Debug.Log() A 2D array from a custom class to main class

Here's my code.
CustomClass.cs
class ScoreBoard(){
private int m_lastCnt;
public ScoreBoard{
m_lastCnt = 0;
}
public void makeBoard(string history) {
string[] arrPartStr = history.Split(',');
int[] arrPart = new int[arrPartStr.Length];
for (int c = 0; c < arrPart.Length; c++)
{
int temp = 0;
if (arrPartStr[c][0] == 'P') temp = 100;
else if (arrPartStr[c][0] == 'B') temp = 200;
else temp = 300;
if (arrPartStr[c][1] == 'P') temp += 10;
if (arrPartStr[c][2] == 'P') temp += 1;
arrPart[c] = temp;
}
//var strTmp : String = strData;
//strTmp = "311|101|211|211|211|211|211|211|211|211|111|111|111|111|111|111|111|111|111"
//strTmp = strData.replace(/:/g,"");
int[,] arrTmp = new int[6100, 104];
}
}
Main Class i call the void method like this
ScoreBoard sb = ScoreBoard();
string history = "s ,o ,m ,e ,s ,t ,r ,i ,n ,g";
private void Start(){
sb.makeBoard(history);
}
How can i print my 2D array in my console?
I tried doing it like the for(int row){for(int col){}} but its not working i don't know why

Do you mean this?
for (int j = 0; j < arrTmp.GetLength(1); j++)
{
for (int i = 0; i < arrTmp.GetLength(0); i++)
{
var msg = "[" + i.ToString() + ", " + j.ToString() + "] = " + arrTmp[i, j].ToString();
Debug.Log(msg);
}
}

I got it to display:)
CustomClass.cs
int[,] arrTmp = new int[104, 6];
public int[,] GetBoard(){ return arrTmp }
MainClass.cs
int[,] arrayBigRoad = bsb.GetBoard();
for (int j = 0; j < arrTmp.GetLength(1); j++)
{
for (int i = 0; i < arrTmp.GetLength(0); i++)
{
var msg = "[" + i.ToString() + ", " + j.ToString() + "] = " + arrTmp[i, j].ToString();
Debug.Log(msg);
}
}
Thanks though Rodrigo . I'll mark yours as an answer

Copying single cell value from one Excel document to another Excel document using C#

}
My problem is in the line:
Krajnji_PoMT.Cells[(x + 12), kolumna].Value = Polazni.Cells[(x + 12), kolumna].Value;
I tried many variations but I can never get that value pasted to another Excel. If I say:
Krajnji_PoMT.Cells[(x + 12), kolumna].Value = "test";
then it works. Whats the catch here?

Extract a table from PDF

I need a help with iText in C#. I'm trying to extract a table from a PDF file and save this into a new CSV file, keeping the values in the correct places. For this, I thought the solution was to create a two-dimensional array to organize the data.
Extracting all information from PDF with iText, I saw it was possible to get some numerical data that seemed to be the position of a piece of text on the page and I organized my array based these indexes. It didn’t work, the text was completely dispersed in various different cells. Now, I want to know what this values means, because they don't follow a "correct" order and I want to know if is possible to organize the future table with this.
I'm using ";" as delimiter cell.
For testing, I'm using this PDF

C# Compare 2 strings, sorting, put into array

hi im formulating my question now better.
in the foreach command i get for temp(save variable) values in an array. The values that i save in temp are from the datagridview cells.
in the next step, in the for command, i want to compare 2 strings, the string and the next string, if the fist string is bigger than the second, i want to change their positions. But there is the problem, they dont change positions they even get an empty value, and i cant understand why they get an empty value.
Im thinking that they get an empty value because of the foreach command, the index [i] just stays the same, but if i would put in i = i+1, the command would be out of bound.
Thank you
senc. NIko
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (row.Cells[i].Value == null)
{
//MessageBox.Show("This row is empty");
break;
}
if (row.Cells[i].Value != null)
{
temp = row.Cells[i].Value.ToString();
UnsortArray[i] = temp;
i = i + 1;
}
}
for (int a = 0; a < MaxZeilen; a++)
{
if (i < MaxZeilen)
{
*if (String.Compare(UnsortArray[a], UnsortArray[a + 1]) > 0)
{
UnsortArray[a] = temp;
UnsortArray[a + 1] = temp2;
temp = UnsortArray[a + 1];
temp2 = UnsortArray[a];
}*
}
}
for (int i = 0; i < MaxZeilen; i++)
{
UnsortArray[i] = SortArray[i];
MessageBox.Show(UnsortArray[i]);
}

You're backwards, assigning the array to your temp variables before assigning the temp variables:
UnsortArray[a] = temp;
UnsortArray[a + 1] = temp2;
temp = UnsortArray[a + 1];
temp2 = UnsortArray[a];
Try:
temp = UnsortArray[a + 1];
temp2 = UnsortArray[a];
UnsortArray[a] = temp;
UnsortArray[a + 1] = temp2;
And you've done it again here UnsortArray[i] = SortArray[i];. I think you mean SortArray[i] = UnsortArray[i];

temp = UnsortArray[a + 1];
UnsortArray[a + 1] = UnsortArray[a];
UnsortArray[a] = temp;
instead of
UnsortArray[a] = temp;
UnsortArray[a + 1] = temp2;
temp = UnsortArray[a + 1];
temp2 = UnsortArray[a];

Why using an array and not a List ?
This page tells about sorting lists.

