文档管理项目

下面总结项目总用到的知识

1、登录

此次项目是采用xml文件的形式存储管理员密码，进行登录和修改密码操作

<?xml version="1.0" encoding="utf-8"?>
<Users>
  <FirstUser userName="zhangsan" userPwd="111111" />
</Users>

//读取user.xml文件
string path = Server.MapPath("~/Areas/Admin/Xml/user.xml");
XmlDocument document = new XmlDocument();
document.Load(path);
XmlNode rootNode = document.DocumentElement;
XmlNode firstNode = rootNode.FirstChild;
string userName = firstNode.Attributes["userName"].Value.Trim();
string userPwd = firstNode.Attributes["userPwd"].Value.Trim();

使用了YZMHelper产生验证码

YZMHelper y = new YZMHelper();
//创建验证码
y.CreateImage();
//获取验证码文本
TempData["Yzm"] = y.Text;
//将验证码保存到指定路径下
System.Drawing.Bitmap b = y.Image;
b.Save(path, System.Drawing.Imaging.ImageFormat.Png);

2、统计报表

使用的是DotNet.Highcharts报表插件

Highcharts chart = new Highcharts("mychart")
                .SetTitle(new Title() { Text = "每一年项目的总金额" })
                .SetSubtitle(new Subtitle() { Text = "数据来源:项目文档管理系统" })
                .SetSeries(new Series() { Type=DotNet.Highcharts.Enums.ChartTypes.Line,Name = "项目总金额", Data = new DotNet.Highcharts.Helpers.Data(moneyList.ToArray())})
                .SetXAxis(new XAxis() { Categories = yearList.ToArray()})
                .SetYAxis(new YAxis() { })
                .SetCredits(new Credits() { Enabled = false })
                .SetLegend(new Legend() { Layout = DotNet.Highcharts.Enums.Layouts.Vertical, Align = DotNet.Highcharts.Enums.HorizontalAligns.Right, VerticalAlign=DotNet.Highcharts.Enums.VerticalAligns.Top });

@model DotNet.Highcharts.Highcharts@{
    ViewBag.Title = "";
    Layout = "~/Areas/Admin/Views/Shared/_LayoutPage.cshtml";
}

<script src="/Scripts/jquery-1.4.4.js" type="text/javascript"></script>
<script src="/Scripts/highcharts.js" type="text/javascript"></script>

  <div id="container" style="min-width:700px;height:400px">
   @(Model)
  </div>

3、缓存的使用

数据库存在时

首先建立数据库缓存依赖

比如：（直接在cmd下运行）

@echo off
"C:\Program Files\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"
aspnet_regsql -S localhost -E -ed -d ProjectManageDB -et -t TblProjectInfo

然后在web.config中的<system.web> </system.web>中加入如下代码

<caching>
  <sqlCacheDependency>
    <databases>
        <!--connectionStringName：连接数据库的连接字符串，name:数据库名称-->
      <add connectionStringName="ProjectManageDBConnectionString" name="ProjectManageDB" pollTime="2000"/>
    </databases>
  </sqlCacheDependency>
</caching>

接着使用CacheHelper的Add方法添加缓存即可

CacheHelper.Add(key, projectList,"ProjectManageDB","TblProjectInfo");
