我包含的工作示例代码显示了 IE 9 中的泄漏。（几分钟内 1 Gb）。当您将 V3.8 更改为 V3.7 时，不会发生此内存泄漏！！！所以我的猜测是它是在 v3.8 中引入的！该代码似乎在 Chrome/Firefox 中工作，但我正在开发一个 C# Winform 应用程序，并使用嵌入式 .NET webcontrol，一个围绕 IE 的 COM 包装器。已经尝试过 gecko .NET 组件，但这对我来说别无选择。

我被困在这里并且绝望，所以如果有人愿意提供解决方案......

谢谢罗伯

已知无作用域（和全局作用域）变量会导致内存泄漏。我建议您确保所有变量都正确地限定为函数局部变量。
