我有一个VB.Net控制台应用程序正在运行,我不希望它在用户点击ENTER按钮时关闭,而是我希望它在键入时关闭EXIT,然后按下ENTER.我该怎么办?
(不,这不是家庭作业,我刚刚发现了这个bug,并认为在这里分享可能有用)

swap(list, i, i + 1);
didWork = true;
break;
}
}

return;

如何使用LINQ从对象集合中获取MaxTime和MinTime?

Category | Count ------------------- A | 2 B | 2 Z | 2 A_B | 1 A_B_C | 5
我正在寻找一个查询,它总结以普通字母/字符串开头的类别数,所以从上面我要找的结果如下:
Category | Count ------------------- A | 8 <- (a sum of A, A_B, A_B_C) B | 2 Z | 2 A_B | 6 <- (a sum of A_B, A_B_C) A_B_C | 5
