编码字符串和基64 [英] Encoding strings to and from base-64

问题描述

我是从基地-64串试图连接code一些字符串来回我有truble，以获得正确的结果。

 字符串文本= base64string .... //这里我有一个base-64字符串。
字节[] EN codedByte = System.Text.ASCIIEncoding.ASCII.GetBytes（文本）;
字符串base64En codeD = Convert.ToBase64String（EN codedByte）;如果（文字== base64En codeD）//如果新的EN codeD字符串等于其初始值
    返回base64En codeD;
 

我已经试过我的方法可以做到这一点，我似乎并没有得到正确的结果。我与 System.Text.Encoding.Uni code 和 System.Text.Encoding.UTF8 尝试都

这可能是什么问题呢？有没有人有一个妥善的解决办法？

解决方案

 字符串文本= base64string .... //这里我有一个base-64字符串。
字节[] EN codedByte = System.Text.ASCIIEncoding.ASCII.GetBytes（文本）;
字符串base64En codeD = Convert.ToBase64String（EN codedByte）;
 

您是双编码字符串。你开始用一个base64字符串，得到的字节数，然后的连接code一遍的。如果你想比较，您将需要开始与原始字符串。

I'm trying to encode some strings back and forth from base-64 string and I'm having truble to get the right result.

string text = base64string.... //Here I have a base-64 string.
byte[] encodedByte = System.Text.ASCIIEncoding.ASCII.GetBytes(text);
string base64Encoded = Convert.ToBase64String(encodedByte);

if (text == base64Encoded) //If the new encoded string is equal to its original value
    return base64Encoded;

I have tried my ways to do this and I don't seem to get the right result. I have tried both with System.Text.Encoding.Unicode and System.Text.Encoding.UTF8

What could be the problem? Does anyone have a proper solution?

解决方案

string text = base64string.... //Here I have a base-64 string.
byte[] encodedByte = System.Text.ASCIIEncoding.ASCII.GetBytes(text);
string base64Encoded = Convert.ToBase64String(encodedByte);

You are double encoding the string. You begin with a base64 string, get the bytes, and then encode it again. If you want to compare you will need to begin with the original string.
