c# - 将键与 Windows 窗体上的按钮相关联

Question

我必须在 C# 上编写一个方法，将某个键(来自键盘)与特定按钮相关联。例如，如果我按下 A，我在表单应用程序上创建的按钮应该看起来像是被按下了。

Answer 1

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        this.KeyPreview = true;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        System.Windows.Forms.MessageBox.Show("Ctrl-F was Pressed.");
    }
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if (keyData == (Keys.Control | Keys.F))
        {
            button1.PerformClick();
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }
}

注意:要模拟点击动画，将Click事件做成这样:

    private void button1_Click(object sender, EventArgs e)
    {
        button1.FlatStyle = FlatStyle.Flat;
        System.Windows.Forms.MessageBox.Show("foo");
        button1.FlatStyle = FlatStyle.Standard;
    }

它并不完美，但它确实有效。
