Export only specific column to Excel

Hello,

 

I have the following code that will export the entire DataBound DataGridView to Excel. Looking for advice on the best way to export only certain columns.

 

Here is the code that I am using to export all columns to Excel

 

try

{

Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();

excel.Visible = true;

Microsoft.Office.Interop.Excel.Workbook workbook = excel.Workbooks.Add(System.Reflection.Missing.Value);

Microsoft.Office.Interop.Excel.Worksheet sheet1 = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets[1];

int StartCol = 1;

int StartRow = 1;

int j = 0, i = 0;

//Write Headers

for (j = 0; j < dgv_preview.Columns.Count; j++)

{

Microsoft.Office.Interop.Excel.Range myRange = (Microsoft.Office.Interop.Excel.Range)sheet1.Cells[StartRow, StartCol + j];

myRange.Value2 = dgv_preview.Columns[j].HeaderText;

}

StartRow++;

//Write datagridview content

for (i = 0; i < dgv_preview.Rows.Count; i++)

{

for (j = 0; j < dgv_preview.Columns.Count; j++)

{

try

{

Microsoft.Office.Interop.Excel.Range myRange = (Microsoft.Office.Interop.Excel.Range)sheet1.Cells[StartRow + i, StartCol + j];

myRange.Value2 = dgv_preview[j, i].Value == null ? "" : dgv_preview[j, i].Value;

}

catch

{

;

}

}

}

}

catch (Exception ex)

{

MessageBox.Show(ex.ToString());

}
