need a quicker way to select data and paste it in an excel sheet

It took me a while to just find a way to select data from my database and then paste it in an excel spreadsheet. Now that I've found it, it runs dirt slow. Like I said before, I've looked at a lot of different ways to accomplish this but have not been able to correctly implement any of them except for this. I'm not married to this option but it is the only one I could get to work. Could someone help me out by suggesting a quicker way to accomplish this simple task? Please see my code below.
Record850 rec850 = new Record850();
List<Record850> lst850records = new List<Record850>();
//SqlConnection connStr = new SqlConnection("Server = 172.18.211.76; Database = Processstage; User Id = brendon.davies; Password = mypassword;");
SqlConnection conn = new SqlConnection("Server = 172.18.211.76; Database = Processstage; User Id = brendon.davies; Password = mypassword;");
//SqlConnection sqlConnection1 = new SqlConnection(conn);
SqlCommand cmd = new SqlCommand();
SqlDataReader reader;
cmd.CommandText = Select_850;
cmd.CommandType = CommandType.Text;
cmd.Connection = conn;
conn.Open();
Record850 reco850 = new Record850();
string strComplete = "";
reader = cmd.ExecuteReader();
while (reader.Read())
{
try
{
reco850.OrgName = reader.GetString(0);
reco850.WholeSalerAccountDivisionCode = reader.GetString(1);
reco850.File_Process_Name = reader.GetString(2);
reco850.Pur_Ord_Num_BEG03 = reader.GetString(3);
reco850.File_Process_ID = reader.GetInt64(4);
reco850.CECode = reader.GetString(5);
reco850.CEName = reader.GetString(6);
reco850.Modified_Date = reader.GetDateTime(7);
lst850records.Add(reco850);
reco850 = new Record850();
}
catch(Exception e)
{
Console.WriteLine(e.ToString());
}
}
conn.Close();
eWorkSheet = (Excel.Worksheet)oSheets.get_Item("850_Template");
eWorkSheet.Activate();
int int850counter = 0;
int int850RowCounter = 3;
foreach (Record850 r850 in lst850records)
{
strComplete = lst850records[int850counter].OrgName + "\t" +
lst850records[int850counter].WholeSalerAccountDivisionCode + "\t" +
lst850records[int850counter].File_Process_Name + "\t" +
lst850records[int850counter].Pur_Ord_Num_BEG03 + "\t" +
lst850records[int850counter].File_Process_ID + "\t" +
lst850records[int850counter].CECode + "\t" +
lst850records[int850counter].CEName+ "\t" +
lst850records[int850counter].Modified_Date;
CR = (Excel.Range)eWorkSheet.Cells[int850RowCounter,3];
Clipboard.SetText(strComplete);
CR.Select();
eWorkSheet.Paste(CR, false);
Clipboard.Clear();
int850RowCounter++;
int850counter++;
strComplete = ""
}

Here's an answer that also runs quickly, just about the same as the use of EPPlus above. Do not attempt the cell by cell approach (commented out below) as that indeed runs at a snail's pace by comparison.
[STAThread]
static void Main(string[] args)

Excel.Application xl = null;
try {
xl = new Excel.Application();
xl.ScreenUpdating = false;

var wb = xl.Workbooks.Open(SOURCE_PATH);
var ws = (Microsoft.Office.Interop.Excel.Worksheet)wb.Sheets.Item["850_Template"];
StringBuilder sb = new StringBuilder();

//a1.Offset[row, 7].Value = (DateTime)dr["Modified_Date"];
//row++;
}
}
}
cn.Close();
}
Clipboard.SetText(sb.ToString(),
TextDataFormat.Text);
var rng = ws.Range["A3", Missing.Value];
rng.Select();
ws.Paste(rng, Missing.Value);
Clipboard.Clear();
wb.Save();
wb.Close();

} catch (Exception ex) {
Console.WriteLine(ex.Message);
if (xl != null) {

}

Here's an alternative that uses the EPPlus approach, much faster.
try {
var app = new ExcelPackage(new FileInfo(SOURCE_PATH));
var ws = app.Workbook.Worksheets["850_Template"];
int row = 3;
using (SqlConnection cn = new SqlConnection(CN_STR)) {
cn.Open();
using (SqlCommand cmd = new SqlCommand(SQL, cn)) {
cmd.CommandType = CommandType.Text;
using (SqlDataReader dr = cmd.ExecuteReader()) {
while (dr.Read())
{
ws.SetValue(row, 1, (string) dr["OrgName"]);
ws.SetValue(row, 2, (string) dr["WholeSalerAccountDivisionCode"]);
ws.SetValue(row, 3, (string) dr["File_Process_Name"]);
ws.SetValue(row, 4, (string) dr["Pur_Ord_Num_BEG03"]);
ws.SetValue(row, 5, (long) dr["File_Process_ID"]);
ws.SetValue(row, 6, (string) dr["CECode"]);
ws.SetValue(row, 7, (string) dr["CEName"]);
ws.SetValue(row, 8, (DateTime) dr["Modified_Date"]);
row++;
}
}
}
cn.Close();
}
app.Save();
} catch (Exception ex) {
Console.WriteLine(ex.Message);

