Exporting database to excel file
Aug 29 2012 1:13 AM
i am exporting database to excel file.
Code as follows,
public partial class _Default : System.Web.UI.Page
{
SqlConnection con ;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
con== new SqlConnection("Server=(local);
initial catalog=Rental;Trusted_
Connection=True");
string sql = null;
string data = null;
int i = 0;
int j = 0;
Excel.Application xlapp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorksheet;
object misvalue = System.Reflection.Missing.
Value;
xlapp = new Excel.ApplicationClass();
xlWorkBook = xlapp.Workbooks.Add(misvalue);
xlWorksheet = (Excel.Worksheet)xlWorkBook.
Worksheets.get_Item(1);
//cnn = new SqlConnection(
connectionstring);
con.Open();
sql = "Select * from mis";
SqlDataAdapter da = new SqlDataAdapter(sql, con);
DataSet ds = new DataSet();
da.Fill(ds);
for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
{
for (j = 0; j <= ds.Tables[0].Columns.Count - 1; j++)
{
data = ds.Tables[0].Rows[i].
ItemArray[j].ToString();
xlWorksheet.Cells[i + 1, j + 1] = data;
}
}
MessageBox.Show("Excel file created , you can find the file
E:\\excel.
xls ");
}
private void releaseObject(object obj)
{
try
{
System.Runtime.
InteropServices.Marshal.
ReleaseComObject(obj);
obj = null;
}
catch (Exception ex)
{
obj = null;
MessageBox.Show("Exception Occured while releasing object " + ex.ToString());
}
finally
{
GC.Collect();
}
}
}
From the Above Code there is one line called
MessageBox.Show("Excel file created , you can find the file E:\\
excel
.
xls");
when click the button the message shows "Excel file created,you can find the file
E:\\
excel
.
xls.
but when i see the E folder under
excel,
the excel is not there.what is the mistake in the above code line. please help me.
