How to export datagrid to cvs file on WPF

Question

StreamWriter sw = new StreamWriter("c:\\gridview.csv");

// now add the gridview header in csv file suffix with "," delimeter except last one

for (int i = 0; i < grid.Columns.Count; i++)

{

sw.Write(grid.Columns[i].Header.ToString());

if (i != grid.Columns.Count)

{

sw.Write(",");

}

}

// add new line

sw.Write(sw.NewLine);

// iterate through all the rows within the gridview

foreach (GridView dr in grid.SetValue(grid.Rows.Count)  // grid.Rows does not work 

{

// iterate through all colums of specific row

for (int i = 0; i < GridView1.Columns.Count; i++)

{

// write particular cell to csv file

sw.Write(dr.Cells[i].Text);

if (i != GridView1.Columns.Count)

{

sw.Write(",");

}

}

// write new line

sw.Write(sw.NewLine);

}

// flush from the buffers.

sw.Flush();

// closes the file

sw.Close();
