How to count the a specific value on a multidimensional array c#(Unity)

I'm having trouble on counting the number of my TIE value in my list
here is my code :
string[,] table = new string[104, 15];
int xIndex = 0;
int yIndex = 0;
for (int i = 0; i < list.Count; i++)
{
newString[0] += list[i].r;
newString[0] += ",";
}
string[] newChars = newString[0].Split(',');
string result = ""; // variable for the substring
string previousValue_ = ""; // store here the newprevious value without the T
int counterForTie = 0;
int counterForRow = 1;
int justMoveToY = 1;
foreach (string previousValue in newChars)
{
//check the length so that it wont throw an error
if (previousValue.Length > 1)
{
//get only the first letter of value P,B,T
result = previousValue.Substring(0, 1);
}
else
{
result = "";
}
if (table.GetLength(0) < xIndex)
{
break;
}
if (result.Equals(newPreviousValue) || result.Equals("T") && yIndex < table.GetLength(1))
{
if (counterForRow == 1)
{
yIndex = 0;
table[xIndex, yIndex] = result;
counterForRow++;
if (firstDragonTail)
{
counterForTieSecondTime++;
}
else if (secondDragonTail)
{
counterForTieThirdTime++;
}
else
{
counterForTie++;
}
}
else
{
yIndex += 1;
table[xIndex, yIndex] = result;
if (firstDragonTail)
{
counterForTieSecondTime++;
}
else if (secondDragonTail)
{
counterForTieThirdTime++;
}
else
{
counterForTie++;
}
}
}
else if (result.Equals(newPreviousValue) && previousValue.Equals("T") && yIndex < table.GetLength(1))
{
yIndex += 1;
table[xIndex, yIndex] = result;
if (firstDragonTail)
{
counterForTieSecondTime++;
}
else if (secondDragonTail)
{
counterForTieThirdTime++;
}
else
{
counterForTie++;
}
}
else
{
if (justMoveToY == 1 && counterForRow == 1)
{
xIndex = 0;
yIndex = 0;
table[xIndex, yIndex] = result;
justMoveToY++;
counterForRow++;
}
else if (justMoveToY == 1)
{
xIndex = 0;
yIndex += 1;
table[xIndex, yIndex] = result;
justMoveToY++;
}
else {
if (firstDragonTail)
{
xIndex += 1;
yIndex = 0;
table[xIndex, yIndex] = result;
counterForTieSecondTime = 0;
if (counterForTieSecondTime == 0)
{
secondDragonTail = true;
firstDragonTail = false;
}
else
{
secondDragonTail = false;
}
}
else if (secondDragonTail)
{
xIndex += 1;
yIndex = 0;
table[xIndex, yIndex] = result;
counterForTieThirdTime = 0;
if (counterForTieThirdTime == 0)
{
thirdDragonTail = true;
secondDragonTail = false;
}
else
{
thirdDragonTail = false;
}
}
else
{
xIndex += 1;
yIndex = 0;
table[xIndex, yIndex] = result;
counterForTie = 0;
}
}
}
previousValue_ = result;
if (!result.Equals("T"))
{
newPreviousValue = previousValue_;
}
}
My problem here is that i couldn't count separately all the TIE value . All i want just to count the TIE value on every column .
For example like this image
As you can see on the image above i want to know if the TIE value is on the PLAYER value(blue) / BANKER value(red) and count the TIE value if how many is it on the Player column and vice versa.
I tried this
//count tie in a row
if (result.Equals("T") && result.Equals("P"))
{
tieCounterPlayer++;
Debug.Log("TIE FOR PLAYER :" + tieCounterPlayer);
}
else if(result.Equals("T") && result.Equals("B"))
{
tieCounterBanker++;
Debug.Log("TIE FOR BANKER :" + tieCounterBanker);
}
But unfortunately it didn't work.

Sorry for asking
This is what i did.
if (newPreviousValue.Contains("B"))
{
if (result.Equals("T"))
{
tieCounterBanker++;
Debug.Log("TIE FOR BANKER : " + tieCounterBanker);
}
else
{
tieCounterBanker = 0;
}
}
else if(newPreviousValue.Contains("P"))
{
if (result.Equals("T"))
{
tieCounterPlayer++;
Debug.Log("TIE FOR PLAYER : " + tieCounterPlayer);
}
else
{
tieCounterPlayer = 0;
}
}

Wait 20 Seconds In Timer Before Executing Next Line Without Thread.Sleep.C#

I think it might be easy but not for me, Because i'm new to c#

First off, Tim S's answer -- break up your logic into smaller chunks and simplify the timer logic -- is good. But to answer your specific question, which was "how do I delay between statements without Sleep", is: make the method async and then use await Task.Delay(...).
You are right to avoid Sleep; using it is a bad programming practice, and will hang your application. await Task.Delay does an asynchronous wait -- that is, the method returns immediately, the app keeps on processing UI messages, and when the delay is done, the program schedules the remainder of the method to execute later.
Note that during an asynchronous wait, by design messages keep on getting processed. If one of those messages causes your event handler to run again then you can get into the very confusing situation of having multiple control points in the same non-recursive method. Try to avoid that.

