Javascript atob（str）在c＃中等效 [英] Javascript atob(str) equivilent in c#
本文介绍了Javascript atob（str）在c＃中等效的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我这样做了：
byte[] data = Convert.FromBase64String(str);
string decodedString = Encoding.UTF8.GetString(data);
Console.WriteLine(decodedString);
但得到未处理的异常：System.FormatException：Base的长度无效 - 64个char数组或字符串。
在javascript中使用 atob（str）给我正确解码的str。
In javascript using atob(str) gives me the right decoded str.
javascript控制台：
javascript console:

int mod4 = str.Length % 4;
if (mod4 > 0)
{
str += new string('=', 4 - mod4);
}
