dgv에서 선택한 행만 Excel로 내보내는 방법?

Question

누구든지 dgv에서 선택한 행만 excle으로 내보내는 것을 도와 줄 수 있습니까? 가져 오기 및 검색 및 내보내기를위한 코드 아래에 있습니다. 그러나 선택한 행만 내보내는 이유가 확실하지 않습니다.

Answer 1

for (int i = 0; i < dataGridView1.SelectedRows.Count - 1; i++) 
{ 
    for (int j = 0; j < dataGridView1.Columns.Count; j++) 
    { 
     worksheet.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString(); 
    } 
} 

는 귀하의 루프가 선택 행을 열거하도록 구성,하지만 당신은 모든 행에서 값을 가지고있다. .Rows[i]을 .SelectedRows[i]으로 변경하십시오.
