求助啊，最近在使用ＷＣＦ写服务，客户端需要传递一个接口类型，服务器接收，有哪位高人知道啊！
------解决思路----------------------
传递一个借口类型？ 不是太明白啊。。。。你可以事先定义借口枚举，传枚举就可以了，，可以实现你的功能的

写个json转换类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.Web.Script.Serialization;

public static string ObjectToJSON(object obj)
{
JavaScriptSerializer jss = new JavaScriptSerializer();
try
{
return jss.Serialize(obj);
}
catch (Exception ex)
{
throw new Exception("JSONHelper.ObjectToJSON(): " + ex.Message);

}
调用
[code]
public string DataTableToJSON(DataTable dt)
{
try
{
OrderTrackRouter_IService client = WCFClientProxy<OrderTrackRouter_IService>.GetReusableFaultUnwrappingInstance("OrderTrackRouterService");
using (client as IDisposable)
{
return client.DataTableToJSON(dt);
}
}
catch (Exception ex)
{
return ex.Message.ToString();
}
}
[/code]
------解决思路----------------------
public string DataTableToJSON(DataTable dt)
{
try
{
OrderTrackRouter_IService client = WCFClientProxy<OrderTrackRouter_IService>.GetReusableFaultUnwrappingInstance("OrderTrackRouterService");
using (client as IDisposable)
{
return client.DataTableToJSON(dt) ;
}
}
catch (Exception ex)
{
return ex.Message.ToString();
}
}
web.config配置服务

------解决思路----------------------
可以，但是你要把实现的接口的所有类型都告诉客户端。
查查 KnowType 特性。
