注釈

このメソッドを呼び出すことは有効な 1 回、ListViewを格納しているとFormが構築済みで、ListView列ヘッダーと列は項目が入力されます。Calling this method is only effective once the ListView and containing Form have been constructed, and the ListView column headers and columns are populated with items. 新しい項目を追加する場合、 ListView、サイズしない限り、列が変更されないAutoResizeColumnsが再度呼び出されます。If new items are added to the ListView, the columns will not resize unless AutoResizeColumns is called again.
