我正在開發一個應用程式，它是視頻游戲的聲音編輯器。
這個應用程式有一個選項來測驗游戲中的聲音，為此我使用帶有一些特殊引數的Process.Start來打開游戲 .exe。
游戲使用OutputDebugStringA()來列印除錯訊息。我們的想法是在此表單內有一個多行文本框，以僅顯示游戲行程的除錯訊息。
我一直在做一些研究，我從 sysinternals 知道 DebugView 的存在，但對這種情況沒有用，我還在代碼專案中找到了 DbMon.NET，但由于某種原因導致游戲運行非常緩慢（與 DebugView 不會發生）。
有什么建議嗎？

試試這個，您可以在 do while 回圈中指定行程 ID，然后再將其列印到文本框中。
