一、音頻文件上傳和播放
在網(wǎng)上找到一個(gè)名叫AspNetPager的第三方控件，將AspNetPager.dll文件引用到項(xiàng)目的Bin中。在網(wǎng)頁(yè)中可直接調(diào)用。引用命名空間 using Telerik.WebControls;
>>上傳

復(fù)制代碼代碼如下:

 
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;//獲取文件原來(lái)的名字 
string namelast = namefile.Substring(namefile.LastIndexOf("."));//獲取文件的后綴名,LastIndexOf()-返回括號(hào)內(nèi)字符的所在位置 
string FilePath = System.AppDomain.CurrentDomain.BaseDirectory + @"SaveFilePath/MBmusic/";//文件上傳的路徑 
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 = "http://www.cnblogs.com/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 = "http://www.cnblogs.com/SaveFilePath/MBmusic/" + name; 
mf.MF_Path = mv; 
//mf.MF_Path = mv; 
} 
if (RemainByteSize >= Filesizes) 
{ 
try 
{ 
//將數(shù)據(jù)插入數(shù)據(jù)庫(kù) 
if (addnum > 0 && udpsize > 0) 
{ 
//Response.Write("<script>alert('上傳成功!!')</script>"); 
//Bind(); 
} 
else 
{ 
Response.Write("<script>alert('上傳失敗!!')</script>"); 
return; 
} 
num++; 
} 
catch { } 
} 
else 
{ 
Response.Write("<script>alert('空間不足，請(qǐng)申請(qǐng)空間!!')</script>"); 
return; 
} 
} 
else 
{ 
Response.Write("<script>alert('上傳文件格式錯(cuò)誤! 文件格式為mp3,wma,wav.rm的視頻!')</script>"); 
return; 
} 
} 
else 
{ 
Response.Write("<script>alert('請(qǐng)選擇上傳的文件')</script>"); 
return; 
} 
} 
} 

>>播放
1、在播放頁(yè)面添加控件Literal1 控件
2、在頁(yè)面后臺(tái)添加調(diào)用音頻播放器代碼

復(fù)制代碼代碼如下:

 
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、調(diào)用GetFlashText()方法

復(fù)制代碼代碼如下:

 
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調(diào)用方法播放音頻 
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(); 
} 
} 
}
