object sender, KeyEventArgs e)
{
    keyUp(sender, e);
}
