用C＃编码字符

Question

I'm studying alone from a book. In the book it is said that I can use all symbols that are in the Unicode table (although it is not explained very well). But somehow I can't do it. Here is the code that I test:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace HelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.OutputEncoding = System.Text.Encoding.UTF8;
            char a = '\u2605';
            Console.WriteLine(a);
        }
    }
}

The code should print a star, but the output is

" E"

Can you tell me how I can use any symbol from the table with no problems?

Answer 1

It is Unicode encoding you are looking for:

Console.OutputEncoding = System.Text.Encoding.Unicode;

As mentioned, it will only work if the console supports Unicode. Also, the font used also needs to support the Unicode characters in order to display them. For instance, Lucida Console does not support U+2605 , but it does support other characters .

Console.OutputEncoding = System.Text.Encoding.Unicode;
char a = '\u2191';
Console.WriteLine(a);

The above code will print an upwards arrow in my console using either Consolas , Lucida Console or Raster Fonts .

我很确定您需要先将char转换为字符串，然后尝试

Console.WriteLine(a.ToString());
