OK，不多说了，看一下Solution的截图
基本上一看就明白了，控制器调用Biz层，Biz层调用DAL层，DAL层进行数据的CURD。Utility是一些公用的类库。ok，为什么程序集的命名都是以Bruce开头呢，因为我在公司的英文名叫这个。废话不多说，我们先看一下页面
我们引入了BootStrap，主要是为了页面布局。在Views中Partial下面放的都是部分页。
我们先看一下运行效果，今天主要是讲页面初始化部分。
其实查询条件就是婚否，出生日期，姓名的模糊查询。我们先看一下页面Index.cshtml的代码

我们使用html5+BootStrap布局，这里用到了BootStrap的网格系统，将浏览器平分为12份，即12列，很容易构造出响应式布局系统。那么什么是BootStrap的网格系统，看如下的解释
OK，我们怎么看是否是响应式的布局呢，我们打开谷歌浏览器，现将浏览器缩小到一定程度。
看到了吧，即使设备浏览器这么小，我们还是能用。那我们在手机模拟器中测试一下，打开谷歌浏览器，按F12，点击手机模拟器样的东西，然后Device选择iphone6。
我们看到iphone6下面的效果是这样的。说到这里我最近很讨厌两个广告，一个是“这个是iphone6，这个是iphone6 plus，它们都有一个叫健康的东西.....但是好吃啊”，还有一个是“当牛魔王变成一个饺子，我愿意变成一双筷子”。看到这两个广告，我想砸电视。
那为什么不同的设备不同的浏览器都是可以正常浏览的呢，原因就在于这段代码
<meta name="viewport" content="width=device-width;initial-scale=1" />

这段代码的意思是网页宽度默认等于屏幕宽度，缩放比例默认为1(网页初始比例占屏幕的100%)。
ok，我们接下来看head部分css和js的引用，这里有个新东西叫Bundle，用来打包压缩js或者css的。通过它打包压缩的js或者css客户端只需要下载一次包即可，而且可以在客户端缓存起来，当检测到有更新时，才会重新下载。
下面是Bundle.cs的代码
using System.Web;
using System.Web.Optimization;
namespace Brue.GRLC.Web
{
public class BundleConfig
{
// 有关 Bundling 的详细信息，请访问 http://go.microsoft.com/fwlink/?LinkId=254725
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/BootStrap").Include(
"~/Scripts/jquery-1.11.1.js","~/BootStrap/js/bootstrap.js"));
bundles.Add(new ScriptBundle("~/bundles/Scripts").Include("~/Js/Index.js"));
bundles.Add(new StyleBundle("~/css").Include("~/BootStrap/css/bootstrap-theme.css"
, "~/BootStrap/css/bootstrap.css"));
}
}
}

注意，在这里引用js的时候不要引用压缩过的js，比如xxx.min.js。当Bundle在遇到这种js命名文件的时候，直接就忽略掉了。那么我们在Head中只需要使用如下代码来引用即可。
@Scripts.Render("~/bundles/BootStrap")
@Scripts.Render("~/bundles/Scripts")

OK，在这我碰到一个问题，就是我的css通过这种方式引用，始终提示Index out of range。如果哪位大牛知道原因的话麻烦留个言，谢谢!
OK，我们接下来看一下控制器代码，页面刚进来，会走Home/Index。
public ActionResult Index()
{
List<object> marriedList = GRLCBiz.GetInstance().GetMarriedList();
SelectList selectList = new SelectList(marriedList, "MarriedID", "DisplayContent", "-1");
ViewBag.MarriedList = selectList;
DataResponse<UserDBEntity> dataResponse = GRLCBiz.GetInstance().GetUserInfoEntityList();
UserInfoViewModel userInfoViewModel = new UserInfoViewModel();
userInfoViewModel.DataResponse = dataResponse;
userInfoViewModel.DataResponse.PageIndex = ConstValues.CONN_DefaultPageIndex;
userInfoViewModel.DataResponse.PageSize = ConstValues.CONN_DefaultPageSize;
userInfoViewModel.DataResponse.StartPageIndex = 1;
return View(userInfoViewModel);

