推荐答案

最好的方法是将您的文本转换为 base 64 字符，然后将其存储到数据库中.而从数据库中获取它时使用反之亦然转换.

The best way is to convert your text into base 64 character and then store it to database. And while fetching it from database use vice-versa conversion.

 byte[] byt = System.Text.Encoding.UTF8.GetBytes(strOriginal);
// convert the byte array to a Base64 string
strModified = Convert.ToBase64String(byt);

并由此恢复正常字符串

  byte[] b = Convert.FromBase64String(strModified);
strOriginal = System.Text.Encoding.UTF8.GetString(b);
