问题描述
您好我有一个包含各种字符的流。当我使用StreamWriters将其写入文件（尝试了3个不同的类）时，其中一个有点垂直矩形的字符被写为此字符 。这在c＃中解密时会产生异常。
问题是这些字符是AES加密的结果，我想用C＃解密这个文件。当我在c＃中加密相同的文本时，它不会产生这些问号但会生成矩形..它在java中完全解密。
但是当我在C＃中加密并解密时在JAVA中，它工作得非常好......那就是C＃使矩形和java转换成功加密文档成为纯文本。
请帮忙！
Hi I have a stream that contains all sorts of characters. When I write it to file using StreamWriters (tried 3 different classes) one of the char that is kinda vertical rectangle gets written as this character �. This gives exception while being decrypted in c#
The problem is that these characters are result of AES encryption and I want to decrypt this file in C#. When i encrypt the same text in c# it doesnt make these question marks but makes rectangles.. which gets decrypted in java perfectly.
However when i encrypt in C# and decrypt in JAVA, it works perfectly fine... That is C# makes rectangles and java converts that encrypted document successfully into plain text.
Please help!
