/// <summary>
    /// 异常类型
    /// </summary>
    public enum FaultCode
    {
        Client = 0,
        Server = 1
    }/// <summary>
    /// 封装异常为SoapException
    /// </summary>
    /// <param name="uri">引发异常的方法uri</param>
    /// <param name="errorMessage">错误信息</param>
    /// <param name="errorNumber">错误号</param>
    /// <param name="errorSource">错误源</param>
    /// <param name="code">异常类型</param>
    /// <returns>封装后的SoapException</returns>
    public SoapException RaiseException(
                                            string uri,
                                            string errorMessage,
                                            string errorNumber,
                                            string errorSource,
                                            FaultCode code
                                        )
    {
        //初始化限定名
        XmlQualifiedName faultCodeLocation = null;//异常类型代码转换
        switch (code)
        {
            case FaultCode.Client:
                faultCodeLocation = SoapException.ClientFaultCode;
                break;
            case FaultCode.Server:
                faultCodeLocation = SoapException.ServerFaultCode;
                break;
        }//构建异常信息结构体
        string strXmlOut = @"<detail>"
                         + "<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);//返回SoapException
        return soapEx;
    }

二、（服务端）WebMethod的异常处理中调用此方法。例如：

    /// <summary>
    /// 根据ID读取人员信息
    /// </summary>
    /// <returns>人员信息类</returns>
    [WebMethod(Description = "根据ID读取人员信息")]
    public PersonInfo WSReadPersonByID(int ID)
    {
        try
        {
            PersonMethod personMethod = new PersonMethod();
            return personMethod.ReadPersonByID(ID);
        }
        catch (System.Exception ex)
        {
            throw RaiseException(
                                    "WSReadPersonByID",
                                    ex.Message,
                                    "1000",
                                    ex.Source,
                                    FaultCode.Server
                                );
        }
    }

三、（客户端）建立SoapException的信息解析类

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Xml;
using System.Web.Services.Protocols;/// <summary>
/// SoapException 信息解析类
/// </summary>
public class SoapExceptionInfo
{
    /// <summary>
    /// 错误号
    /// </summary>
    public string ErrorNumber = string.Empty;
    /// <summary>
    /// 错误信息
    /// </summary>
    public string ErrorMessage = string.Empty;
    /// <summary>
    /// 错误源
    /// </summary>
    public string ErrorSource = string.Empty;/// <summary>
    /// SoapExceptionInfo构造方法
    /// </summary>
    public SoapExceptionInfo()
    {

    }

四、（客户端）使用WebMethod时，使用 SoapException的信息解析类方法

    public PersonInfo ReadByID(int id)
    {
        try
        {
            WSDemoService ws = new WSDemoService();
            ws.Credentials = System.Net.CredentialCache.DefaultCredentials;
            return ws.WSReadPersonByID(id);
        }
        catch (SoapException soapEx)
        {
            SoapExceptionInfo soapExInfo = new SoapExceptionInfo(soapEx);throw new System.Exception(soapExInfo.ErrorMessage);
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
