C# code invoke parameters count dosen't match

Question

is there anyone check my code? it shows the parameter count dose not match.

    void WriteFaceLog(string userID, string faceId, string size, string valid, string template)
    {
        if (lstvFace.InvokeRequired)
        {
            Action<string, string, string, string, string> action = WriteFaceLog;
            this.Invoke(action, faceId, size, valid, template);
        }
        else
        {
            ListViewItem item = new ListViewItem(userID);
            item.SubItems.AddRange(new[] { faceId, size, valid, template });
            lstvFace.Items.Add(item);
        }
    }

You miss `userId` in `Invoke`. – Sinatr Mar 20 '17 at 09:42 — Sinatr, Mar 20 '17 at 09:42

The typical auto-invoke pattern (designed to simplify running method from any thread) will looks like this in your case:

void WriteFaceLog(string userID, string faceId, string size, string valid, string template)
{
    if (this.InvokeRequired) // you can use lstvFace instead of this, it doesn't matter as both are in same thread, you can also omit this
        this.Invoke((MethodInvoker)delegate { WriteFaceLog(userID, faceId, size, valid, template); });
    else
    {
    }
}

In given case you are unlikely to miss any parameter (just re-pass them).
