将变量值分配给多维数组 [英] Assign variable values to a multidimensional array

问题描述

如何在VB.net中为2维数组赋值变量？



我尝试过：



Dim arr（10,10）为整数



Dim i = 5

Dim j = 6



arr（0,0）=？

How do I assign variables to a 2 dimensional array in VB.net?

What I have tried:

Dim arr(10,10) as Integer

Dim i=5
Dim j=6

arr(0,0)=?

推荐答案

你说错了方式：

You're going the wrong way:

Dim arr(10,10) as Integer

Dim i=5
Dim j=6
arr(i,j) = 666

你已经得到了答案。

我建议你学习一些教程并学习调试器，这将是你学习的一个帮助。



你应该学会使用调试器作为尽快。而不是猜测你的代码在做什么，现在是时候看到你的代码执行并确保它完成你期望的。



调试器允许你跟踪执行逐行检查变量，你会看到它有一个停止做你期望的点。

当代码不做ex的时候你已经接近了一个错误。

You already got the answer.
I recommend to follow some tutorials and learn the debugger, it will be a graet help for your learning.

You should learn to use the debugger as soon as possible. Rather than guessing what your code is doing, It is time to see your code executing and ensuring that it does what you expect.

The debugger allow you to follow the execution line by line, inspect variables and you will see that there is a point where it stop doing what you expect.

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
When the code don't do what is expected, you are close to a bug.
