c# - 字符串类型转换 C#

Question

这是我的问题：我有一个字符串，我认为它是二进制的：

zv�Q6��.�����E3r

我想将此字符串转换为可以读取的内容。我如何在 C# 中做到这一点？

Answer 1

byte[] hexbytes = System.Text.Encoding.Unicode.GetBytes();

这为您提供了字符串的十六进制字节，但您必须知道字符串的编码并用它替换“Unicode”。

Answer 2

您可以尝试枚举（测试）所有可用的编码，并找出对合理文本进行编码的编码。不幸的是，当它不是一个绝对的解决方案时：它可能是错误转换导致的信息丢失。

   public static String GetAllEncodings(String value) {
      List<Encoding> encodings = new List<Encoding>();

      // Ordinary code pages
      foreach (EncodingInfo info in Encoding.GetEncodings()) 
        encodings.Add(Encoding.GetEncoding(info.CodePage));

      // Special encodings, that could have no code page
      foreach (PropertyInfo pi in typeof(Encoding).GetProperties(BindingFlags.Static | BindingFlags.Public))
        if (pi.CanRead && pi.PropertyType == typeof(Encoding))
          encodings.Add(pi.GetValue(null) as Encoding);

      foreach (Encoding encoding in encodings) {
        Byte[] data = Encoding.UTF8.GetBytes(value);
        String test = encoding.GetString(data).Replace('\0', '?');

        if (Sb.Length > 0)
          Sb.AppendLine();    

        Sb.Append(encoding.WebName);
        Sb.Append(" (code page = ");
        Sb.Append(encoding.CodePage);
        Sb.Append(")");

        Sb.Append(" -> ");
        Sb.Append(test);
      }

      return Sb.ToString();
    }

    ...


// Test / usage

    String St = "Некий русский текст";      // <- Some Russian Text
    Byte[] d = Encoding.UTF32.GetBytes(St); // <- Was encoded as UTF 32
    St = Encoding.UTF8.GetString(d);        // <- And erroneously read as UTF 8

    // Let's see all the encodings:
    myTextBox.Text = GetAllEncodings(St);

    // In the myTextBox.Text you can find the solution:
    // ....
    // utf-32 (code page = 12000) -> Некий русский текст
    // ....
