基於C#的音樂播放器主Form完成代碼。本站提示廣大學習愛好者：（基於C#的音樂播放器主Form完成代碼）文章只能為提供參考，不一定能成為您想要的結果。以下是基於C#的音樂播放器主Form完成代碼正文
本文所述為一個由C#編寫的音樂播放器的主Form代碼，外面有一些小技能照樣不錯的，現同享給年夜家參考一下。外面有播放器配景設置、線程界說、挪用讀取文件目次辦法、播放時光計數器、設置LV配景、獲得播放歌曲、播放按鈕，切換播放or暫停、切換歌曲到下一首，挪用切歌辦法、顯示播放列表、歌詞局中、播放窗體最小化隱蔽到托盤設置、進度條轉動模塊、從歌曲列表中刪除文件等等功效。且各個功效模板均備有較為具體的正文，便於年夜家浏覽懂得。
