我有一些冗长的代码:
@H_404_2@private bool AnyUnselectedComBox()
{
bool anyUnselected = false;
foreach (Control c in this.Controls)
{
if (c is ComboBox)
{
if ((c as ComboBox).SelectedIndex == -1)
{
anyUnselected = true;
break;
}
}
}
return anyUnselected;
}
…… Resharper提供了一个像这样的LINQ表达式的elegantize:
@H_404_2@return this.Controls.OfType<ComboBox>().Any(c => (c as ComboBox).SelectedIndex == -1);…但随后的Resharper检查说明了它生成的代码(上图):“类型转换是多余的”(指“c作为ComboBox”部分),因此它最终为:
@H_404_2@return this.Controls.OfType<ComboBox>().Any(c => c.SelectedIndex == -1);
