Please stop reposting this question. You have received enough reasons why returning arrays (whether static or not) from a method is a bad idea.

We have no idea what you are trying to do so we cannot comment. if you have a problem that you need help with then please provide proper details.

Sir I have learned how you can use one integer or string value of one class to another class by the use of property. So I used the same for array. But it showed compiler warning--property should not be used to return arrays. So I asked for help that how you would return array from a method without declaring static....

Richard MacCutchan 11-Jul-20 12:03pm

How many times do you need to hear this: do not return arrays from other methods. Whatever you are trying to do (and you still have not explained it) your design is wrong, and needs to be reviewed.

Sir I'm trying to make a database, where I would need this thing....
One more thing just came in my mind now....make a 4D image processing application...

Richard MacCutchan 11-Jul-20 12:19pm

I can see no good reason why you would need a 3D array to make a database. And I have no idea what 4D images are.

Member 12712527 11-Jul-20 12:21pm

There are objects of 4D in the universe....

Richard MacCutchan 11-Jul-20 12:25pm

Maybe so, but there are only 3 dimensions on earth.

Member 12712527 11-Jul-20 12:30pm

How to built a database of 4D...!!!

Richard MacCutchan 11-Jul-20 12:33pm

You are really wasting your time with this question. Get a book, or work through some tutorials on programming and databases. You are not going to learn either of them in a Quick Answers forum.

Okay I'll not return the array from any method but can I return the array itself...

Richard MacCutchan 11-Jul-20 12:23pm

Forget arrays, whatever you are trying to do you are going wrong. But, as I mentioned before, you have not given us any idea what actual problem you are trying to solve.

Member 12712527 11-Jul-20 12:36pm

A variable contains only one value, an array has multiple values but looses its value if called from outside. How to retain the value in a variable is learnt. But I didn't know how to retain the values in an array without declaring it static....I WANT TO DO THAT.......

Richard MacCutchan 11-Jul-20 12:37pm

Like I said above, get yourself a book on programming.

Member 12712527 11-Jul-20 13:11pm

It's like returning pointers from function in C....
What would you say if I use the ref keyword....?

Member 12712527 11-Jul-20 13:14pm

void abc(out ref string arg)

Member 12712527 11-Jul-20 13:27pm

Sir what's your answer still get a book...?

Richard MacCutchan 11-Jul-20 13:37pm

Yes.

Member 12712527 11-Jul-20 14:17pm

What will you do.....
public IntPtr func()
{
private string[] arg;
Do some work with arg....
and
return arg;
}

Is this way correct...?

Richard MacCutchan 12-Jul-20 4:24am

No.

I don't want to use static arrays in the program. But in case if I don't find any solution...I have to use it...This will cause issue in my program as I learned from someone that static variable r array is not collected by the garbage collector....So the program will have issues....
