推荐答案
看看这个
您需要订阅"KeyDown"事件.这是一个示例:
Hi,
you need to subscribe to the "KeyDown" event. Here is an example:
private void Form1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.F && e.Modifiers == Keys.Alt) { //Show the form } }
用于Windows应用程序:
for windows Application:
private void Form1_KeyDown(object sender, KeyEventArgs e) { if (e.Alt & e.KeyCode.ToString() == "F") { Form2 op = new Form2(); op.Show(); } }
适用于Web应用程序:
for Web Application:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default7.aspx.cs" Inherits="Default7" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> <script type="text/javascript"> document.attachEvent('onkeyup', KeysShortcut); // Now we need to implement the KeysShortcut function KeysShortcut () { if (event.keyCode == 17) // 17 keycode is for Left control key { document.getElementById('<%= button1.ClientID %>').click(); } } </script> </head> <body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="a" runat="server"></asp:ScriptManager> </div> <div id="target" style="background-color: gray">This is a simple div</div> <asp:Button ID="button1" runat="server" onclick="Button1_Click" /> </form> </body> </html>
protected void Button1_Click(object sender, EventArgs e) { Response.Redirect("About.aspx", false); }
