.net {“试图读取或写入受保护的内存。这通常表示其他内存已损坏。”

我围绕Unity构建了一个简单的应用程序框架。也就是说，表单和用户控件被描述为xml并动态构建。我有一个表单，其中包含一个组合框，当它关闭时会导致下面详细说明的错误。如果用ComboBox代替ListBox控件，则不会出现此问题

有人在谷歌上搜索了一些关于我没有安装补丁的报道

当控件使用XP/Vista样式，然后在旧版本的Windows上运行时，我见过这种情况

我在系统上安装新字体时看到了这个错误。您最近是否安装了新字体或安装了新字体的程序

其他.net程序是否正常运行？如果没有，最好是重新安装.NET framework。

当我的.NET应用程序运行时，在Windows XP上尝试将系统显示切换为“超大字体”时，请点击此按钮

这可能与错误的字体或类似字体有关
