是否有解决办法的ToolStrip不内存泄漏 [英] Is there a workaround for ToolStrip to not leak memory

问题描述

我有一个简单的表格（MainForm中）打开另一种形式（子窗体），其中有一个ToolStrip的就可以了。

I have a simple form (MainForm) that opens another form (SubForm) which has a ToolStrip on it.

没有什么别的被叫形式。调用形式只有一个按钮。

There is nothing else on the called form. The calling form only has a button.

这被称为是永远不会回收，因为有一个事件处理程序的SystemEvents.User preferenceChanged形式的记忆。我看这是得到了修复.NET 3.5.1的问题。

The memory of the form that is called is never reclaimed because there is an eventhandler for SystemEvents.UserPreferenceChanged. I read that this is an issue that got fixed in .NET 3.5.1.

[修改应用程序上运行3.5.1或者让它不是真的固定或我做不同的事情]

[EDIT The application runs on 3.5.1 so either it is not realy fixed or I do something different]

我能做些什么，以便GC可以回收子窗体的记忆是什么？

Can I do something so that the GC can reclaim the memory of subform?

当我删除的ToolStrip，形式子窗体可以被垃圾再收集。

As soon as I remove the ToolStrip, the form subform can be garbage collected again.

的MainForm

public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            SubForm subForm = new SubForm();
            subForm.ShowDialog();
        }
    }

子窗体

 public partial class SubForm : Form
    {
        public SubForm()
        {
            InitializeComponent();
        }
    }

实例保留图形与工具条

推荐答案

您正在显示一个对话框，但从来没有处理它，所以至少把它放在一个用（）子句，或以其他方式处置其在适当的时候。查看更多有关ShowDialog的这里

You're showing a dialog, but never disposing it, so at least put it in a using() clause , or otherwise dispose it when appropriate. See more about ShowDialog here
