本篇随笔主要是关于Flex与asp.net的WebService通讯，其中利用了SoapHeader。(如果你对SoapHeader不了解，可以参考WebService开发(一) 如何使用Soap头)。由此可见WebService在跨平台方面的优势。
　　ASP.NET的WebService代码
以下是引用片段：

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
[WebService(Namespace = "http://davidfan.cnblogs.com")]//名称空间应该和Flex中定义相同
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
public ValidateSoapHeader header;
[WebMethod]
[SoapHeader("header")]
public string HelloWorld()
{
      if (header == null)
      {
         return "请提供验证信息.";
      }
      else
      {
         if (header.Name == "admin" && header.Password == "admin")
         {
            if (header.ExDate < DateTime.Now)
            {
                  return "帐号过期";
            }
            else
            {
                  return "验证成功";
            }
         }
         else
         {
            return "用户名或密码错误";
         }
      }
}
}
/**//// <summary>
/// 继承自SoapHeader的自定义类
/// </summary>
public class ValidateSoapHeader : System.Web.Services.Protocols.SoapHeader
{
public ValidateSoapHeader()
{
}
public ValidateSoapHeader(string name, string password, DateTime dt)
{
      this.name = name;
      this.password = password;
      this.exDate = dt;
}
private string name;
public string Name
{
      get { return name; }
      set { name = value; }
}
private string password;
public string Password

{
      get { return password; }
      set { password = value; }
}
private DateTime exDate;
public DateTime ExDate
{
      get { return exDate; }
      set { exDate = value; }
}
