prepend headers to my csv file - c#

I want to prepend headers to my CSV File as to let the data reflect the headings. How would I go about this without having to add it each time writing to the file? Meaning I only want the headers added once on each export. When am exporting to the same file name it should not create duplicates of the same headers. Here is my code below which writes to file:
private void button6_Click_2(object sender, EventArgs e)
{
int count_row = dataGridView1.RowCount;
int count_cell = dataGridView1.Rows[0].Cells.Count;
MessageBox.Show("Please wait while " +comboBox5.Text+ " table is being exported..");
for (int row_index = 0; row_index <= count_row - 2; row_index++)
{
for (int cell_index = 1; cell_index <= count_cell - 1; cell_index++)
{
textBox8.Text = textBox8.Text + dataGridView1.Rows[row_index].Cells[cell_index].Value.ToString() + ",";
}
textBox8.Text = textBox8.Text + "\r\n";
}
System.IO.File.WriteAllText("C:\\Users\\jdavis\\Desktop\\"+comboBox5.Text+".csv", textBox8.Text);
MessageBox.Show("Export of " +comboBox5.Text+ " table is complete!");
textBox8.Clear();
}
Updated attempt:
private void button6_Click_2(object sender, EventArgs e)
{
int count_row = dataGridView1.RowCount;
int count_cell = dataGridView1.Rows[0].Cells.Count;
MessageBox.Show("Please wait while " + comboBox5.Text + " table is being exported..");
if (!File.Exists(comboBox5.Text))
{
string rxHeader = "Code" + "," + "Description" + "," + "NDC" + "," + "Supplier Code"
+ "," + "Supplier Description" + "," + "Pack Size" + "," + "UOM" + Environment.NewLine;
for (int row_index = 0; row_index <= count_row - 2; row_index++)
{
for (int cell_index = 1; cell_index <= count_cell - 1; cell_index++)
{
textBox8.Text = textBox8.Text + dataGridView1.Rows[row_index].Cells[cell_index].Value.ToString() + ",";
}
textBox8.Text = textBox8.Text + "\r\n";
}
System.IO.File.WriteAllText("C:\\Users\\jdavis\\Desktop\\" + comboBox5.Text + ".csv", textBox8.Text);
MessageBox.Show("Export of " + comboBox5.Text + " table is complete!");
textBox8.Clear();
}
}
I really want to try and achieve it without SteamWriter, where am I going wrong?
private void button6_Click_2(object sender, EventArgs e)
{
int count_row = dataGridView1.RowCount;
int count_cell = dataGridView1.Rows[0].Cells.Count;
string path = "C:\\Users\\jdavis\\Desktop\\" + comboBox5.Text + ".csv";
string rxHeader = "Code" + "," + "Description" + "," + "NDC" + "," + "Supplier Code"
+ "," + "Supplier Description" + "," + "Pack Size" + "," + "UOM";
MessageBox.Show("Please wait while " + comboBox5.Text + " table is being exported..");
for (int row_index = 0; row_index <= count_row - 2; row_index++)
{
for (int cell_index = 1; cell_index <= count_cell - 1; cell_index++)
{
textBox8.Text = textBox8.Text + dataGridView1.Rows[row_index].Cells[cell_index].Value.ToString() + ",";
}
textBox8.Text = textBox8.Text + "\r\n";
if (!File.Exists(path))
{
System.IO.File.WriteAllText(path, rxHeader);
System.IO.File.WriteAllText(path, textBox8.Text);
}
else
{
System.IO.File.AppendAllText(path, textBox8.Text);
MessageBox.Show("Export of " + comboBox5.Text + " table is complete!");
textBox8.Clear();
}
}
}

Here is the short version that will even properly handle values that contain , and ":
dataGridView1.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableAlwaysIncludeHeaderText;
dataGridView1.RowHeadersVisible = false; // the row headers column is copied too if visible
dataGridView1.SelectAll(); // only the selected cells are used (the Windows Clipboard is not used)
DataObject dataObject = dataGridView1.GetClipboardContent(); // 4 Data Formats: Text,Csv,HTML Format,UnicodeText
File.WriteAllText("1.csv", dataObject.GetData("Csv") as string); // DataFormats.CommaSeparatedValue = "Csv"
//string html = Encoding.ASCII.GetString((dataObject.GetData("HTML Format") as MemoryStream).ToArray()); // just the HTML Clipboard Format is in a MemoryStream

