又一种XML的解析方法

[Fact(DisplayName="用户名为空")]

        public void Should_UsernameEmpty()

        {

            var paras = new Dictionary<string, string>

            {

                {"action","send"},

                {"userid",userid},

                {"account",""},

                {"password",password},

                {"mobile",mobile},

                {"content",content},

                {"sendtime",sendTime},

                {"extno",extno}

            };

            var rlt = HttpClientHelper.Instance.Post("sms.aspx", paras);

            Assert.False(string.IsNullOrEmpty(rlt));

            var root = XElement.Parse(rlt).XPathSelectElement("/");

            var msg = root.XPathSelectElement("message").Value;

            Assert.True(msg.Equals("用户名为空"));

        }

注意的是必须引用using System.Xml.Linq; using System.Xml.XPath;要不然是不能用的哦
