如何找到与我的alt代码匹配的字符

Question

当我输入 Alt + 1 时，我会回来☺ 我想在代码中使用一些神奇的方法来获取字符串中的☺字符。

这样的事情：

然后在富文本框中应该有：string smiley = AltCodes.GetAltCodeCharacter(1).ToString(); // Display the Smiley richTextBoxHappy.Text = smiley;

Answer 1

您可以使用Unicode Table (Decimal)查找代码，然后像这样使用它：

int i = 9786;
textBoxHappy.Text = ((char)i).ToString();

结果图片：

修改

当然，您可以创建自定义映射，例如某些Dictionary<string, int>（或您想要的任何自定义类型），并向其添加代码{ "smiley", 9786 }，然后使用altCode["smiley"]。

更新

或者使用enum：

enum AltCodes
{
    Smiley = 9786,
    NextSmiley = 9787
}

并使用它：

textBoxHappy.Text = ((char)AltCodes.Smiley).ToString();

您甚至可以创建自定义解码器，然后在wpf TextBox内编写alt代码（通过按住alt并输入数字），单击“Decode”并将代码值设为{ {1}}例如：

int[]

和用法（点击事件或命令）：

private int[] DecodeCharCode(string str) =>
    DecodeCharCode(str.ToArray());


private int[] DecodeCharCode(char[] chars)
{
    int[] result = new int[chars.Length];
    for (int i = 0; i < chars.Length; i++)
    {
        result[i] = (int)chars[i];
    }
    return result;
}

Answer 2

There is a finite number of these.您只需创建Dictionary<int, string>即可存储所有这些内容：

IReadOnlyDictionary<int, string> altCodes = new Dictionary<int, string>() {
    {1, "☺"},
    {2, "\U0000263B"},
    // and so on...
};

并按如下方式访问：

altCodes[1]
