最近几天遇到一些URL参数明文显示的问题，因为是明文显示，容易让人通过改变参数查看到他没有权限看到内容。
一开始我的做法是自定义了规则，然后原始的那种URL编码。可是URL编译后效果不理想，他无法编译数字，而且编码后的字符串太长。
最后我在网上用了BASE64这种。感觉还可以。摘录下来，做一下备忘，以后还会用到
C# BASE64 解码和编码
string a = "【OK,Let's GO】";
byte[] b = System.Text.Encoding.Default.GetBytes(a);
//转成 Base64 形式的 System.String
a = Convert.ToBase64String(b);
Console.WriteLine(a);
//转回到原来的 System.String。
byte[] c = Convert.FromBase64String(a);
a = System.Text.Encoding.Default.GetString(c);
Console.WriteLine(a);
