推荐答案

试试这个

try this

private void button1_Click(object sender, EventArgs e)
       {
           List<string> lstCheckedEmails = new List<string>();
           foreach (var item in checkedListBox1.CheckedItems)
           {
               string email = item.ToString();
               lstCheckedEmails.Add(email);
           }


           foreach (DataGridViewRow row in dataGridView1.Rows)
           {
               string email = row.Cells["EmailColumnName"].ToString();
               if (lstCheckedEmails.Contains(email)) {
                   // read all the necessary columns from this the row object
                   string pass = row.Cells["PasswordColumnName"].ToString();
               }
           }
       }
