Asp.Net音频文件上传和播放

一、音频文件上传和播放

在网上找到一个名叫AspNetPager的第三方控件，将AspNetPager.dll文件引用到项目的Bin中。在网页中可直接调用。引用命名空间 using Telerik.WebControls;

>>上传

protected void Button1_Click(object sender, EventArgs e)

{

foreach (UploadedFile file in RadUploadContext.Current.UploadedFiles)

{

if (file.FileName != null && file.FileName != "")

{

string strTime = memberid.ToString() + "-" + DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Millisecond.ToString();

string namefile = file.FileName;//获取文件原来的名字

string namelast = namefile.Substring(namefile.LastIndexOf("."));//获取文件的后缀名,LastIndexOf()-返回括号内字符的所在位置

string FilePath = System.AppDomain.CurrentDomain.BaseDirectory + @"SaveFilePath/MBmusic/";//文件上传的路径

System.IO.FileInfo fi = new System.IO.FileInfo(file.FileName);

if (fi.Extension.ToLower() == ".mp3" || fi.Extension.ToLower() == ".wma" || fi.Extension.ToLower() == ".rm" || fi.Extension.ToLower() == ".wav")

{

string name = strTime + namelast;//文件最后保存的名字

mv = "../../SaveFilePath/MBmusic/" + name;

Filesizes = int.Parse(file.ContentLength.ToString());

string path = FilePath + name;

if (File.Exists(path) == false)

{

file.SaveAs(FilePath + name);

mf.MF_Path = mv;

//mf.MF_Path = mv;

}

else if (File.Exists(path) == true)

{

name = strTime + "(" + tt + ")" + namelast;

file.SaveAs(FilePath + name);

mv = "../../SaveFilePath/MBmusic/" + name;

mf.MF_Path = mv;

//mf.MF_Path = mv;

}

if (RemainByteSize >= Filesizes)

{

try

{

//将数据插入数据库

if (addnum > 0 && udpsize > 0)

{

//Response.Write("<script>alert('上传成功!!')</script>");

//Bind();

}

else

{

Response.Write("<script>alert('上传失败!!')</script>");

return;

}

num++;

}

catch { }

}

else

{

Response.Write("<script>alert('空间不足，请申请空间!!')</script>");

return;

}

}

else

{

Response.Write("<script>alert('上传文件格式错误! 文件格式为mp3,wma,wav.rm的视频!')</script>");

return;

}

}

else

{

Response.Write("<script>alert('请选择上传的文件')</script>");

return;

}

}

}

>>播放

1、在播放页面添加控件Literal1 控件

2、在页面后台添加调用音频播放器代码

public static string GetFlashText(string url)

{

string str = @"<object id='MediaPlayer' classid='clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6' height='62' width='406'>

<param name='rate' value='1' />

<param name='balance' value='0' />

<param name='currentPosition' value='0' />

<param name='defaultFrame' value='' />

<param name='playCount' value='1' />

<param name='autoStart' value='-1' />

<param name='currentMarker' value='0' />

<param name='invokeURLs' value='-1' />

<param name='baseURL' value='' />

<param name='volume' value='2' />

<param name='mute' value='0' />

<param name='uiMode' value='full' />

<param name='stretchToFit' value='0' />

<param name='windowlessVideo' value='0' />

<param name='enabled' value='-1' />

<param name='enableContextMenu' value='0' />

<param name='fullScreen' value='0' />

<param name='SAMIStyle' value='' />

<param name='SAMILang' value='' />

<param name='SAMIFilename' value='' />

<param name='captioningID' value='' />

<param name='enableErrorDialogs' value='0' />

<param name='_cx' value='10742' />

<param name='_cy' value='1799' />

<param name='URL' value='"+url+"'/></object>";

return str;

}

3、调用GetFlashText()方法

public void BindMusic()

{

if (mfid != 0)

{

DataSet dst = mf.Search(mfid);

if (dst != null && dst.Tables[0].Rows.Count > 0)

{

string url = dst.Tables[0].Rows[0]["MF_Path"].ToString();

string[] strs = url.Split(new char[] { '/' });

string mvname = strs[strs.Length - 1];

string url1 = "SaveFilePath/MBmv/" + mvname;

Literal1.Text = GetFlashText(url);//Literal1调用方法播放音频

Label1.Text = dst.Tables[0].Rows[0]["MF_FileName"].ToString();

//txt_FileName.Text = dst.Tables[0].Rows[0]["MF_FileName"].ToString();

//txt_introduction.Text = dst.Tables[0].Rows[0]["MF_Introduction"].ToString();

}

}

}
