在使用開源項目?SENPARC.WEIXIN SDK 調用微信支付接口的時候出現了WeixinPayInfoCollection尚未注冊Mch，這個問題。

?

最后地解決方案是：

我這個傻逼忘了在全局Global初始化TenPayV3InfoCollection

只要在Global 添加以下代碼

//提供微信支付信息
var tenPayV3_MchId = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_MchId"];
var tenPayV3_Key = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_Key"];
var tenPayV3_AppId = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_AppId"];
var tenPayV3_AppSecret = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_AppSecret"];
var tenPayV3_TenpayNotify = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_TenpayNotify"];

var tenPayV3Info = new TenPayV3Info(tenPayV3_AppId, tenPayV3_AppSecret, tenPayV3_MchId, tenPayV3_Key,
tenPayV3_TenpayNotify);
TenPayV3InfoCollection.Register(tenPayV3Info);

?

代碼示例：

private static TenPayV3Info _tenPayV3Info;/// <summary>/// v3 微信 支付模式屬性/// </summary>public static TenPayV3Info TenPayV3Info{get{if (_tenPayV3Info == null){_tenPayV3Info =TenPayV3InfoCollection.Data[System.Configuration.ConfigurationManager.AppSettings["TenPayV3_MchId"]];}return _tenPayV3Info;}} protected void Application_Start(object sender, EventArgs e){RegisterWeixinPay();}//提供微信支付信息var tenPayV3_MchId = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_MchId"];var tenPayV3_Key = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_Key"];var tenPayV3_AppId = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_AppId"];var tenPayV3_AppSecret = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_AppSecret"];var tenPayV3_TenpayNotify = System.Configuration.ConfigurationManager.AppSettings["TenPayV3_TenpayNotify"];var tenPayV3Info = new TenPayV3Info(tenPayV3_AppId, tenPayV3_AppSecret, tenPayV3_MchId, tenPayV3_Key,tenPayV3_TenpayNotify);TenPayV3InfoCollection.Register(tenPayV3Info);

webconfig 配置

<!-- 微信支付V3 --><add key="TenPayV3_MchId" value="TenPayV3_MchId"/><add key="TenPayV3_Key" value="TenPayV3_Key"/><add key="TenPayV3_AppId" value="TenPayV3_AppId"/><add key="TenPayV3_AppSecret" value="TenPayV3_AppSecret"/><add key="TenPayV3_TenpayNotify" value="TenPayV3_TenpayNotify"/>
