asp.net - open file save popup using streamwriter
0
Below code works fine and export the results in file mentioned on D drive. How can we change this so that it opens POPUP and ask where to save the file
protected void Button1_Click(object sender, EventArgs e)
{
using (StreamWriter writer = new StreamWriter("D:\dump.csv"))
{
WriteDataTable(dt, writer, true);
}
}
public static void WriteDataTable(DataTable sourceTable, TextWriter writer, bool includeHeaders)
{
if (includeHeaders)
{
IEnumerable<String> headerValues = sourceTable.Columns
.OfType<DataColumn>()
.Select(column => QuoteValue(column.ColumnName));
writer.WriteLine(String.Join(",", headerValues));
}
IEnumerable<String> items = null;
foreach (DataRow row in sourceTable.Rows)
{
items = row.ItemArray.Select(o => QuoteValue(o?.ToString() ?? String.Empty));
writer.WriteLine(String.Join(",", items));
}
writer.Flush();
}
private static string QuoteValue(string value)
{
return String.Concat(""",
value.Replace(""", """"), """);
}
