: WEB Infopath 调用sharepooint自开放web service有关问题

紧急求助: WEB Infopath 调用sharepooint自开放web service问题
我在sharepoint 2013 server中(但继续用sharepoint 2010模式)自定义开放了一个webservice, 里面有两个简单演示webmethod, 

        [WebMethod]
        public string TestString(string inputstring)
        {
            return inputstring + " -- get it";
        }

        public string GetSiteListCount()
        {
            var web = SPContext.Current.Web;
            return web.Title;
        }

该webservice 发布到我的sharepoint server上，deploy 路径是 {SharePointRoot}\Template\Layouts\WebServiceDemo\，我再创建一个 console 程序测试引用该webservice（引用路劲是 http://mysharepoint/_layouts/WebServiceDemo/MyCustomWebService.asmx
都能正常使用这两个 WebMethod(上面都是在该服务器上测试)；

我的目的是要在web infopath form上应用， 在infopath vsta中， 仿照console的方式引用及调用它们， 把infopath form 发布到服务器上后测试， 第一个webmethod能正常调用，而第二个则在infopath 开启时出错； 我也怀疑是是否是权限问题， 把调用时用的认证
System.Net.CredentialCache.DefaultCredentials 更改为 
new NetworkCredential("domain\administrator", "password")还是不行

请各路大侠协助，谢谢！
