除此之外：[抱歉@Kendall Frey :-)]
char a = '?';
string escape = "\u" + ((int)a).ToString("X").PadLeft(4, '0');
采纳答案by Kendall Frey
Here's a function to convert a char to an escape sequence:
这是一个将字符转换为转义序列的函数：
string GetEscapeSequence(char c)
{
return "\u" + ((int)c).ToString("X4");
}
It isn't gonna get much better than a one-liner.
它不会比单线更好。
And no, there's no built-in function as far as I know.
不，据我所知，没有内置功能。

There is no built-in function AFAIK. Here is one pretty silly solution that works. But Kendall Frey provided much better variant.
AFAIK 没有内置函数。这是一个非常愚蠢的解决方案。但是 Kendall Frey 提供了更好的变体。
string GetUnicodeString(string s)
{
StringBuilder sb = new StringBuilder();
foreach (char c in s)
{
sb.Append("\u");
sb.Append(String.Format("{0:x4}", (int)c));
}
return sb.ToString();
}
