SQL Query to Excel in C# using Epplus

Question

I have been really struggling with this issue. I am trying to write a strings and column names from a sql query to an excel document. But I only have rows written. How do i fix the code to write all lines and columns?

 var Template = new FileInfo(@"C:\Temp\XLS\New.xlsx"); var xlPackage = new ExcelPackage(Template); var wsCards = xlPackage.Workbook.Worksheets.Add(NAME_WORKSHEET); using (SqlConnection sqlConn = new SqlConnection(ConnectionString)) { sqlConn.Open(); using (SqlCommand command = new SqlCommand(SQL_WORKSHEET, sqlConn)) { var reader = command.ExecuteReader(); int row = 1; DataTable schemaTable = reader.GetSchemaTable(); foreach (DataRow rw in schemaTable.Rows) { foreach (DataColumn column in schemaTable.Columns) { if (column.ColumnName == "ColumnName") { wsCards.Cells["A1"].Value = rw[column]; } } } while (reader.Read()) { row++; for (int col = 1; col <= reader.FieldCount; col++) { wsCards.Cells[row, col].Value = reader.GetValue(col - 1); } } xlPackage.SaveAs(Template); xlPackage.Dispose(); } }

 var Template = new FileInfo(@"C:\Temp\XLS\New.xlsx"); var xlPackage = new ExcelPackage(Template); var wsCards = xlPackage.Workbook.Worksheets.Add(NAME_WORKSHEET); using (SqlConnection sqlConn = new SqlConnection(ConnectionString)) { sqlConn.Open(); using (SqlCommand command = new SqlCommand(SQL_WORKSHEET, sqlConn)) { var reader = command.ExecuteReader(); int row = 1,col=1; DataTable schemaTable = reader.GetSchemaTable(); //foreach (DataRow rw in schemaTable.Rows) //{ // Write the headers to the first row foreach (DataColumn column in schemaTable.Columns) { // Condition Will only be required if you want to write // specific column names //if (column.ColumnName == "ColumnName") //{ wsCards.Cells[1,col].Value = rw[column].ColumnName; col++; //} } //} while (reader.Read()) { row++; for ( col = 1; col <= reader.FieldCount; col++) { wsCards.Cells[row, col].Value = reader.GetValue(col - 1); } } xlPackage.SaveAs(Template); xlPackage.Dispose(); } }

This code will write the headers from the schema on the first row of the excel sheet