Here is some improvements to your code. You had an error at the top that could cause a infinite loop and just use the Array.Sort method. If you want it to sort differently, add an IComparable interface.
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (row.Cells[i].Value == null)
{
//MessageBox.Show("This row is empty");
i++;
break;
}
else (row.Cells[i].Value != null)
{
UnsortArray[i] = row.Cells[i].Value.ToString();
i++;
}
}
Array.Sort(UnsortArray);
SortArray = UnsortArray;

List<String> itemList = new List<string>();
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (row.Cells[0].Value = null)
{
itemList.Add(row.Cells[0].Value.ToString());
}
}
itemList.Sort();
string[] SortedArray = itemList.ToArray();
for (int j = 0; j < SortedArray.Length; j++)
{
MessageBox.Show(SortedArray[j]);
}
and if this code doesn't work, than add
foreach(string item in itemList)
{
MessageBox.Show(item);
}
after first foreach loop and check the values

Replace it with the following code block
int i= 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (row != null)
{
temp = row.ToString();
UnsortArray[i] = temp;
i = i + 1;
}
}
for (int a = 0; a < MaxZeilen; a++)
{
if (String.Compare(UnsortArray[a], UnsortArray[a + 1]) > 0)
{
temp = UnsortArray[a + 1];
UnsortArray[a + 1] = UnsortArray[a];
UnsortArray[a] = temp;
}
}
for (int i = 0; i < MaxZeilen; i++)
{
MessageBox.Show(UnsortArray[i]);
}

int MaxArrayCount = 0;
foreach(DataGridViewRow row in dataGridView1.Rows)
{
MaxArrayCount += row.Cells.Count;
}
string[] UnsortArray= new string[MaxArrayCount];
int cnt = 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
for (int i = 0; i < row.Cells.Count; i++ )
{
if (row.Cells[i].Value != null)
{
temp = row.Cells[i].Value.ToString();
UnsortArray[cnt] = temp;
cnt++;
}
}
}
for (int b = 1; b < UnsortArray.Count; b++)
{
for (int a = 0; a < UnsortArray.Count - 1; a++)
{
if (String.Compare(UnsortArray[a], UnsortArray[a + 1]) > 0)
{
temp = UnsortArray[a + 1];
UnsortArray[a + 1] = UnsortArray[a];
UnsortArray[a] = temp;
}
}
}
for (int i = 0; i < MaxZeilen; i++)
{
MessageBox.Show(UnsortArray[i]);
}

C# How to exclude an int from an array?

So I've got an array of integer. I want to use a loop and exclude integers that makes the equation true. So that would be like
for (int n = 0; n < first9char.Length; n++ ) {
if (first9char[n] == clickValue) {
first9char[n] = first9char[n + 1];
But then it only changes the value that is equal to not changing whole array. So is there any way to do this?
I want to use it in this loop.
if (UserSquareMethod.clickedBoxes[0] == -1) {
MessageBox.Show("You have not selected any box");
} else {
int i = 0;
do {
if (textButtonArray[clickedBox[i]].Text == "" || clickValue == "") {
textButtonArray[clickedBox[i]].Text = clickValue;
textButtonArray[clickedBox[i]].Font = new Font(textButtonArray[clickedBox[i]].Font.FontFamily, 14, FontStyle.Bold);
}
else
{
textButtonArray[clickedBox[i]].Text += "," + clickValue;
textButtonArray[clickedBox[i]].Font = new Font(textButtonArray[clickedBox[i]].Font.FontFamily, 5, FontStyle.Regular);
string[] first9char = textButtonArray[clickedBox[i]].Text.Split(new string[] { "," }, StringSplitOptions.None);
for (int j = 1; j < first9char.Length; j++)
{
for (int k = j - 1; k >= 0; k--)
{
if (first9char[j] == first9char[k])
{
if (clearNumberClicked == true)
{
first9char = Array.FindAll(first9char, x => x != clickValue);
label2.Text = first9char[0];
//int n = 0;
//for (int p = 0; p < first9char.Length; p++)
//{
// if (first9char[p] != clickValue)
// {
// first9char[n] = first9char[p];
// n++;
// label2.Text += "," + first9char[n];
// }
// }
//for (int n = 0; n < first9char.Length; n++ ) {
//if (first9char[n] == clickValue) {
// first9char[n] = first9char[n + 1];
// for ( int p = 0; p < n; p++) {
//}
//}
//}
MessageBox.Show("Clear the number" + first9char[(first9char.Length - 1)] + "and " + clickValue + " " + first9char.Length);
}
else {
first9char[j] = "";
textButtonArray[clickedBox[i]].Text = first9char[0];
MessageBox.Show("You cannot enter the same number again!"+ first9char[j]+j);
for (int m = 1; m < (first9char.Length - 1); m++) {
textButtonArray[clickedBox[i]].Text += ","+ first9char[m];
}
}
}
}
}
if (textButtonArray[clickedBox[i]].Text.Length > 9)
{
textButtonArray[clickedBox[i]].Text = first9char[0] + "," + first9char[1] + "," + first9char[2] + "," + first9char[3] + "," + first9char[4];
MessageBox.Show("You cannot enter more than 5 numbers, please clear the box if you want to enter different number." + textButtonArray[clickedBox[i]].Text.Length);
}
}
i++;
}
while (clickedBox[i] != -1);
}
}

I would use LINQ for this:
first9char = first9char.Where(x => x != clickValue).ToArray();
It just means "pick the items that don't match". If you can't use LINQ for some reason, then just keep another counter, and make sure to only loop to n from there on in:
int n = 0;
for(int i = 0; i < first9char.Length; i++) {
if(first9char[i] != clickValue) {
first9char[n] = first9char[i];
n++;
}
}
Clean and efficient.
