在DataGridView控件中获取选定的列

使用SelectedColumns属性.若要使用户能够选择列，必须将SelectionMode属性设置为FullColumnSelect或ColumnHeaderSelect.
C#

To get the selected columns in a DataGridView control

Use the SelectedColumns property. To enable users to select columns, you must set the SelectionMode property to FullColumnSelect or ColumnHeaderSelect.
C#

private void selectedColumnsButton_Click(object sender, System.EventArgs e)
  {
      Int32 selectedColumnCount = dataGridView1.Columns
          .GetColumnCount(DataGridViewElementStates.Selected);
      if (selectedColumnCount > 0)
      {
          System.Text.StringBuilder sb = new System.Text.StringBuilder();

          for (int i = 0; i < selectedColumnCount; i++)
          {
              sb.Append("Column: ");
              sb.Append(dataGridView1.SelectedColumns[i].Index
                  .ToString());
              sb.Append(Environment.NewLine);
          }

          sb.Append("Total: " + selectedColumnCount.ToString());
          MessageBox.Show(sb.ToString(), "Selected Columns");
      }
  }