This is my suggested solution.
My suggestion is to first check if the file exists or not, to then decide if you need to write the header or not.
private void DoTheWork(int fileIDtoUpdate)
{
//this is just my representation of what probably already exist in your project
string textInTheTextBox = "blah blah blah blah\nI love text\nI love code\nI love to Code\ndon't you just love to code!";
string filePath1 = #"M:\StackOverflowQuestionsAndAnswers\40726017\File1.txt";
string filePath2 = #"M:\StackOverflowQuestionsAndAnswers\40726017\File2.txt";
string filePath3 = #"M:\StackOverflowQuestionsAndAnswers\40726017\File3.txt";
string filePath4 = #"M:\StackOverflowQuestionsAndAnswers\40726017\File4.txt";
string fileToWorkWith = string.Empty;
//decide which file to work with
switch (fileIDtoUpdate)
{
case 1:
fileToWorkWith = filePath1;
break;
case 2:
fileToWorkWith = filePath2;
break;
case 3:
fileToWorkWith = filePath3;
break;
case 4:
fileToWorkWith = filePath4;
break;
default:
break;
}
//check if the file existed
bool fileExisted = File.Exists(fileToWorkWith);
using (StreamWriter sw = new StreamWriter(fileToWorkWith, true))
{
if (!fileExisted)
{
//if the file did not exist, then you need to put your header line!
sw.WriteLine("Write your Header Line here");
}
sw.WriteLine(textInTheTextBox);//down here... who cares if the file existed or not, you need to append this text to it no matter what!
}
}

Got the answer by simply editing my code with this snippet:
if (!File.Exists(path))
{
System.IO.File.WriteAllText(path, rxHeader + textBox8.Text);
}
else
{
System.IO.File.AppendAllText(path, textBox8.Text);
MessageBox.Show("Export of " + comboBox5.Text + " table is complete!");
textBox8.Clear();
}

for (int row_index = 0; row_index <= count_row - 2; row_index++)
{
textBox8.Text = textBox8.Text + "\r\n";
for (int cell_index = 1; cell_index <= count_cell - 1; cell_index++)
{
textBox8.Text = textBox8.Text + dataGridView1.Rows[row_index].Cells[cell_index].Value.ToString() + ",";
}
}
Just go to the property pannel of textBox8. Text and add column header with comma and set the textbox8 visibility to hidden.

