Featrue的开发与部署以前没做过，需要的时候做了一次感觉不是很难，下面就是一个简单的Feature部署EventHandler来控制列表里的一列在添加和修改时保持唯一。
①先建立类库写Feature其代码如下；
Code
1
using System;
2using System.Collections.Generic;
3using System.Linq;
4using System.Text;
5
6using Microsoft.SharePoint;
7
8namespace BSpaceFeature
9
{
10
public class BSpaceFT:SPFeatureReceiver
11
{
12 public override void FeatureActivated(SPFeatureReceiverProperties properties)
13 {
14 SPWeb web = (SPWeb)properties.Feature.Parent;
15 web.AllowUnsafeUpdates = true;
16 SPList list=web .Lists ["客户管理"];
17 string assembly = "BSpaceEventHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken=4051e4af7309362c";
18 string className = "BSpaceEventHandler.BSpaceEHD";
19 list.EventReceivers.Add(SPEventReceiverType.ItemAdding, assembly, className);
20 list.EventReceivers.Add(SPEventReceiverType.ItemUpdating, assembly, className);
21
}
22 public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
23 {
24 }
25 public override void FeatureInstalled(SPFeatureReceiverProperties properties)
26 {
27 }
28 public override void FeatureUninstalling(SPFeatureReceiverProperties properties)
29 {
30 }
31 }
32
}② 在同一解决方案下面建立类库 来写EventHandler其代码如下；
Code
1using System;
2using System.Collections.Generic;
3using System.Linq;
4using System.Text;
5
6using Microsoft.SharePoint;
7
8namespace BSpaceEventHandler
9{
10 public class BSpaceEHD:SPItemEventReceiver
11 {
12 public override void ItemAdding(SPItemEventProperties properties)
13 {
14 SPWeb web = properties.OpenWeb();
15 SPList list = web.Lists["客户管理"];
16 SPListItemCollection lists = list.Items;
17 string content = "";
18 using (SPWeb web1 = (properties.OpenWeb()) as SPWeb)
19 {
20 SPList List = web1.Lists[properties.ListTitle] as SPList;
21 string sNameTitle = List.Fields["公司名称"].InternalName;
22 content = properties.AfterProperties[sNameTitle].ToString();
23 }
24 string str = "";
25 foreach (SPListItem splist in lists)
26 {
27 if (content.Equals(splist["公司名称"].ToString()))
28 {
29 str = splist["公司名称"].ToString();
30 properties.Cancel = true;
31 properties.ErrorMessage = "公司名称：" + str + "已经存在，您不能添加！请联系管理员！";
32 break;
33 }
34 }
35 }
36 public override void ItemUpdating(SPItemEventProperties properties)
37 {
38 SPWeb web = properties.OpenWeb();
39 SPList list = web.Lists["客户管理"];
40 SPListItemCollection lists = list.Items;
41 SPListItem item = properties.ListItem;
42 string content = "";
43 string strId = item["ID"].ToString();
44 using (SPWeb web1 = (properties.OpenWeb()) as SPWeb)
45 {
46 SPList list1 = web1.Lists[properties.ListTitle] as SPList;
47 string sNameTitle = list1.Fields["公司名称"].InternalName;
48 content = properties.AfterProperties[sNameTitle].ToString();
49 }
50 foreach (SPListItem splist in lists)
51 {
52 if (content.Equals(splist["公司名称"].ToString()))
53 {
54 if (!(strId.Equals(splist["ID"].ToString())))
55 properties.Cancel = true;
56 properties.ErrorMessage = "公司名称：" + splist["公司名称"].ToString() + "已经存在！请联系管理员！";
57 }
58 }
59 }
60 }
61}
③在Feature类库中建立Feature文件夹，在Feature文件夹下建立Feature.xml文件，如下；
Feature.xml
1<?xml version="1.0" encoding="utf-8" ?>
2<Feature xmlns="http://schemas.microsoft.com/sharepoint/"
3 Id="27E28022-CBA3-470d-86BB-AC70E0F83B6A"
4 Title="客户管理"
5 Description="use Feature run EventHandler控制公司名称唯一"
6 Hidden="False"
7 Scope="Web"
8 ReceiverClass="BSpaceFeature.BSpaceFT"
9 ReceiverAssembly="BSpaceFeature, Version=1.0.0.0, Culture=neutral, PublicKeyToken=d7b283ecb74bbf80">
10</Feature>
④将Feature文件夹(其中包含feature.xml文件）拷贝到C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES文件夹下；
⑤在“开始”->运行 cmd 以后输入 cd C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN之后会进入BIN目录下然后在输入STSADM -o InstallFeature -filename Feature\Feature.xml -force来部署Fatrure
⑥在将写的Feature类生成的BSpaceFeature.dll和EventHandler类生成的BSpaceEventHandler.dll拖到GAC里面；
⑦重启iis即iisreset
⑧Feature部署完毕，在网站设置里的网站功能里面就会出现您所部署的Feature，一激活就OK了~！
注意：如果要卸载Feature只需要在⑤步里STSADM -o unInstallFeature -filename Feature\Feature.xml -force就搞定了~！去爽吧~！
