How to convert 2d array to 1d array ?

Suppose you to insert or get the values from 1d array using 2d dimensions like :-
Insert value at (1,2) and the value is 5 then you have to find the logic to get the index :-
Firstly you have to know the size of 2d array here suppose :- (2x3)

int xPosition = 1;
int yPosition = 2;

3 is ySize of 2d array.
int 1dIndex = (3*xPosition)+ yPosition ;

Insert at this index or get from this index.

How to convert 3d array to 1d array ?

Suppose you have to insert a value at (2,1,0) and the value is :-5
means firstly you have to find the index through (2,1,0) then you have to insert value 5 at that index .

Logic is :-
Firstly you must have to know the 3d array size suppose here is (3x2x3).
int xPosition = 2;
int yPosition = 1;
int zPosition = 0;

int indexOf1dArray = (xPosition *2*3) + ((yPosition * 3)+zPosition) ;

Using this insert the value at this index indexOf1dArray and if you have to get the value then again find index using this method and then find the value at this place.

What is the difference between .ToString() and Convert.ToString() ?

int value = 3;
string stringConversion = value.ToString();
string stringConversion = Convert.ToString(value);

We can convert the integer “value ” using “value .ToString()” or “Convert.ToString”
The basic difference between them is “Convert” function handles NULLS .It handles null exception while “value .ToString()”does not it will throw a NULL reference exception error. So as good coding practice using “convert” is always safe.

Happy to code...