how to delete first field and all values of this field in .CSV file using C#

I want to load .csv file and then import to SQl database. But before I do that, I want to do something to delete first field (in header) and also all values of this field.
this below is the example of my .csv file :
> TableId|PERIODE|DATEBALANCEASOF|ACCCODE|CUSTNAME|CUSTGROUP|
> TB_001|201501|2015-01-01|11-0001|DYNAMIC EXPRESS|11|
> TB_001|201501|2015-01-01|11-0002|DYNAMIC EXPRESS|12|
> TB_001|201501|2015-01-01|11-0003|DYNAMIC EXPRESS|13|
> TB_001|201501|2015-01-01|11-0004|DYNAMIC EXPRESS|14|
before I import that .csv file, I need my .csv file willbe like this below :
PERIODE|DATEBALANCEASOF|ACCCODE|CUSTNAME|CUSTGROUP|
201501|2015-01-01|11-0001|DYNAMIC EXPRESS|11|
201501|2015-01-01|11-0002|DYNAMIC EXPRESS|12|
201501|2015-01-01|11-0003|DYNAMIC EXPRESS|13|
201501|2015-01-01|11-0004|DYNAMIC EXPRESS|14|
this below is my code :

string[] files = Directory.GetFiles(pathLocalSuccess);
if (files == null)
{
MessageBox.Show("Files not found");
}
foreach (string file in files)
{
FileInfo fileInf = new FileInfo(file);
string filename = fileInf.Name;
StreamReader reader = new StreamReader(file);
string line = reader.ReadLine();
string[] value = line.Split('|');

con.Close();
reader.Close();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
Please help me to resolve this problem..

Thanks for everyone who respons my question,
Actually I already solve this problem using a little editing in my code
this below is my code and works for me :
public void readCSVAutomatic(string pathLocalSuccess, string pathHistory, string pathLogFolderSuccess, string pathErrorLog, string modul)
{
try
{
string[] files = Directory.GetFiles(pathLocalSuccess);
foreach (string file in files)
{
FileInfo fileInf = new FileInfo(file);
string filename = fileInf.Name;
StreamReader reader = new StreamReader(file);
string line = reader.ReadLine();
string[] value = line.Split('|');
DataTable dt = new DataTable();
DataRow row;
foreach (string dc in value)
{
dt.Columns.Add(new DataColumn(dc));
}
while (!reader.EndOfStream)
{
//value = value.
value = reader.ReadLine().Split('|');
if (value.Length == dt.Columns.Count)
{
row = dt.NewRow();
row.ItemArray = value;
dt.Rows.Add(row);
}
}
string xTableName = dt.Rows[0].ItemArray[0].ToString();
string xPeriode = dt.Rows[0].ItemArray[1].ToString();
dt.Columns.RemoveAt(0);
SqlConnection con = new SqlConnection();
con.ConnectionString = #"Data Source=" + serverDB + "; Initial Catalog=" + DB + "; Trusted_Connection=" + trustedConnection + "; user=" + UserDB + "; password=" + PassDB + "";
con.Open();
SqlCommand com = con.CreateCommand();
string strDelete = "DELETE FROM " + xTableName + " WHERE PERIODE='" + xPeriode + "'";
com.CommandText = strDelete;
com.Connection = con;
com.ExecuteNonQuery();
SqlBulkCopy bc = new SqlBulkCopy(con.ConnectionString, SqlBulkCopyOptions.TableLock);
bc.DestinationTableName = xTableName;
bc.BatchSize = dt.Rows.Count;
bc.WriteToServer(dt);
bc.Close();
con.Close();
reader.Close();
moveFileAfterImported(pathLocalSuccess, filename, pathHistory);
createLogCSVSuccessImported(pathLogFolderSuccess, "File Imported","Message");
}
}
catch(Exception ex)
{
createErrorLogImportCSV(pathErrorLog, "ErrorImportCSV", ex.ToString());
}
}

