c#实现邮件功能，我用c#语言实现了邮件发送的代码

这是国外的同行编写的画图板程序，感觉比陈建春的要好些，说实话研究了半天，发现国内的cad水平低不是因为国内的人笨，主要是国外的cad技术不能很快的传递到国人手中，总是参考陈建华等水平有限，工程水平差的书籍造成整体水平低，书中没有详细的流程图，和软件设计思路，而且代码错误连篇。(This is the foreign counterparts of the drawing board to prepare procedures, CHEN Jian-chun than feeling the need to better tell the truth for a long time study and found that low levels of domestic cad because people are not stupid, mainly abroad cad technology should not quickly delivered to the the hands of the people always refer to Chen Jianhua, such as the limited level, engineering level difference caused by the overall level of books low, the lack of a detailed flow chart of the book, and software design, and code errors pack.)

首先通过文件操作，读取文件内容，把字符逐个提取后统计字符频率，建立哈夫曼树和进行哈夫曼编码，当然这是根据ASCII编码来将字符转换为二进制，然后实现前缀编码，然后把编码后的使用二进制流写入相应文件(First through file operations, read the file content, the characters one by one after extracting character frequency statistics, establish a Huffman tree and Huffman encoding, and, of course, this is according to ASCII code to convert characters to the binary, then realize the prefix encoding, and then the encoded using binary stream into the corresponding files )
