base64string 的字符串路径
String path to base64string
我在使用特定编码器生成 base64 字符串时遇到问题。
我有一个生成此 base64 字符串的应用程序

到 base64string 但我得到这个

我该怎么做?
这是我的代码,它给出了错误的结果
var bytes= Encoding.ASCII.GetBytes(msg);
return Convert.ToBase64String(bytes);
这里的问题是您使用的文本编码。
您发布的第一个 Base64 字符串是使用带有 nul 终止符字节对的 Unicode 编码的。尾随的 'AAAAA==' 在这里是一个致命的赠品。您可以通过检查字节数组自己看到它:
var originalB64 = "RQA6AFwAUAByAG8AagBlAGMAdABzAFwAWQBvAHUAdAB1AGIAZQAuAE0AYQBuAGEAZwBlAHIAXABZAG8AdQB0AHUAYgBlAC4ATQBhAG4AYQBnAGUAcgAuAE0AbwBkAGUAbABzAC4AQwBvAG4AdABhAGkAbgBlAHIAXABvAGIAagBcAFIAZQBsAGUAYQBzAGUAXABuAGUAdABzAHQAYQBuAGQAYQByAGQAMgAuADAAXABZAG8AdQB0AHUAYgBlAC4ATQBhAG4AYQBnAGUAcgAuAE0AbwBkAGUAbABzAC4AQwBvAG4AdABhAGkAbgBlAHIALgBkAGwAbAAAAA==";
var bytes = Convert.FromBase64String(originalB64);
将其转换为字符串将为您提供一个 125 个字符长的以 null 结尾的字符串,最后一个字符为 nul。
给定一个不以 nul 结尾的路径,您可以按如下方式重现该字符串:
string path = @"E:\Projects\Youtube.Manager\Youtube.Manager.Models.Container\obj\Release\netstandard2.0\Youtube.Manager.Models.Container.dll";
string newB64 = Convert.ToBase64String(Encoding.Unicode.GetBytes(path + "[=11=]"));
这与我测试中的原始 Base64 字符串完全匹配。
