Getting a few different exceptions related to Base-64 strings in C#. Below are the exceptions along with sample string. I don't know too much about this topic but I believe I did confirm the lengths of the following strings are multiples of 4. I'm hoping these issues are all related but I'm not sure.

推荐答案

当我去看看我用的是脱code中的字符串回应安德烈的问题是什么，我意识到，我一直在做一个假设这是从真正的问题我睁不开眼。

As I went to look at what I was using to decode the string in response to Andrey's question, I realized that I had been making an assumption that was blinding me from the real issue.

该数据串正在通过查询字符串参数传递，我是假设参数作为自定义错误消息我得到的是坏的字符串看到的时候，其实，稍微调试表明，我其实是试图字符串德code有空格。通过查询字符串张贴字符串是造成所有的加号（+）符号来得到德codeD插入空格。我能够从那里解决这个问题。

The data string is being passed through a querystring parameter and I was assuming that parameter as seen in the custom error message I was getting was the bad string when, in fact, a little debugging showed that the string I was actually attempting to decode had whitespaces. Posting the string through the querystring was causing all the plus (+) signs to get decoded into whitespace. I am able to resolve this issue from there.
