WebService开发中SoapException的用法

这里有两种写法，

第一种, 就是网上流转某大虾写的，用一个String变量任意拼构一个XML字符串，然后用XmlDocument load XML字符串，再将DocumentElement转入到SoapException中构造函数中：

       string strXmlOut = @"<detail>" //注意，一定要用小写的detail节点！
                         + "<Error>"
                         + "<ErrorNumber>" + errorNumber + "</ErrorNumber>"
                         + "<ErrorMessage>" + errorMessage + "</ErrorMessage>"
                         + "<ErrorSource>" + errorSource + "</ErrorSource>"
                         + "</Error>"
                         + "</detail>";

        //装载为Xml文档
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.LoadXml(strXmlOut);

        //实例化SoapException
        SoapException soapEx = new SoapException(errorMessage, faultCodeLocation, uri, xmlDoc.DocumentElement);

        throw soapEx;

第二种，就是MSDN里介绍的正规写法：

XmlDocument doc = new XmlDocument();
            XmlNode node = doc.CreateNode(XmlNodeType.Element,
                SoapException.DetailElementName.Name,
                SoapException.DetailElementName.Namespace);

XmlNode xmlErrorNumber= doc.CreateNode(XmlNodeType.Element, "ErrorNumber", "http://tempuri.org/");
            xmlErrorNumber.InnerText = exceptionInfo.ErrorCode; //exceptionInfo是一个自定义类型 

            node.AppendChild(xmlErrorNumber);

XmlNode xmlErrorMessage= doc.CreateNode(XmlNodeType.Element, "ErrorMessage", "http://tempuri.org/");
            xmlErrorNumber.InnerText = exceptionInfo.StackTrace; 

            SoapException soapEx = new SoapException(exceptionInfo.ErrorMessage, faultCodeLocation, uri, node);

            throw soapEx;
