現(xiàn)在給大家介紹一種最簡(jiǎn)單的跨窗體操作
WinForm的窗體是一個(gè)類(lèi)，C#的類(lèi)是引用類(lèi)型，那么我們應(yīng)該可以將WinForm窗體類(lèi)進(jìn)行傳遞，那不就可以進(jìn)行操作了么？
效果描述： 有三個(gè)窗體然后順序分別是 (1)點(diǎn)擊第一個(gè)窗體中的按鈕彈出第二個(gè)窗體,隱藏第一個(gè)窗體 (2)第二個(gè)窗體到一定時(shí)間彈出第三個(gè)窗體 (3)點(diǎn)擊第三個(gè)窗體的按鈕關(guān)閉第三個(gè)和第二個(gè)窗體,彈出第一個(gè)窗體 |