Right now your logic is convoluted, and probably very different from what you want it to do.
Your code will be much simpler if you put your webBrowserX and userIdLabelX items in some sort of list together.
public class MyPair
{
public WebBrowser WebBrowser { get; set; }
public Label UserIdLabel { get; set; }
}
private List<MyPair> pairs;
private int refreshIndex = 0;
private void StartTimer()
{
pairs = // populate pairs somehow
refreshIndex = 0;
var timer = new System.Windows.Forms.Timer();
timer.Interval = 20000
timer.Tick += MyTickHandler;
timer.Start();
label18.Text = "Timer Activated";
}
private void MyTickHandler(object sender, EventArgs e)
{
pairs[refreshIndex].WebBrowser.Refresh();
pairs[refreshIndex].UserIdLabel.BackColor = Color.Red;
label20.Text = "+" + (refreshIndex + 1);
refreshIndex = (refreshIndex + 1) % pairs.Count;
}
Note that this timer never deactivates, it loops through the list of pairs repeatedly.

searching an array for specific criteria and displaying

Hi I am completely new to C# programming and I am getting stuck on my code. My program is to ask the user for a city or zip code, the amount of beds/baths they want, and their price range. I need to to search through my array and then display all the houses that meet their criteria (think Zillow, the website). My code currently displays random houses that do not meet any of the criteria I selected for the home. HELP!

How to prevent stack overflow error in javascript?

I have a javascript function called MakeInput.
It has got approximately 150 lines.
And I have to call that function about 300 times in my code.
My C# code called that function through webbrowser control.
It has to call that function 300 times, until DataTable in C# finishes looping.
But maybe javascript in webbrowser thinks that I am calling an infinite recursive function, so when it comes to about 60 times, it always throws an error called stack overflow at line 38.
How can I prevent this error?
How can I do a long time function in javascript?
EDIT
OK.
I am posting my code.
Here it goes.
C#
ieBrowser.Document.InvokeScript("setPageIndex", new object[] { currentPage });

And the error message was captured.
Sorry, the error message is written in Korean.
But it says, "Stack overflow(at line 38)".
But I think the number is not pointing at the line number, coz I've changed lines but the error message is always 38.

It doesn't think you are in a continuous loop. It fails when memory runs out in stack. The same code might work on a computer with higher memory. Each time a function is called a stack entry is kept in stack to move to calee once the function is done, so in your case the stack space runs out after 60 calls. The line 38 is not line number in your code.
Why dont you try same code on a high end PC

ask for confirmation when checking a box

i currently have a form that has several check boxes, once all the boxes are checked or left empty, it sends it to the database the state of the check boxes
i want to add, if a box is not checked, when you check it, it should ask for confirmation window "you sure you wanna check this"
any help please?
this is the current code
public IMeditor(IMui IMui, IMuser U, string User)
{
InitializeComponent();
this.IMui = IMui;
imu = U;
if (imu.UID == 0)
{
Add.Text = "Add";
imu.name = user;
}
else
Add.Text = "Update";
AuthChat.Checked = imu.AuthChat == 1;

case "aim": Transport.SelectedIndex = 0; break;
case "gtalk": Transport.SelectedIndex = 1; break;
case "msn": Transport.SelectedIndex = 2; break;
case "yahoo": Transport.SelectedIndex = 3; break;
}
}

I agree with Izzy. Add something like
private void PrivateInitialize()
{
CheckBox chkBox = new CheckBox();
chkBox.Text = "Click me";
chkBox.CheckedChanged += new EventHandler(chkBox_CheckedChanged);
}
private void chkBox_CheckedChanged(object sender, EventArgs e)
{
MessageBox.Show("Nag, nag, nag! You take out the trash yet?");
}

You need to handle the event CheckedChangedEvent for the checkbox. You can find the sample code on MSDN. Also
this link for the complete understanding of checkbox.
Or else you can derive your own class from CheckBox control of windows forms then override the required function and implement your own logic and create all the checkboxes in your application from this derived class

public IMeditor(IMui IMui, IMuser U, string User)
{
InitializeComponent();

do it with javascript? add OnClientClick="return confirmCheck(this);"
<script language="javascript">
function confirmCheck(e){
return confirm("are you sure?");
// do other stuff
}
</script>
this should be better than redirecting people
