一切正常，直到窗口标题改变，让我们说＆＃34; Something 100/200＆＃34;到＆＃34;东西150/300＆＃34;。我必须获得新的价值。
这是我必须更新的代码的和平：
bigBlindAmount = hdcList[hdc];
m = m / bigBlindAmount;
string stringOut = m.ToString("N");
return DrawTextExW(hdc, stringOut, -1, ref lprc, dwDTFormat, ref dparams);
bigBlindAmount是来自apllication标题的150/300。当应用程序标题从100/200更改为15/300时，我必须将bigBlindAmount更改为150/300。
非常感谢您的回答！

我认为你可以从
获得窗口标题Process.GetCurrentProcess().MainWindowTitle
根据需要在您注入的dll中，并解析为您需要的值。
