个在线聊天
插件
插件参考了MSDN中Duplex WCF服务实现和网上些聊天
基本可以实现用户登录和聊天如果用户不存在就保存聊天数据到数据库等用户下次登陆时候读入
这个是聊天时候
图例:
为什么不使用在客户单添加WCF服务思路方法生成代理类然后进行编首先是生成代理类我没有发现可以实现WCF双向传输思路方法在网上也没有找到所以就参照msdn和些网上代码自己编写代理类进行操作:1: 定义聊天时候传输聊天
数据实体参照服务器端聊天数据实体定义在客户端定义如下实体:[DebuggerStepThroughAttribute
]
[GeneratedCodeAttribute("
.Runtime.Serialization", "3.0.0.0")]
[DataContractAttribute(Name = "ChatMessage", Namespace = "http://schemas.datacontract.org/2004/07/")]
public partial 
ChatMessage : object
{
private 
DataField;
private FromField;
private ToField;
private 
TypeField;
private 
ContentField;
[DataMemberAttribute]
public Data
{
get
{
this.DataField;
}
{
((object.ReferenceEquals(this.DataField, value) != true))
{
this.DataField = value;
}
}
}
[DataMemberAttribute]
public From
{
get
{
this.FromField;
}
{
((object.ReferenceEquals(this.FromField, value) != true))
{
this.FromField = value;
}
}
}
[DataMemberAttribute]
public To
{
get
{
this.ToField;
}
{
((object.ReferenceEquals(this.ToField, value) != true))
{
this.ToField = value;
}
}
}
[DataMemberAttribute]
public Type
{
get
{
this.TypeField;
}
{
((object.ReferenceEquals(this.TypeField, value) != true))
{
this.TypeField = value;
}
}
}
[DataMemberAttribute]
public Content
{
get
{
this.ContentField;
}
{
((object.ReferenceEquals(this.ContentField, value) != true))
{
this.ContentField = value;
}
}
} 这个实体类
定义其实是可以自动生成2:把对WCF服务
访问思路方法单独处理成个对象模式和结构基本和MSDN上那篇文章样: public void Start
{
// Instantiate the binding and the time-outs
PollingDuplexHttpBinding binding = 
PollingDuplexHttpBinding
{
ReceiveTimeout = TimeSpan.FromSeconds(45),
InactivityTimeout = TimeSpan.FromMinutes(1)
};
// Instantiate and open channel factory from binding
IChannelFactory<IDuplexSessionChannel> factory =
binding.BuildChannelFactory<IDuplexSessionChannel>( BindingParameterCollection);
IAsyncResult factoryOpenResult =
factory.BeginOpen( AsyncCallback(OnOpenCompleteFactory), factory);
(factoryOpenResult.CompletedSynchronously)
{
CompleteOpenFactory(factoryOpenResult);
}
}
void _disibledevent= txt;
}
}
}
}接受到区别
信息的后把对应消息显示到区别窗口上免得混杂在起:至此
聊天主要功能完成