首先我们构造了一个SelectList用于下拉列表，Biz层的代码很简单
public dynamic GetMarriedList()
{
IList<object> marriedList = new List<object>();
marriedList.Add(new { MarriedID = -1, DisplayContent = "No Selection" });
marriedList.Add(new { MarriedID = 0, DisplayContent = "Married" });
marriedList.Add(new { MarriedID = 1, DisplayContent = "UnMarried" });
return marriedList;
}

- 6.
- 7.
- 8.
- 9.
用匿名类去构造一个List。接下来就是DataReponse的获取，Biz层的代码如下
public DataResponse<UserDBEntity> GetUserInfoEntityList(UserInfoRequest request = null)
{
if(request==null)
{
request = new UserInfoRequest();
request.PageIndex = ConstValues.CONN_DefaultPageIndex;
request.PageSize = ConstValues.CONN_DefaultPageSize;
}
int totalCount=0;
List<UserDBEntity> userDBEntityList = GRLCDAL.GetInstance().GetUserInfoEntityList(request, out totalCount);
DataResponse<UserDBEntity> dataResponse = new DataResponse<UserDBEntity>();
dataResponse.DataList = userDBEntityList;
dataResponse.TotalCount = totalCount;
return dataResponse;
}

没什么可说的，ConstValues类中是一些静态只读属性
public class ConstValues
{
public static readonly string CON_DBConnection = ConfigurationManager.ConnectionStrings["DB_ConnectionStr"].ToString();
public static readonly string CON_DbScriptXmlFolder = ConfigurationManager.AppSettings["DbScriptXmlFolder"];
public static readonly int CONN_DefaultPageSize = int.Parse(ConfigurationManager.AppSettings["DefaultPageSize"]);
public static readonly int CONN_DefaultPageIndex = 1;
public static readonly int CONN_PagerDisplayCount = int.Parse(ConfigurationManager.AppSettings["PagerDisplayCount"]);
}

看一下DAL层。
public List<UserDBEntity> GetUserInfoEntityList(UserInfoRequest request, out int totalCount)
{
totalCount = 0;
string sqlScript = string.Empty;
try
{
sqlScript = DBScriptManager.GetScript(this.GetType(), "GetUserInfo");
SqlParameter[] sqlParameters =
{
new SqlParameter("@IsMarried",SqlDbType.Char,1),
new SqlParameter("@StartDate",SqlDbType.DateTime),
new SqlParameter("@EndDate",SqlDbType.DateTime),
new SqlParameter("@UserName",SqlDbType.NVarChar,20),
new SqlParameter("@PageIndex",SqlDbType.Int),
new SqlParameter("@PageSize",SqlDbType.Int),
new SqlParameter("@TotalCount",SqlDbType.Int)
};
sqlParameters[0].Value = request.IsMarried;
sqlParameters[1].Value = request.StartDate;
sqlParameters[2].Value = request.EndDate;
sqlParameters[3].Value = request.UserName;
sqlParameters[4].Value = request.PageIndex;
sqlParameters[5].Value = request.PageSize;
sqlParameters[6].Direction = ParameterDirection.Output;
DataSet ds = SqlHelper.ExecuteDataset(ConstValues.CON_DBConnection, CommandType.Text, sqlScript, sqlParameters);
if (ds != null && ds.Tables.Count > 0)
{
totalCount = Convert.ToInt32(sqlParameters[6].Value);
return ds.Tables[0].ToEntityList<UserDBEntity>();
}
return new List<UserDBEntity>();
}
catch (Exception ex)
{
LogHelper.WriteExceptionLog(MethodBase.GetCurrentMethod(), ex);
return null;
}

