我试过用这种方法除去苏打水，但我不能把我的头挪到哪里出错了。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | if (myCrate == null) { Console.WriteLine("Your crate is empty."); Console.ReadKey(); return; } Console.WriteLine("Name on the bottle:"); string name = Console.ReadLine(); if (myCrate.Select(x => x.Flavor).Contains(flavors)) { var itemToRemove = myCrate.Where(x => x.Flavor.Equals(flavors)).First(); if (itemToRemove != null) myCrate.Remove(itemToRemove); } else { Console.WriteLine("Name not found."); Console.ReadKey(); } |
这是我的高贵尝试，在某种程度上实现泡沫
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | public void sort_sodas() { int max = myCrate.Length - 1; //outer loop: Goes through the entire list until everything's sorted for (int m = 0; m < max; m++) { //inner loop: Goes through every element and comparing them to eachother. Doesn't go through what's already sorted. int sorted = max - m; //to see how many has been gone through for (int n = 0; n < sorted; n++) { if (myCrate[n] > myCrate[n+1]) //comparing elements { //switch place int temp3 = myCrate[n]; myCrate[n] = myCrate[n+1]; myCrate[n+1] = temp3; } } } //write the list for (int m = 0; m < myCrate.Length; m++) Console.WriteLine(myCrate[m]); } |
但是，它给了我3个错误。
1:运算符">"不能应用于"瓶子"和"瓶子"类型的操作数。
2:无法将类型"sodacrate.bottles"隐式转换为"int"
3:无法将类型"int"隐式转换为"sodacrate.bottles"
所以如果我小于25，它就永远不等于25
数组是为固定不变的数据而设计的，我建议使用列表
1 |
然后你可以做
1 2 3 4 5 6 7 8 | if (Crate.Count >= 25) { Console.WriteLine(" - Your crate is full!"); } else { Crate.Add(bottle); } |
对于分组结果，Linq是您的朋友
1 | crate.Groupby(b=>b.Flavor).Select(g=>g.Count() +"" + g.Key); |
将返回可枚举的字符串
你也可以用Linq的
1 | crate.Orderby(b=>b.Price) |
也可以使用Linq的
1 | crate.Where(b=>b.Flavour == SearchField) |
编辑：更明确一点添加函数应该如下所示
1 2 3 4 5 6 7 8 9 10 11 | adding = int.Parse(Console.ReadLine()); if (amountBottles >= 25) { Console.WriteLine(" - Your crate is full!"); } else { //Your Switch statement here amountBottles++; } |
你的指纹应该是
1 2 3 4 5 6 7 8 9 10 11 12 | for (int i = 0; i < myCrate.Length; i++) { if (myCrate[i] != null) { Console.WriteLine( myCrate[i].Flavor ); } else { Console.WriteLine("Empty Space"); } } |
编辑：就像你想用out-linq进行分组和排序一样然后，对于分组，您需要创建一个组类，该组类将保存您的瓶子类型和计数，同时生成总数s，然后使用该组进行打印。
对于排序，那么您需要实现一个排序算法，最好是快速排序，尽管插入排序更简单。
