如何获得物品的循环 [英] How to get for loop through the items

问题描述

大家好，
例如，我有两个数据集，其中第一个数据集有2个项，即item1，item2，第二个数据集有3个项，即item3，item4，item5.
我想将这些项目的结果计算为以下组合:

item1和item2
item2和item3
item3和item4
item4和item5

Hello All,
For example I have two data sets in which first dataset have 2 items namely item1,item2 and second dataset have 3 items namely item3,item4,item5.
I want to calculate result from these items as the following combination:

item1 and item2
item2 and item3
item3 and item4
item4 and item5

how for loop is executed for the above mentioned process?

推荐答案

嘿，您可以创建对象的通用列表.循环浏览两个结果集并将它们添加到列表中.假设您的商品是一个字符串:

Hey, you can create a generic list of your objects. Loop through both result sets and add them to the list. Let''s assume your items are a string :

List<string> myItems = new List<string>();

foreach (string firstListItem in firstCollection)
{
  myItems.Add(firstListItem)
}
foreach (string secondListItem in secondCollection)
{
  myItems.Add(secondListItem);
}
</string></string>

然后遍历整个结果并计算您想要的任何结果:

Then loop trough the entire result and calculate whatever you want :

for (int i = 1; i < myItems.Count; i++)
{
  // Do something with myItems[i-1] and myItems[i]
}

如果我理解正确的话?

简单的方法但不是最优化

1)
创建新的数据表.

3)添加来自table1和table2的所有数据

4)排序新的数据表

5)
indx列
[0] A
[1] b
[2] c
[3] d
[4] e
[5] f
[6] g
[7] h

求和循环
i = 0; i <= 7; i ++

sum [0] = newable [i] + newtable [i + 1];
i = i +1;


所以总和将被填充4次.

if i understand correctly?

Simple way but not optimizd

1)
Create new data table.

3) Add all data from table1 and table2

4) sort new datatable

5)
indx column
[0] A
[1] b
[2] c
[3] d
[4] e
[5] f
[6] g
[7] h

loop for sum
i=0;i<=7; i++

sum[0] = newable[i]+newtable[i+1];
i =i +1;


so sum will populated 4 time.
