WinForms-何时调用Dispose?什么时候隐式? [英] WinForms - when to call Dispose? When is it implicit?
问题描述
我正在使用.NET MemoryProfiler查找我的应用程序中的内存泄漏，而在创建和显示Winform时，我似乎无法弄清楚何时应该调用Dispose()的模式.看来，当我这样做
I was using .NET MemoryProfiler to look for memory leaks in my app and I can't seem to figure out the pattern of when I should call Dispose() when it comes to creating and showing winforms. It seems that when I do
Form frm = new SomeForm();
frm.ShowDialog();
bool test = frm.IsDisposed()
test是"False"，这令我感到惊讶，.NET MemoryProfiler还确认未正确处理该表格.我以为如果我关闭(X)"对话框，它将在表单上有效地调用.Dispose()，但事实并非如此.我很好奇，如果我这样做:
test is "False" which is surprising to me and .NET MemoryProfiler also confirms that the form wasn't disposed of properly. I thought if I "Close (X)" the dialog then it would effectively call .Dispose() on the form but doesn't seem to be the case. I am curious what would happen if I do:
Form frm = new SomeForm();
frm.Show();
当我单击表单上的关闭(X)"按钮时，该表单会被丢弃吗?我试图找到一条规则，何时应该调用"Dispose()"，何时不需要调用"Dispose"(因为它将被隐式处置)...
Would the form be disposed when I click the "Close (X)" button on the form? I am trying to find a rule when I should call "Dispose()" and when I don't need to call "Dispose" (because it will be disposed implicitly)...