This seems to do the job for me:
First start by reading in all the files:
var datatables =
Directory
.GetFiles(pathLocalSuccess)
.Select(file => File.ReadAllLines(file).Select(x => x.Split('|')).ToArray())
.Select(lines => new
{
headers = lines[0].Skip(1).ToArray(),
lines = lines.Skip(1).Select(l => l.Skip(1).ToArray()).ToArray(),
})
.Select(x =>
{
var dt = new DataTable();
foreach (var dc in x.headers)
{
dt.Columns.Add(new DataColumn(dc));
}
foreach (var line in x.lines.Skip(1).Where(y => y.Length == x.headers.Length))
{
var row = dt.NewRow();
row.ItemArray = line;
dt.Rows.Add(row);
}
return dt;
})
.ToArray();
Then it's a simple matter of loading all the data. This code only opens the connection once. It should be quite fast.
if (!datatables.Any())
{
MessageBox.Show("Files not found");
}
else
{
using (var con = new SqlConnection())
{
con.ConnectionString = #"server=" + serverDB + "; database=" + DB + "; Trusted_Connection=" + trustedConnection + "; user=" + UserDB + "; password=" + PassDB + "";
foreach (var dt in datatables)
{
var bc = new SqlBulkCopy(con.ConnectionString, SqlBulkCopyOptions.TableLock);
bc.DestinationTableName = "ACC_004";
bc.BatchSize = dt.Rows.Count;
bc.WriteToServer(dt);
bc.Close();
}
con.Close();
}
}
The important part for skipping the first field is found in this code:
.Select(lines => new
{
headers = lines[0].Skip(1).ToArray(),
lines = lines.Skip(1).Select(l => l.Skip(1).ToArray()).ToArray(),
})

c# multiple chart error

I want to create a column chart in c#.
this is the code that i uset for that:
private void Vizualizare_profil()
{
myConn = new MySqlConnection(myConnection);
MySqlCommand selectCommand = new MySqlCommand("SELECT * FROM `gomoku`.`informatii` WHERE `id_utilizator` = '" + id_client.ToString() + "';", myConn);
MySqlDataAdapter dataAdap = new MySqlDataAdapter(selectCommand);
DataSet ds = new DataSet();
myConn.Open();
dataAdap.Fill(ds);
myConn.Close();
DataTable dt = new DataTable();
dt.Columns.Add("Nume");
dt.Columns.Add("Meciuri castigate");
dt.Columns.Add("Meciuri pierdute");
dt.Columns.Add("Meciuri remize");
if (ds.Tables[0].Rows.Count != 0)
{
label28.Text = Username;
label29.Text = ds.Tables[0].Rows[0]["nume"].ToString();
label30.Text = ds.Tables[0].Rows[0]["prenume"].ToString();
label31.Text = ds.Tables[0].Rows[0]["varsta"].ToString();
label32.Text = ds.Tables[0].Rows[0]["adresa_email"].ToString();
dt.Rows.Clear();
dt.Rows.Add("Meciuri castigate " + Convert.ToString(ds.Tables[0].Rows[0]["meciuri_castigate"]), ds.Tables[0].Rows[0]["meciuri_castigate"], 0 , 0);
dt.Rows.Add("Meciuri pierdute " + Convert.ToString(ds.Tables[0].Rows[0]["meciuri_pierdute"]), 0, ds.Tables[0].Rows[0]["meciuri_pierdute"], 0);
dt.Rows.Add("Meciuri remize " + Convert.ToString(ds.Tables[0].Rows[0]["meciuri_remiza"]), 0, 0,ds.Tables[0].Rows[0]["meciuri_remiza"]);
chart1.DataSource = dt;
chart1.Series[0].XValueMember = "Nume";
chart1.Series[0].YValueMembers = "Meciuri castigate";
chart1.Series[1].XValueMember = "Nume";
chart1.Series[1].YValueMembers = "Meciuri pierdute";
chart1.Series[2].XValueMember = "Nume";
chart1.Series[2].YValueMembers = "Meciuri remize";
}
else
MessageBox.Show("Database error!");
}
It creates perfect the first chart but if this method is called again it shows the same data.
What is the problem and what can by done?

Loss of Data after printing my crystal report via PrintToPrinter

after printing the document using PrintToPrinter all data is lost, dont know why ????
this code had one more problem, I hve rectified the problem by adding :
rpt.SetDatabaseLogon("u","p");
and now I have empty document printed.
this is my code:

THE ANSWER:
I was using Select Expert Record in the crystal report , I removed all formula in Select Expert and it worked .... :)
