My WindowsForm just ignore some code lines and I don't know why?

I've been programming a soft on VS in C#. It is an old program made by someone else by me but my problem is in my code I think. In this soft, there is two Form, the 1st one get some datas, and the second make the operations and also provide a report of the datas that I use.
double sum = 0;
for (int k = 0; k <= length - 1; )
{
sum += Convert.ToDouble(pisteA[k]);
k += 1;
}
double average = sum / 3;
I have an array containing Text and null values in the 2nd Form. I just want to make an average of this array, so with a for loop, I did what I have to do. But, when I launch my soft, It doesn't go through the line code and stops at this line.
sum += Convert.ToDouble(pisteA[k]);
When I use the Breakpoint to see what's happening, the code go through this line, and then go to my other form to execute this :
formImpression.Show();
To test something, I added a MessageBox.Show just after the line of the sum, and also before, and it seems that the soft execute the code above the problem line, but not the ones that are after this.
I seriously don't have any idea of what's happening.
Edit : For more comprehension about the code I use, I leave it here.

Have you this setting checked to see exception ?

Fill and 2D array from .txt file

So, I need to look through the file and fill and 2d array with data from the file. I couldn't figure any better way to do that than this, but this code just completly freezes. Here's the code.
The idea is that I'm gonna look through all of the text in a source file, then I'm gonna check if a line contains something I need and, if so, I will make additions to my 2D array, that I will then write to a different txt file.
string[,] FileBase = new string[100,100];
DateTime Date = DateTime.UtcNow;
string time = Date.ToString();
time = time.Replace(':', '.');
string ReportPath = Directory.GetCurrentDirectory() + "\\Report from " + time + ".txt";
int Value = 0;
int i = 0, j = 0;
string item;
int controlD = 0;
int sensor = 0;
int p = 0;
bool loadcell = false;
bool possensor = false;
int smth = 0;
string curr = comboBox1.SelectedItem.ToString();
curr = curr.Remove(0, curr.IndexOf("RCU") + 3);
int current = Convert.ToInt32(curr);
string localpath = path + "\\control\\RCU" + curr + "\\cfg\\RCU" + curr + ".cfg";
FileStream file1 = new FileStream(localpath, FileMode.Open);
StreamReader reader = new StreamReader(file1);
while ((item = reader.ReadLine()) != null)
{
for (i = p; i < 100; i++)
{
for (j = 0; j < 1000; i++)
{
if (item.Contains("Signal_Sensor"))
{
sensor++;
FileBase[i, j] = "Signal_SensorA" + sensor;
break;
}
else if (item.Contains("Signal_PositionA"))
{
controlD++;
FileBase[i, j] = "Signal_PositionA" + controlD;
break;
}
else if (item.Contains("Division") && (controlD != 0))
{
FileBase[i, j] = "Division";
FileBase[i, j + 1] = Convert.ToString(CommaClear(Value));
break;
}
else if (item.Contains("LowerLimitExternal"))
{
FileBase[i, j] = "LowerLimitExternal";
FileBase[i, j + 1] = Convert.ToString(CommaClear(Value));
break;
}
else if (item.Contains("UpperLimitExternal"))
{
FileBase[i, j] = "UpperLimitExternal";
FileBase[i, j + 1] = Convert.ToString(CommaClear(Value));
break;
}
else if (item.Contains("LowerLimit"))
{
FileBase[i, j] = "LowerLimit";
FileBase[i, j + 1] = Convert.ToString(CommaClear(Value));
break;
}
else if (item.Contains("UpperLimit"))
{
FileBase[i, j] = "UpperLimit";
FileBase[i, j + 1] = Convert.ToString(CommaClear(Value));
break;
}
else if (item.Contains("LoadCell"))
{
loadcell = true;
break;
}
else if (item.Contains("PositionSensor"))
{
possensor = true;
break;
}
else if (item.Contains("EnableSensorA" + smth))
{
smth++;
FileBase[i, j] = "EnableSensorA" + smth;
FileBase[i, j + 1] = Convert.ToString(CommaClear(Value));
break;
}
else if (item.Contains("InvertSensorA"))
{
smth++;
FileBase[i, j] = "InvertSensorA" + (smth - 3);
FileBase[i, j + 1] = Convert.ToString(CommaClear(Value));
break;
}
if (smth ==6)
{
smth = 0;
break;
}
}
p = i;
break;
}
}
reader.Close();
File.Create(ReportPath);
FileStream ReportFill = new FileStream(ReportPath, FileMode.Open);
StreamReader reader1 = new StreamReader(ReportFill);
WriteArray();
reader1.Close();
Thanks in advance!

Visual studio C# Invisible Friend Game code

I've been trying how to make the couples, what I have to do is develop a program(console app) where I have to
Add players(max 30)
Mix those players between then(every name has to appear in each column once
For example:
The partner of Maria is Juan, therefore Maria has to give the gift to Juan, each person has to appear once on each side. I've tried 2 codes:
Code 1:
Console.WriteLine("Bienvenido al juego del amigo invisible!");

NPOI Excel Format not working

I have a function that is generating an Excel file using the NPOI Library. Witch for the most part is working fine just got a problem with style's they seem to function dodgy. Currently my focus is the number formats:
I would like all decimals to display as: 12.156.235,33 for example
According to the reserach on google the format that should do that should be: "#,##0.00" but the value shows up as: 12156235,33 and the cell type is set to general instead of number
It also looks like alot of people have problems with this. Hope there is a solution cos everything else I whanted to do I managed with the NPOI library and would not whant to switch now.
The procedure:
IDataFormat dataFormat;
public string GenerateExcel(ExcelData data)

After changing tabpage, the combobox crashes

I have a combobox outside my tabcontrol. In each tab control there is a datagridview full of values. In the combobox you can choose a conversion for all values. For example eV→meV.
When i am in the first tab and use the combobox there are no problems, but after i switch the tab and then wanna use the combobox the program list down however the whole combobox is full of try/catch

Accept these answer if you dont know how to post your own answer?.
Answer:
Problem fixed. The reason was the dgv.autosizemode , when i deactivate it before the conversions it runs.
for (int Spalte = 0; Spalte < Anzahl; Spalte++)
{
DGV[Spalte].AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None;
for (int i = 0; i < counter[Spalte]; i++)
{
DGV[Spalte][0, i].Value = meV[Spalte][i];
}
DGV[Spalte].AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells;
}