Keep int variables values from dataReader c#

I don't have much experience with C# but I am trying to make a simple windows forms app with personal finances.
So, I have 2 dataReader (I am using the Oracle provider), and the sql (oracle table) commands that select only 2 columns from a table, only with 1 value, mainly income 1 and income2 and the sum of all values from a specific month.
the sql strings look like this:
strSQL_sel_income1 = "select DISTINCT categorie,SUM(suma) from financiar where main_categ='income' and categorie IN ('income1') and EXTRACT(month FROM data)=" + luna_income + " Group by categorie";
strSQL_sel_income2 = "select DISTINCT categorie,SUM(suma) from financiar where main_categ='income' and categorie IN ('Income2') and EXTRACT(month FROM data)=" + luna_income + " Group by categorie";
the "luna_income" value is taken from a combobox where I select a specific month.
The problem is when I try to declare an Int variable from the values I get with data reader and these variables are not kept outside the while statement... dr_income1/2 being the dataReader
if (dr_income1.HasRows)
{
while (dr_income1.Read())
{
label26.Text = dr_income1.GetString(0) + ": " + dr_income1.GetInt32(1) + "\n";
int suma_income1 = dr_incomei1.GetInt32(1);
}
}
else
{
label26.Text = "No info;
}
so, I have two similar data readers and two int variables suma_income1 and suma_income2. If I try to make a sum of them, outside the WhIle codes, I get a zero value. Where should I declare the two variables and how to keep their values?
int suma_income_total = suma_income1 + suma_income2;
label29.Text = "Income total: " + suma_income_total;
The suma_income_total is ZERO!!!
dr_income1 = cm1.ExecuteReader();
dr_income2 = cm2.ExecuteReader();
label26.Text = "";
label28.Text = "";
if (dr_income1.HasRows)
{
while (dr_income1.Read())
{
label26.Text = dr_income1.GetString(0) + ": " + dr_income1.GetInt32(1) + "\n";
int suma_income1 = dr_income1.GetInt32(1);
}
}
else
{
label26.Text = "No info";
}
if (dr_income2.HasRows)
{
while (dr_income2.Read())
{
label28.Text = dr_income2.GetString(0) + ": " + dr_income2.GetInt32(1) + "\n";
int suma_income2 = dr_income2.GetInt32(1);
}
}
else
{
label28.Text = "no info";
}
int suma_income_total = suma_income1 + suma_income2;
label29.Text = "income total: " + suma_income_total;
dr_income2.Close();
dr_income1.Close();
I put some changes in your code. It is not ideal since there are several much simple ways. But it is ok as workaround:
dr_income1 = cm1.ExecuteReader();
dr_income2 = cm2.ExecuteReader();
label26.Text = "";
label28.Text = "";
var suma_income1 =0;
var suma_income2 =0;
if (dr_income1.HasRows)
{
while (dr_income1.Read())
{
label26.Text = dr_income1.GetString(0) + ": " + dr_income1.GetInt32(1) + "\n";
suma_income1 += dr_income1.GetInt32(1);
}
}
else
{
label26.Text = "No info";
}
if (dr_income2.HasRows)
{
while (dr_income2.Read())
{
label28.Text = dr_income2.GetString(0) + ": " + dr_income2.GetInt32(1) + "\n";
suma_income2 += dr_income2.GetInt32(1);
}
}
else
{
label28.Text = "no info";
}
int suma_income_total = suma_income1 + suma_income2;
label29.Text = "income total: " + suma_income_total;
dr_income2.Close();
dr_income1.Close();

Encoding missing from reading file

Hello i'm developing a little application that download attachment from unread mails by imap and make a sevarla job on this attachment. Problem is encoding because after i have saved a, for example, txt file, when i load it again letters with accents becomes "?" I dont know why. I tried a several example around on the web (like converting directly the file from ansi to utf-8) with no result. Whe i open a file in windows it works, words are correct.
i have used either ReadAllText that StreamReader in the following example:
string contents = File.ReadAllText(AppDomain.CurrentDomain.BaseDirectory + "\\uid\\" + summary.UniqueId.ToString() + "\\" + fileName, Encoding.UTF8);
using (StreamReader reader = new StreamReader(contents, Encoding.UTF8))
as you can see in the following example if i set directly a string with an accent word, it works, from file no.
Please help me!

After searching around on the web i found a solution, here microsoft msdn
Streamreader and maybe readalltext doesn't support accent letters with UTF-8 Encoding, so changing it in UTF-7, letters are showed correctly.
Thank you for all support!

This Generates a simple excel file like this below. Object values will be inserted below the second row.
Is there a way to do the same thing, but into a template excel file? I have an excel file like the one below.
I would like the imported data to show on the left hand side of the excel file.
Also, I want to use macros that I made in the second excel file shown.

C# streamwriter create part of files

I am trying to create a hash text file. The code works, the problem is that once the streamwriter starts the process it won't stop until it is finished. I want to break up the output file into smaller parts. How do I stop the streamwriter and start a new file without starting the process over again?

I assume you're trying to get 2,000,000 items per file? You just need to restructure a little.
Right now you have:
using (StreamWriter h = new StreamWriter(hashfile))
using (StreamWriter c = new StreamWriter(charfile))
using (StreamReader sr = new StreamReader(infile))
{
string i = "";
while ((i = sr.ReadLine()) != null)
{
You need to change your code so that you open the output files later:
using (StreamReader sr = new StreamReader(infile))
{
StreamWriter h = null;
StreamWriter c = null;
try
{
h = new StreamWriter(...);
c = new StreamWriter(...);
string i = "";
while ((i = sr.ReadLine()) != null)
{
// output line here
// and increment line counter.
++line;
if (line > 2000000)
{
// Close the output files and open new ones
h.Close();
c.Close();
h = new StreamWriter(...);
c = new StreamWriter(...);
line = 1;
}
}
}
finally
{
if (h != null) h.Close();
if (c != null) c.Close();
}
}
