㈠ 像酷狗音樂，優酷視頻這樣的桌面應用都是WinForm窗體程序嗎還是其他的什麼
是winform程序，但是他具體是用什麼開發的就不知道了，但是肯定是winform窗口程序，當然它也可能用winform窗口裡面嵌入網頁
㈡ 關於C#WinForm播放背景音樂的問題，求查看
mciSendString原來好象不支持WMA的（不確定），可能和版本有問題。
㈢ C# Winform 音樂播放器指定音頻輸出設備的問題
主要是添加引用，COM中Windows Media Player在工具箱右擊選擇「」按鈕，單擊選擇項，在"COM"組件版中選擇"Windows Media Player"，就權可以在控制項中選擇Windows Media Player控制項了，
㈣ C# 想用winform做一個播放器 想附加聲波特效 就是那個一起一伏的 隨著音樂的起伏的東西 要怎麼實現
聲音播放有控制項 隨聲波調整 要第三方控制項了
㈤ C#的winform程序如何實現mp3文件的播放啊
用API函數就行，新建個類文件把下面的代碼粘進去在調用play方法就行了(先給FileName屬性賦值)
調用方法
Test.Mp3 mp3 = new Test.Mp3();
mp3.FileName = xxx;
mp3.play();
類代碼
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace Test
{
class Mp3
{
public Mp3()
{
}
