新人该如何"生存"的问题

Question

新到公司报到,被要求看以前产品的内部代码,不看不知道,一看吓一跳!好深奥啊,代码实现完全跟学校里自己鼓捣的东西天上地下,直接晕了,而且很久恢复不过来,这样的状态正常么?该怎么去适应呢?求各位看官指点迷津啊!这样的状态太难受了!

Answer 3

这代码有什么特别的 ？除了一股脑的写在aspx.cs 再没看到什么

Answer 4

一个一个 复制到MSDN的搜索框中搜索一下 都是基本示例
不清楚的 也可以直接问同事 这么大一堆代码网上怎么解释哦。

Answer 5

<dcpi:Questionaire 
        runat="server" 
        ID="QuestionaireSupplierProfile" 
        TreeViewContainer="PanelPlaceHolderTree"
        QuestionsContainer="PanelPlaceHolderQuestions"
        ButtonsContainer="PanelPlaceHolderButtons"    
        OnQuestionaireCategoryChangedEvent="OnQuestionaireCategoryChangedEvent"  
    />这个没有见过 应该是自己写的控件

Answer 6

就是这个Questionaire 没有看明白 原来是公司自己写的控件 
其他的都没有什么了啊 
很平常的代码啊就是少了注释了 不规范   我们以后开发要注意咯！！！

Answer 7

只看这段：public void Download(object sender, EventArgs e)
    {
        string orgFileName;
        string serverFileName;        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionStringFelix"].ConnectionString);
        SqlCommand cmd = new SqlCommand();
        cmd.Connection = con;
        cmd.CommandText = "select OrgFilename, Filename from dbo.Felix_SupplierDocument where ObjectID = " + ((IButtonControl)sender).CommandArgument;
        con.Open();
        SqlDataReader reader = cmd.ExecuteReader();
        reader.Read();
        orgFileName = (string)reader["OrgFilename"];
        serverFileName =
            ConfigurationManager.AppSettings["UploadPath"]
            + reader["Filename"];
        con.Close();
        Response.ContentType = "APPLICATION/OCTET-STREAM";
        System.String disHeader = "Attachment; Filename=\"" + orgFileName + "\"";
        Response.AppendHeader("Content-Disposition", disHeader);
        System.IO.FileInfo fileToDownload = new System.IO.FileInfo(serverFileName);
        Response.Flush();
        Response.WriteFile(fileToDownload.FullName);
    }
就觉得你写这些代码的那位同事还需要好好提升面向对象设计能力和分析能力，不过楼主不要怕，静下心来，平时多看看一些大师的书，比如重构，敏捷开发，.net大局观，thin in java，多看看优秀的开源代码，比如NHibernate,Enterprise library。不到三个月你就可以超过你这位同事了，真的。所以你不要气馁和退却哦

Answer 8

谢谢所有在这里发言,给予意见建议指正批评的所有朋友,谢谢你们,我开始喜欢CSDN的氛围了,真好!

Answer 9

To：楼主一个小小的建议：你也可以自己试着编写类似的程序或UserControls，一点要去写，看是看不懂的，只有这样才能尽快上手。祝你好运！
