如何使用锯齿状阵列收集信息？ [英] How to collect information with a jagged array?

问题描述

Hello. I am a new guy to C# (going for a master degree), so my teacher jumped streight to giving us homework. So, what I need to do is : to collect data about student's marks using jagged arrays.

1st: we must introduce data about the list of courses using a vector....

2nd: we must introduce data about the list of students using a vector...

3rd: we must generate a random irregulated parallelepiped using the marks of each student at each course...

Frankly, I have no ideea how to do this and my teacher isn't helping me either, he's not explaining very well, can you help me?

我的尝试：

What I have tried:

string [][][] stud = new string[4][5][8];

这就是我能想到的......

That's all I could come up with...

推荐答案

锯齿状数组是一个n维数组的数组< br $> b $ b

Jagged array is an array of n-dimensional arrays

'a one dimensional array accepts no arrays, simply objects

Dim oneDArray（）As Integer = {4,5,8}

Dim oneDArray() As Integer = {4, 5, 8}

'a two dimensional array accepts only arrays and that of one dimensional

Dim twoDArray（）（）As Integer = {oneDArray，anotherOneDArray，etc1 ..}



Dim threeDArray（）（）（）As Integer = {twoDArray，anotherTwoDArray，etc2 ......，another_etc2 ....}





threeDArray（0）返回twoDArray

threeDArray（1）返回anotherTwoDArray

threeDArray（2）返回etc2 ......

threeDArray（3）返回another_etc2 ...



threeDArray（0）（0）返回oneDArray

threeDArray（0）（0） （0）返回4.（见上文{4,5,8}）

Dim twoDArray()() As Integer = {oneDArray, anotherOneDArray, etc1..}

Dim threeDArray()()() As Integer = {twoDArray, anotherTwoDArray, etc2..., another_etc2....}


threeDArray(0) returns twoDArray
threeDArray(1) returns anotherTwoDArray
threeDArray(2) returns etc2...
threeDArray(3) returns another_etc2...

threeDArray(0)(0) returns oneDArray
threeDArray(0)(0)(0) returns 4. (see above {4,5,8})