OK，我们看一下这个GetUserInfo脚本，在Bruce.GRLC.DbScriptXml程序集下。
<?xml version="1.0" encoding="utf-8" ?>
<Scripts>
<Script Key="GetUserInfo">
<![CDATA[
DECLARE @UserTempTable TABLE

脚本很简单，就是传入参数查分页数据。
在DAL层我们将DataTable通过ToEntityList转化为了实体List，在Utility中我们定义了一个扩展用来转化。
public static class DataTableToEntityExtension
{
public static List<T> ToEntityList<T>(this DataTable dt) where T : class,new()
{
List<T> entityList = new List<T>();
Type entityType = typeof(T);
PropertyInfo[] propertys = entityType.GetProperties();
DataMappingAttribute mappingAttribute = null;
foreach (DataRow dr in dt.Rows)
{
T tEntity = new T();
foreach (PropertyInfo pi in propertys)
{
mappingAttribute = pi.GetCustomAttribute(typeof(DataMappingAttribute)) as DataMappingAttribute;
if (mappingAttribute != null && dt.Columns.Contains(mappingAttribute.mappingName))
{
if (!pi.CanWrite) continue;
object value = dr[mappingAttribute.mappingName];
if (value != DBNull.Value)
pi.SetValue(tEntity, value, null);
}
}
entityList.Add(tEntity);
}
return entityList;
}
}

值那么转化的时候是怎么让DataTable的列和实体匹配起来，你可以将列别名和实体定义成一样的，还有一种你可以使用Attribute。那我们使用后者，因为后者更灵活。
[AttributeUsage(AttributeTargets.Property)]
public class DataMappingAttribute : Attribute
{
public string mappingName;
public DbType dbType;
public DataMappingAttribute()
{ }
public DataMappingAttribute(string mappingName, DbType dbType)
{
this.mappingName = mappingName;
this.dbType = dbType;
}
}

- 9.
- 10.
- 11.
- 12.
- 13.
- 14.
定义好Attribute之后，我们设置其能使用的目标只能是Property。然后我们在实体类里面的属性上加上这个Attribute。
namespace Bruce.GRLC.Model.Entity
{
public class UserDBEntity
{
[DataMapping("UseNo", DbType.AnsiString)]
public string UserID { get; set; }
[DataMapping("Name", DbType.AnsiString)]
public string UserName { get; set; }
[DataMapping("Age", DbType.Int32)]
public int Age { get; set; }
[DataMapping("Married", DbType.String)]
public string Married { get; set; }
}
}

在DataTableToEntityExtension这个扩展中我们得到属性的Attribute去和DataTable的列名去匹配，反射赋值。
OK，拿到数据后，我们在控制器构造viewModel，传递给界面来绑定。我们看一下部分页UserInfoPartial.cshtml的代码
@using Bruce.GRLC.Model.ViewModel;
@model UserInfoViewModel
<table id="tabuserinfo" class="table table-bordered table-hover">
<thead>
<tr style="background-color: #2aabd2;color:white">
<th>帐号</th>
<th>姓名</th>
<th>年龄</th>
<th>婚否</th>
</tr>
</thead>
<tbody>
@if (Model != null && Model.DataResponse != null && Model.DataResponse.DataList != null)
{
foreach (var userEntity in Model.DataResponse.DataList)
{
<tr>
<td>
@userEntity.UserID
</td>
<td>
@userEntity.UserName
</td>
<td>
@userEntity.Age
</td>
<td>
@userEntity.Married
</td>
</tr>
}
}
</tbody>
</table>
<div id="divpagination">
@{Html.RenderPartial("~/Views/Partial/PaginationPartial.cshtml", Model.DataResponse);}

其实也就是一个应用了BoootStrap样式的表格，有边框和鼠标经过的样式。关于BootStrap的样式的使用，请参考BootStrap官网。代码很简单，就是循环遍历，展示数据。
