Trying to detect keypress
提问by Adam_MOD
I made a method that detects when a key is pressed, but its not working! Heres my code
我做了一个检测按键被按下的方法，但它不起作用！这是我的代码
void KeyDetect(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.W && firstload == true)
{
MessageBox.Show("Good, now move to that box over to your left");
firstload = false;
}
}
I also tried to make a keyeventhandler but, it sais "cannot assign to key detect because it is a method group"
我也尝试制作一个 keyeventhandler，但是它说“无法分配给键检测，因为它是一个方法组”
public Gwindow()
{
this.KeyDetect += new KeyEventHandler(KeyDetect);
InitializeComponent();
}

Use keypress event like this:
像这样使用按键事件：
private void Form1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyCode == Keys.F1 && e.Alt)
{
//do something
}
}

You are looking for this.KeyPress. See How to Handle Keypress Events on MSDN.
您正在寻找this.KeyPress. 请参阅如何处理 MSDN 上的按键事件。

1) Go to your form's Properties
1) 转到表单的属性
2) Look for the "Misc" section and make sure "KeyPreview" is set to "True"
2) 查找“Misc”部分并确保“KeyPreview”设置为“True”
3) Go to your form's Events
3) 转到表单的事件
4) Look for the "Key" section and double click "KeyDown" to generate a function to handle key down events
4) 找到“Key”部分，双击“KeyDown”，生成处理按键按下事件的函数
Here is some example code:
下面是一些示例代码：
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
Console.WriteLine("You pressed " + e.KeyCode);
if (e.KeyCode == Keys.D0 || e.KeyCode == Keys.NumPad0)
{
//Do Something if the 0 key is pressed (includes Num Pad 0)
}
}
