C#转换Base64 - > byte []

Question

我有一个 Base64 byte[]数组从流转移,我需要将其转换为正常byte[]如何做到这一点？

Answer 1

您必须使用Convert.FromBase64String将Base64编码string转换为byte[].

Answer 2

这可能会有所帮助

byte[] bytes = System.Convert.FromBase64String(stringInBase64);

Answer 3

尝试

byte[] incomingByteArray = receive...; // This is your Base64-encoded bute[]

byte[] decodedByteArray =Convert.FromBase64String (Encoding.ASCII.GetString (incomingByteArray)); 
// This work because all Base64-encoding is done with pure ASCII characters
