通过数组进行特殊迭代 [英] special iteration through an array

问题描述

我有一个20x16的对象数组。

我需要一种迭代数组的方法，只考虑几行和几行
列。


为了更清楚，有时我只需要前2行和后3列

循环考虑

另一次，我只需要考虑到前3列和后4行

...

无论如何，我在同一次迭代中不会有单独的行或列...

所以，从来没有像前3行和后2行......或前2列

和最后3列


只有行和列，最后是r。


任何想法如何实现？

解决方案

不是如果这是你想要的，我还没有测试过，只需用记事本写的
。


Const xSize As Integer = 20

Const ySize As Integer = 16

Dim Skips（xSize，ySize）as Boolean

Dim MyObjects（xSize，ySize）as Object

Dim xCount As Integer = 0

Dim yCount As Integer = 0


''设置全部跳到错误

For yCount = 0到yMax-1步骤1

xCount = 0到yMax-1 Step1

跳过（xCount，yCount）= False

下一页


''设置行和列以跳过例如。

Skips（9,3）= Frue


yCount = 0到ySize-1第1步


xCount = 0到xSize-1第1步


如果跳过（xCount，yCount）那么

''跳过动作

否则

''做动作
结束如果

将索引存储在2个数组中并循环遍历数组，获取2个索引数组中的

值并访问数组中的值。 />

嗨Crirus


就像其他用这封邮件写的那样真伪我想到了这个

这个

\\\

mySelectedArray as myarrayfunction（R，3,2）

函数myarrayfunction（firstIs，rows，columns）

if firstis =" ; R"然后

RowIndexStart = 0

RowIndexEnd =行

ColIndexStart = coltable.length - （列+ 1）

ColIndexEnd = coltable.length - 1

else

RowIndexStart = rowtable.length - （rows + 1）

RowIndexEnd = rowtable.length - 1

ColIndexStart = 0

ConIndexEnd = columns

结束如果

///

然后正常嵌套下一个循环

I have a 20x16 array of objects.
I need a way to iterate through the array and only consider few rows and few
columns.

To be clearer, sometimes I need only first 2 rows and last 3 columns to be
considered in loop
Another time, I whould need only first 3 columns and last 4 rows to be
considered...

Anyhow, I will not have separate rows or columns in the same iteration...
So, never something like first 3 rows and last 2 rows... or first 2 columns
and last 3 columns

only rows and columns, at the beginning r at the end.

Any ideea how to implement that?

解决方案

Not totally sure if this is what you want, I have not tested it, just
written in Notepad.

Const xSize As Integer = 20
Const ySize As Integer = 16
Dim Skips( xSize,ySize ) as Boolean
Dim MyObjects(xSize,ySize) as Object
Dim xCount As Integer = 0
Dim yCount As Integer = 0

''Setup All Skips to False
For yCount=0 to yMax-1 Step 1
For xCount=0 to yMax-1 Step1
Skips(xCount,yCount)=False
Next
Next

''Set up rows and cols to skip for example.
Skips(9,3) = Frue

For yCount=0 to ySize-1 Step 1

For xCount=0 to xSize-1 step 1

if Skips(xCount,yCount) Then
''Skip Action
Else
''Do Action
End If

Next
Next

Store the indices in 2 arrays and loop through the arrays, get the
values in the 2 index arrays and access the value in the array.

Hi Crirus

Just like the others written in this mail and true pseudo my thought about
this
\\\
mySelectedArray as myarrayfunction("R",3,2)
function myarrayfunction (firstIs, rows,columns)
if firstis = "R" then
RowIndexStart = 0
RowIndexEnd = rows
ColIndexStart = coltable.length - (columns + 1)
ColIndexEnd = coltable.length - 1
else
RowIndexStart = rowtable.length - (rows + 1)
RowIndexEnd = rowtable.length - 1
ColIndexStart = 0
ConIndexEnd = columns
end if
///
And then a normal nested for next loop
