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 = "";
??? }
}

{
??? keyDown(sender,e);
}

private void textBox1_KeyUp(object sender,KeyEventArgs e)
