1、使用List<T>.ConvertAll方法

public List<string> GetDisallowedUserNames()

{

List<DisallowedUser> list = GetDisallowedUsers();

return list.ConvertAll<string>(new Converter<DisallowedUser, string>(delegate(DisallowedUser u) { return u.UserName; }));

}

[Serializable]

public class DisallowedUser

{

private string userName;

private DateTime createdDate;

/// <summary>

/// 用户名

/// </summary>

public string UserName

{

get { return userName; }

set { userName = value; }

}

/// <summary>

/// 添加时间

/// </summary>

public DateTime CreatedDate

{

get { return createdDate; }

set { createdDate = value; }

}

2、CheckBox全选例子。

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DisallowedUserList.aspx.cs" Inherits="Admin_DisallowedUserList" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

// <![CDATA[

function doSelectThis()

{

var flag = true;

var objs = getCheckBoxs();

for(i=0; i<objs.length; i++)

{

//只要有一项没有选择，则不能设置为全选

if(objs[i].checked == false)

{

flag = false;

break;

}

var obj = document.getElementById('chbSelectAll');

if(flag)

{

obj.checked = true;

}

else

{

obj.checked = false;

}

function doSelectAll()

{

var objs = getCheckBoxs();

for(i=0; i<objs.length; i++)

{

objs[i].checked = isCheckAll() ? true : false;

}

function isCheckAll()

{

var obj = document.getElementById('chbSelectAll');

return obj.checked;

}

function getCheckBoxs()

{

var ids = document.getElementById('<%= hfClientIDs.ClientID %>').value + ']';

var idArray = eval('(' + ids + ')');

var objs = new Array();

for(i=0; i<idArray.length; i++)

{

objs.push(document.getElementById(idArray[i]));

}

return objs;

}

// ]]>

</script>

<body>

<div>

string clientId = ConfigurationManager.AppSettings["ClientId"];

string clientKey = ConfigurationManager.AppSettings["ClientKey"];

return PermissionServices.HavePermission(clientId, clientKey, applicationId, targetId, this.UserName, permissions);

}

3、使用svcutil 生成WCF客户端
打开Visual Studio 2008 Command Prompt
d:
cd temp
svcutil /language:c# /out:NotifyServiceClient.cs /config:app.config http://localhost:8000/Service/NotifyService.svc

4、手工书写WCF客户端

public class CacheNotifiedUserClient : ClientBase<ICacheNotifiedUser>, ICacheNotifiedUser

{

public CacheNotifiedUserClient() : base() { }

public CacheNotifiedUserClient(InstanceContext callbackInstance) : base(callbackInstance) { }

public CacheNotifiedUserClient(string endpointConfigurationName) : base(endpointConfigurationName) { }

public CacheNotifiedUserClient(Binding binding, EndpointAddress remoteAddress) : base(binding, remoteAddress) { }

public CacheNotifiedUserClient(InstanceContext callbackInstance, string endpointConfigurationName) : base(callbackInstance, endpointConfigurationName) { }

public CacheNotifiedUserClient(string endpointConfigurationName, EndpointAddress remoteAddress) : base(endpointConfigurationName, remoteAddress) { }

public CacheNotifiedUserClient(string endpointConfigurationName, string remoteAddress) : base(endpointConfigurationName, remoteAddress) { }

public CacheNotifiedUserClient(InstanceContext callbackInstance, Binding binding, EndpointAddress remoteAddress) : base(callbackInstance, binding, remoteAddress) { }

public CacheNotifiedUserClient(InstanceContext callbackInstance, string endpointConfigurationName, EndpointAddress remoteAddress) : base(callbackInstance, endpointConfigurationName, remoteAddress) { }

public CacheNotifiedUserClient(InstanceContext callbackInstance, string endpointConfigurationName, string remoteAddress) : base(callbackInstance, endpointConfigurationName, remoteAddress) { }

public void Dispose() { this.Close();}

public bool Contains(string userName)

{

return this.Channel.Contains(userName);

}

5、如何方便地自动生成WCF客户端及配置文件。
A、设置VS2008 X86 tools的环境：Call "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86
B、svcutil /language:c# /out:NotifyServiceClient.cs /config:app.config http://localhost:8000/Service/NotifyService.svc
C、写成一个生成后事件
