Asp.Net 音频文件上传和播放代码
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 复制代码 代码如下: 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;//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 = "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 { //将数据插入数据库 if (addnum > 0 && udpsize > 0) { //Response.Write(""); //Bind(); } else { Response.Write(""); return; } num++; } catch { } } else { Response.Write(""); return; } } else { Response.Write(""); return; } } else { Response.Write(""); 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 复制代码 代码如下: public static string GetFlashText(string url) { string str = @""; return str; } 3、调用GetFlashText()方法 复制代码 代码如下: 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(); } } }
