用c#如何读取别人机子上的视频文件并保存?
------解决方案--------------------我现在也正在做一个同学录.要考虑歌曲的上传和播放.主要采取二进制的办法. 
 HttpPostedFile UpFile =this.File1.PostedFile; //HttpPostedFile对象,用于读取图象文件属性  
 			FileLength = UpFile.ContentLength; //记录文件长度  
 			try  
 			{  
 				if (FileLength == 0)  
 				{ //文件长度为零时  
 					this.lblInfo.Text =  " <b> 请你选择你要上传的文件 </b>  ";  
 				}  
 				else  
 				{   		 
 					Byte[] FileByteArray = new Byte[FileLength]; //图象文件临时储存Byte数组  
 					Stream StreamObject = UpFile.InputStream; //建立数据流对像  
 					//读取图象文件数据,FileByteArray为数据储存体,0为数据指针位置、FileLnegth为数据长度  
 					StreamObject.Read(FileByteArray,0,FileLength);  
 					//建立SQL Server链接  
 					SqlConnection Con = new SqlConnection( "uid=sa;pwd=19830517;initial catalog=SWFCXYL;data source=. ");  
 					//String SqlCmd =  "INSERT INTO ImageStore (ImageData, ImageContentType, ImageDescription, ImageSize) VALUES (@Image, @ContentType, @ImageDescription, @ImageSize) ";  
 					string SqlCmd= "insert into song (username,accept,songname,songaddr,Content,songtype,songsize) values(@username,@accept,@songname,@songaddr,@Content,@songtype,@songsize) ";   
 					SqlCommand CmdObj = new SqlCommand(SqlCmd, Con);  
 					CmdObj.Parameters .Add ( "@username ",SqlDbType.VarChar ,20).Value=this.lblUserName.Text ; 
 					CmdObj.Parameters .Add ( "@accept ",SqlDbType.VarChar ,20).Value=this.txtAcceptName.Text ; 
 					CmdObj.Parameters .Add ( "@songname ",SqlDbType.VarChar ,50).Value=this.txtSongName.Text ; 
 					CmdObj.Parameters.Add( "@songaddr ",SqlDbType.Binary, FileLength).Value = FileByteArray;  
 					CmdObj.Parameters .Add ( "@Content ",SqlDbType.VarChar ,255).Value=this.txtRemark.Text ;   
 					CmdObj.Parameters.Add( "@songtype ", SqlDbType.VarChar,50).Value = UpFile.ContentType; //记录文件类型  
 					//把其它单表数据记录上传   					  
 					//记录文件长度,读取时使用  
 					CmdObj.Parameters.Add( "@songsize ", SqlDbType.Int).Value = UpFile.ContentLength;  
 					Con.Open (); 
 					CmdObj.ExecuteNonQuery();  
 					Con.Close();  
 					this.lblInfo.Text =  " <p>  <b> OK!你已经成功上传你的图像文件 </b>  ";//提示上传成功      
 				}  
 			}  
 			catch (Exception ex)  
 			{  
 				this.lblInfo.Text = ex.Message.ToString();  
 			}
