c# - Unicode 字符串到二进制字符串和二进制字符串到 unicode c#

Question

我有一个带有一些 unicode 字符的 unicode 文本说，“你好，世界!这一段有一些 unicode 字符。”

我想将此段落转换为二进制字符串，即数据类型为字符串的二进制数字。转换后，我还想将该二进制字符串转换回 unicode 字符串。

如果您只是在寻找一种方法将字符串解码和编码为 byte[] 而不是实际的二进制文件，那么我会使用 System.Text

来自msdn的实际例子:

      string unicodeString = "This string contains the unicode character Pi (\u03a0)";

  // Create two different encodings.
  Encoding ascii = Encoding.ASCII;
  Encoding unicode = Encoding.Unicode;

  // Convert the string into a byte array.
  byte[] unicodeBytes = unicode.GetBytes(unicodeString);

  // Perform the conversion from one encoding to the other.
  byte[] asciiBytes = Encoding.Convert(unicode, ascii, unicodeBytes);

  // Convert the new byte[] into a char[] and then into a string.
  char[] asciiChars = new char[ascii.GetCharCount(asciiBytes, 0, asciiBytes.Length)];
  ascii.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0);
  string asciiString = new string(asciiChars);

  // Display the strings created before and after the conversion.
  Console.WriteLine("Original string: {0}", unicodeString);
  Console.WriteLine("Ascii converted string: {0}", asciiString);

不要忘记
