在程序里面（服务器端）调用Winrar压缩文件的方法？另寻求一条语句转换的方法。vb.net到C#。

 1case("zip"):   // 压缩
 2    string[] zip_tmp = this.name1.Value.Split(new char[]{'*'});
 3    string zip_tmp1= zip_tmp[zip_tmp.Length-1];
 4    if(this.CheckName(zip_tmp1))     //检测文件命名的合法性
 5    {
 6        string zip_tmp2=zip_tmp1.Replace(".zip","");
 7
 8        //移除“.zip”后缀，并防止名称重复
 9
10        this.NameExisted(1,ServerDir+@"personal\"+zip_tmp2+".zip",out zip_tmp2);
11        StreamWriter zip_sr =File.CreateText(ServerDir+"list.dat");
12        zip_sr.Write("");
13        zip_sr.Close();
14        for(int m =0;m<zip_tmp.Length-1;m++)
15        {
16            //以系统默认的 ANSI 编码创建压缩文件列表
17
18            StreamWriter zip_sw2 =new StreamWriter(ServerDir+"list.dat",true,System.Text.Encoding.Default);   
19            zip_sw2.WriteLine(ServerDir+zip_tmp[m]);
20            zip_sw2.Close();
21        }
22        System.Diagnostics.Process Process1=new System.Diagnostics.Process();
23        Process1.StartInfo.FileName=ServerDir+"Winrar.exe";
24        Process1.StartInfo.Arguments=" a  -ep1 -inul -y "+zip_tmp2+@" @"+ServerDir+"list.dat";
25        Process1.Start();    //进行压缩
26        while(!Process1.HasExited)          //等待压缩的完成
27        {
28        }
29    }
30    break;
31case("unzip"):  //解压缩
32    string [] un_tmp =this.name1.Value.Split(new char[]{'*'});
33    int i2=0;         //防止名称冲突的参数
34    foreach(string un_tmp2 in un_tmp)
35    {
36        if(un_tmp2!="")
37        {
38            string un_time=System.DateTime.Now.ToShortDateString()+"-"+System.DateTime.Now.Hour.ToString()+"-"+System.DateTime.Now.Minute.ToString()+"-"+(System.DateTime.Now.Second+i2).ToString();
39            string un_dir =ServerDir+@"personal\Unzip-"+un_time;
40            Directory.CreateDirectory(un_dir);              //创建以解压时间为名的文件夹
41            StreamWriter un_sw=File.AppendText(ServerDir+"DirState.dat");
42            un_sw.Write(@"personal\Unzip-"+un_time+"*");
43            un_sw.Close();
44            System.Diagnostics.Process Process2=new System.Diagnostics.Process();
45            Process2.StartInfo.FileName=ServerDir+"Winrar.exe";
46            Process2.StartInfo.Arguments=" x -inul -y "+ServerDir+un_tmp2+" "+un_dir;
47            Process2.Start();        //进行解压
48            while(!Process2.HasExited)           //等待解压的完成
49            {
50            }
51            i2++;
52        }
53    }
54    break;
