using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("请输入要打开的文件");
string filePath = Console.ReadLine();
Console.WriteLine("请输入文件名");
string fileName = Console.ReadLine();

baseFile bf = GetFile(filePath, fileName);
if(bf != null){
bf.OpenFile();
}
Console.ReadKey();
}

static baseFile GetFile(string filePath, string fileName)
{
baseFile bf = null;
string strextension = Path.GetExtension(fileName);
switch (strextension)
{
//amr
case ".amr":
bf = new TxtFile(filePath, fileName);
break;
case ".html":
bf = new TxtFile(filePath, fileName);
break;
case ".avi":
bf = new TxtFile(filePath, fileName);
break;

}
return bf;
}
}
class baseFile
{
//字段.属性.构造函数.函数.索引器
private string _filePath;

public string FilePath
{
get { return _filePath; }
set { _filePath = value; }
}

public string FileName { get; set; }

public baseFile(string filePath,string fileName) {
this.FileName = fileName;
this.FilePath = filePath;
}

//打开函数
public void OpenFile()
{
ProcessStartInfo psi = new ProcessStartInfo(this.FilePath+"\\"+this.FileName);
Process pro = new Process();
pro.StartInfo= psi;
pro.Start();
}
}

class TxtFile : baseFile
{
public TxtFile(string filePath , string fileName):base(filePath,fileName) {

}

}

class MP4File : baseFile
{
public MP4File(string filePath, string fileName) : base(filePath, fileName) { }

}
}
