Encoding Char From a String

Question

I have a string

"\u00c7"

I can convert it in code;

char chr = Convert.ToChar("\u00c7"); // value of the chr is **Ç**

but I can't convert like this

I wrore \u00c7 in textbox1

char chr2 = Convert.ToChar(textbox1.Text); //This makes an error - number of character

I'm working on it for hours and can't find any solution.

There is no inbuilt way to do this (escape sequences are only parsed as such at compile time), but its rather easy to parse the string yourself:

static bool TryParseAsChar(this string s, out char c)
{
    if (s != null)
    {
        if (s.Length == 1)
        {
            c = s[0];
            return true;
        }

        if (s.StartsWith("\\u", StringComparison.InvariantCulture) &&
            s.Length == 6)
        {

            var hex = s.Substring(2);

            if (int.TryParse(hex,
                             NumberStyles.AllowHexSpecifier,
                             CultureInfo.InvariantCulture,
                             out var i))
            {
                c = (char)i;
                return true;
            }
        }
    }

    c = default(char);
    return false;
}
