WeixinPayInfoCollection尚未注册Partner：

Error message

WeixinPayInfoCollection尚未注册Partner：{0}

What it means

TenPayInfoCollection (V2) throws this WeixinException from its string indexer when the requested partner key is not present in the registered TenPayInfo entries. The collection must be pre-populated (via Register) before indexed access; the indexer is a hard-fail lookup, not a dictionary TryGetValue.

Solutions

1. Register the partner before use: new TenPayInfo(...) and TenPayInfoCollection.Register(tenPayInfo) at application startup.
2. Verify the exact partner key used in the indexer matches the registered Partner value (case and whitespace).
3. Check ContainsKey or TryGetValue-style access before indexing in multi-tenant code.
4. Confirm the registration code actually runs in the failing environment (Startup/Global.asax/Program main path).

Example fix

// before
var tenPayInfo = TenPayInfoCollection.Data[partnerId]; // throws if unregistered
// after
if (TenPayInfoCollection.Data.ContainsKey(partnerId))
{
    var tenPayInfo = TenPayInfoCollection.Data[partnerId];
}
else
{
    TenPayInfoCollection.Register(new TenPayInfo(partnerId, appId, appSecret, tenPayPartnerKey, tenPayNotifyUrl));
}

bool partnerRegistered = TenPayInfoCollection.Data.ContainsKey(partnerId);
if (!partnerRegistered) throw new InvalidOperationException($"Partner '{partnerId}' is not registered. Call TenPayInfoCollection.Register at startup.");

bool TryGetTenPayInfo(string partnerId, out TenPayInfo info)
{
    if (TenPayInfoCollection.Data.ContainsKey(partnerId)) { info = TenPayInfoCollection.Data[partnerId]; return true; }
    info = null; return false;
}

try { var info = TenPayInfoCollection.Data[partnerId]; }
catch (WeixinException ex) when (ex.Message.StartsWith("WeixinPayInfoCollection尚未注册Partner"))
{
    log.Error(ex.Message);
    throw new InvalidOperationException("Register the TenPay V2 partner at application startup.", ex);
}

When it happens

Trigger: Accessing tenPayInfoCollection["somePartnerId"] where "somePartnerId" was never registered via TenPayInfoCollection.Register(...) (or the Register call ran in a different app domain / before this lookup).

Common situations: TenPay V2 partner credentials never registered at application startup; key typo or case mismatch between registration and lookup; config loaded in a different process/app pool than the one serving the pay request; multi-tenant code indexing by a partner id that has no V2 entry.
