这是接收通知页面的代码逻辑，必须要把对通知处理的结果返回给微信。如果微信发送通知后收不到回复，会以每隔30分钟的频率，向通知页面发送8次通知。

protected void Page_Load(object sender, EventArgs e)

{
    string postStr = "";
    /// <summary>  
    /// 微信支付回调   
    /// </summary>  
    /// <param name="xml"></param>  
    if (Request.HttpMethod.ToLower() == "post")
    {
        Stream s = System.Web.HttpContext.Current.Request.InputStream;
        byte[] b = new byte[s.Length];
        s.Read(b, 0, (int)s.Length);
        postStr = Encoding.UTF8.GetString(b);

        if (!string.IsNullOrEmpty(postStr))
        {
            var res = XDocument.Parse(postStr);
            if (res.Element("xml").Element("return_code").Value == "SUCCESS")
            {
                Response.Write(string.Format(@"<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>"));
                Response.End();
            }
            Response.Write(string.Format(@"<xml><return_code><![CDATA[{0}]]></return_code><return_msg><![CDATA[{1}]]></return_msg></xml>", "FAIL", res.Element("xml").Element("return_msg").Value));
        }
    }
}

一定要注意微信配置项，和微信支付2.0不同的地方是要加一个api_token，这个参数从“微信支付商户平台”中配置，首先登陆商户平台，依次打开“账户设置”、“安全设置”、“API安全”，在API密钥中点击“设置密钥”按钮，自定义API密钥。

/// <summary>

public class WxConfig
{
    /// <summary>
    /// 应用ID
    /// </summary>
    public string AppID { get { return (string)System.Configuration.ConfigurationManager.AppSettings["WXAppID"]; } }

    /// <summary>
    /// 应用密钥
    /// </summary>
    public string AppSecret { get { return (string)System.Configuration.ConfigurationManager.AppSettings["WXAppSecret"]; } }

    /// <summary>
    /// API密钥（支付密钥）
    /// </summary>
    public string ApiToken { get { return (string)System.Configuration.ConfigurationManager.AppSettings["WXApiToken"]; } }

    /// <summary>

    public string PartnerId { get { return (string)System.Configuration.ConfigurationManager.AppSettings["PartnerId"]; } }

    /// <summary>

    /// <summary>

    public string ReturnUrl { get { return Convert.ToString(System.Configuration.ConfigurationManager.AppSettings["ReturnUrl"]); } }

    /// <summary>

    public string OpenId { get; set; }

    public string SignType { get; set; }
