do not be tired
I defined a 1000-element presentation in the Windows application form space and used it in various areas of the program, but unfortunately I encounter the following error. Thank you for your help:
enter image description here
I have defined this variable as follows :
enter image description here
Indexes in arrays start with 0. So array with 1000 elements will have indexes from 0 to 999. It throws at the 1000th index. As a solution, you can change your loop to have following condition: i < 1000 instead.

I was reading the source code of the dictionary and came across the resize method. I saw the formula temp = (currentSize * 2), currentSize = GetNextPrimalNumber(temp). Why we must to set primal number as a dictionary size? https://referencesource.microsoft.com/#mscorlib/system/collections/generic/dictionary.cs,440
Can somebody explain why we should use primal numbers as a size of dictionary? Thanks a lot !

This was working befor but its stopped and i don't know why this message just keeps coming up:
ArgumentOutOfRangeException: Argument is out of range. Parameter name:index
At a guess, you're not populating the list SpawnPrefabs or, at least, not populating it enough to have an element at one of the indexes that you're referencing.

I am trying to create a two dimensional numeric array in c#. In which there are the following simple methods: generates the array, shows the array results in the console and finally counts and shows the sum of all of the rows and columns in it.
But when i am trying to get the sums of rows and columns i get this error:
The number of rows and columns are specified in the first row of the data.txt file.(5 rows and 7 columns)
The data.txt file looks like this:
This is my first post in SOF so i apologize for any mistakes.
thanks in advance.
Assuming column count != row count - it should be
result = new int[columns] instead of result = new int[rows]
since you initialize result with result = new int[rows] and i is iterating the columns

Why does 0.ToString("#.##") return an empty string instead of 0.00 or at least 0?

I have several decimal numbers that I need to show as strings (no need for decimal places). I use the following code:
mytextblock.text= mydecimalnumber.ToString("#");
However this code will show nothing if the number is 0. I need to display a "0" instead of an empty string. I can do this using if and else but I don't think this is the best solution to do with many decimal variables.
Some user "David.." posted this answer and it worked for me but then he deleted it later:
He mentioned that ToString("#") will only show digits that are not zeros.
In order to default to 0, I should use ToString("0")

I have an int that is passed through to the a view and it need to formatting so it is not one big block of number. e.g
0
00
000
000,0
000,000
000,000,000
How can i do this using a for loop?
thanks
You may want to output the integer as i.ToString("###,###,###");
However, this would not display a value if the int is 0.
You could try using System.Drawing.Color to represent the colour value rather than an int. This has a method ToArgb()
