最近看來是跟聲音干上了啊!
音頻轉換的第二種方法,這種方法相對第一種來說,要簡單的多!
首先,你得下載個“ffmpeg.exe” 插件,然後把它放到你的項目中,如下圖:

程序中會調用該文件,以助於轉換音頻格式!
上代碼:
using System;
using System.Threading;
using System.IO;
using System.Diagnostics;
using System.Security;
public partial class cowala_201512Chritmas_amrtest : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
changedPlay.Visible = false;
}
}
protected void Ffmpeg_Click(object sender, EventArgs e)
{
if (AmrFileUp.HasFile)
{
string key = AmrFileUp.FileName;
string savepath = Server.MapPath("~/upload/amr/") + key;
AmrFileUp.SaveAs(savepath);
string mp3SavePth = Server.MapPath("~/upload/mp3/") + key.Split('.')[0].ToString() + ".mp3";
if (!string.IsNullOrEmpty(ConvertToMp3(savepath, mp3SavePth)))
{
changedPlay.Visible = true;
changedPlay.Attributes.Add("src", "upload/mp3/" + key.Split('.')[0].ToString() + ".mp3");
Response.Write("<script>alert('轉換成功!');</script>");
}
}
}
public string ConvertToMp3(string pathBefore, string pathLater)
{
string c = Server.MapPath("/ffmpeg/") + @"ffmpeg.exe -i " + pathBefore + " " + pathLater;
string str = RunCmd(c);
return str;
}
/// <summary>
/// 執行Cmd命令
/// </summary>
private string RunCmd(string c)
{
try
{
ProcessStartInfo info = new ProcessStartInfo("cmd.exe");
info.RedirectStandardOutput = false;
info.UseShellExecute = false;
Process p = Process.Start(info);
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.Start();
p.StandardInput.WriteLine(c);
p.StandardInput.AutoFlush = true;
Thread.Sleep(1000);
p.StandardInput.WriteLine("exit");
p.WaitForExit();
string outStr = p.StandardOutput.ReadToEnd();
p.Close();
return outStr;
}
catch (Exception ex)
{
return "error" + ex.Message;
}
}
}
接著來張效果圖:

好了,就這麼簡單,不要不敢不相信你的眼睛,其實就是這麼簡單!
最後,來個問題:你們解完手後,擦時,習慣用左手還是右手?
