我正在用C#制作一个Enigma Simulator应用程序。除此之外,我正在尝试制作它的灯板,它基本上是一个键盘,用于点亮反射器返回的字母。现在,我的想法是添加26个带有黄色字母图像的图片框,并在每个图片框的顶部添加26个带有灰色图像字母的其他图片框。
如果用户输入0个字母,则灰色的是可见的。当用户键入一个字母时,它将对其进行解码并根据其设置返回另一个字母,并且该字母应在键盘中打开(字母的黄色图像),然后在下一个字母到达时关闭(灰色图像)。 / p>
以下代码是显示我是如何尝试这样做的部分,但我无法弄清楚如何让它们一个接一个地继续下去。如何实现这一效果的任何帮助或建议都会受到欢迎。
StringBuilder ciphertext = new StringBuilder(txtCiphertext.Text);
int i = 0;
while (i < ciphertext.Length)

您可以在输入KeyPress
事件时验证用户输入。当用户按下某个键时,会引发此事件,并且函数会处理该事件,并执行此函数内的代码。您也可以使用switch
代替多个if
语句。
首先创建处理函数:
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
switch (e.KeyChar)
{
case 'A':
Aoff.Visible = false;
Aon.Visible = true;
break;
case 'B':
Boff.Visible = false;
Bon.Visible = true;
break;
...
}
}
然后你需要将函数与TextBox
。
如果您这样做,当用户按下TextBox
处的按键时,此功能将被执行,它将满足您的需要。

这不是一个完整的解决方案,我只是说出正确的话语。
您可以使用文本框的keyPress事件来捕获用户键入时按下的键。
我们需要一个字典来存储pictureboxe,灰色img和黄色img,char类型的键值是用户要在文本框中键入的字符
所以我们要这样声明:
Dictionary<char, Tuple<PictureBox, string, string>> List = new
Dictionary<char, Tuple<PictureBox, string, string>>();
然后当表单加载时,你从他们的目录中读取imges并填充列表,同时读取我们在表单中的所有pictureBox,并将它们添加到Dictionary中。
我使用了一个groupBox,将PictureBox控件组合在一起,使其循环。
我会假设图片是根据密钥命名的。
private void Form9_Load(object sender, EventArgs e)
{
//Reading both yellow and grey Imgs
string[] grey = Directory.GetFiles(@"C:\greyImgs");
string[] yellow = Directory.GetFiles(@"C:\yellowImgs");
//looping thought the controls in the groupbox which are PictureBoxs
for (int i = 0; i < groupBox1.Controls.Count; i++)
{
// Casting the controls as PictureBox
PictureBox pic = groupBox1.Controls[i] as PictureBox;
// Adding the grey imgs to PictureBoxx
pic.ImageLocation = grey[i];
// Populating the Dictionary
List.Add(Path.GetFileNameWithoutExtension(grey[i])[0], new Tuple<PictureBox, string, string>(pic, grey[i], yellow[i]));
}
}
现在我们之后,我们将一个文本框添加到表单中,然后右键单击它,然后单击向下滚动灯泡图标,直到看到KeyPress双击它。现在为keypress创建了事件处理程序。
所以你把这段代码:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
// e.keychar returns the key that the user pressed
// So we Don't want the user to press a key we don't have so we perform a check
if (List.ContainsKey(e.KeyChar))
{
// Here we get the first item of the tuple which is the picturebox
// and we assign the yellow img being the third item in the tuple.
List[e.KeyChar].Item1.ImageLocation = List[e.KeyChar].Item3;
}
}
希望这有效。
