我知道C#是一种自动垃圾收集语言,但是如果我处理表单会不会有所不同?例如:
SettingsDialog dialog;
private void settingsToolStripMenuItem_Click(object sender, EventArgs e)
{
dialog = new SettingsDialog();
dialog.ShowDialog();
dialog.FormClosed += new FormClosedEventHandler(dialog_FormClosed);
}
void dialog_FormClosed(object sender, FormClosedEventArgs e)
{
dialog.Dispose();
}
或者我应该将其保留为:
private void settingsToolStripMenuItem_Click(object sender, EventArgs e)
{
SettingsDialog dialog = new SettingsDialog();
dialog.ShowDialog();
}
另外,如果SettingsDialog占用大量内存怎么办?这会有所作为吗?
提前致谢
最佳答案
只需使用:
using(SettingsDialog dialog = new SettingsDialog())
{
dialog.ShowDialog();
}
这将自动处理
dialog
。关于c# - 用完表格后需要处理吗?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/7734879/
