Error message

必须指定待删除的分账接收方

What it means

TenpayV3ProfitShareingRemoveReceiverRequestData's constructor requires a Receiver object identifying the profit-sharing receiver to delete. Passing null throws an ArgumentNullException with this message.

Solutions

1. Build a Receiver with at least Type and Account set, then pass it to the constructor.
2. Check argument order/positions — a shifted null argument may be landing on the receiver parameter.
3. Skip the remove call when the receiver record doesn't exist instead of passing null.

Example fix

// before
var data = new TenpayV3ProfitShareingRemoveReceiverRequestData(key, appid, mchid, null, version);
// after
var receiver = new Receiver { Type = "MERCHANT_ID", Account = "190001001" };
var data = new TenpayV3ProfitShareingRemoveReceiverRequestData(key, appid, mchid, receiver, version);

// C#
if (receiver is null)
    throw new InvalidOperationException("Receiver must be provided to remove a profit-sharing receiver");

bool CanRemove(Receiver r) => r is not null && !string.IsNullOrWhiteSpace(r.Account);

try { var data = new TenpayV3ProfitShareingRemoveReceiverRequestData(key, appid, mchid, receiver, version); }
catch (ArgumentNullException ex) when (ex.Message.Contains("分账接收方")) { log.LogWarning("RemoveReceiver skipped: receiver was null"); }

When it happens

Trigger: new TenpayV3ProfitShareingRemoveReceiverRequestData(...) with receiver = null when removing a 分账接收方.

Common situations: Trying to remove a receiver whose record was already deleted locally, so the lookup returned null, or misordering constructor arguments so the wrong (null) value lands in the receiver slot.
