C# Unicode 字符串

Unicode characters string

提问by Marc Andreson

I have the following Stringof characters.

我有以下String字符。

string s = "\u0625\u0647\u0644";

When I print the above sequence, I get:

当我打印上述序列时，我得到：

\u0625\u0647\u062

How can I get the real printable Unicode characters instead of this \uxxxx representation?

Try Regex:

尝试Regex：

String inputString = "\u0625\u0647\u0644";

var stringBuilder = new StringBuilder();
foreach (Match match in Regex.Matches(inputString, @"\u([\dA-Fa-f]{4})"))
{
    stringBuilder.AppendFormat(@"{0}", 
                               (Char)Convert.ToInt32(match.Groups[1].Value));
}

var result = stringBuilder.ToString();

If you really don't control the string, then you need to replace those escape sequences with their values:

如果你真的不控制字符串，那么你需要用它们的值替换这些转义序列：

Regex.Replace(s, @"\u([0-9A-Fa-f]{4})", m => ((char)Convert.ToInt32(m.Groups[1].Value, 16)).ToString());

and hope that you don't have \\escapes in there too.

并希望你\\在那里也没有逃脱。
