如何通过HTTPPost方法将数组作为参数传递给ASP.NET webservice？

Question

@Override
    protected String doInBackground(String... params)
    {
        String s="";
        for( int i=1;i< Amount_1.length;i++) {            
            String jsonurl = "http://rsk.abc.com/WebService1.asmx/Insert";
            date = null;
            try {
                amount[0]= "10000";
                name[0]= "jack";
                amount[1]= "100000";
                name[1]= "harris";                   

                HttpClient httpClient = new DefaultHttpClient();
                HttpPost httpPost = new HttpPost(jsonurl);
                List<NameValuePair> list = new ArrayList<NameValuePair>();
                list.add(new BasicNameValuePair("name", name[i]));
                list.add(new BasicNameValuePair("amount", amount[i]));

                httpPost.setEntity(new UrlEncodedFormEntity(list));
                HttpResponse httpResponse = httpClient.execute(httpPost);
                HttpEntity httpEntity = httpResponse.getEntity();
                // s= readResponse(httpResponse);
               s = getJSONString(httpResponse);
            } catch (Exception exception) {
                String err = exception.getMessage().toString();
                return err;
            }
        }
        return s;
    }
}


[WebMethod(Description = "Transaction")]
    [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
    public string Insert(
        string[] name,
        string[] amount,
        )
        {
            string msg = "";
            SqlCommand[] cmd3= new SqlCommand[10];
            SqlTransaction trans = null;
            con.Open();
            string a = Insert_firsttable(name[0],amount[1]);
            string b=Insert_secondtable(name[1],amount[1]);
            cmd3[0] = new SqlCommand(a, con);
            cmd3[1]= new SqlCommand(b, con);
            trans = con.BeginTransaction();


            cmd3[0].Transaction = trans;
            cmd3[1].Transaction = trans;
        }
        try
        {
            for (int j = 0; j < 2; j++)
            {
                 cmd3[j].ExecuteNonQuery();
            }

            trans.Commit();
            trans = null;
            msg = "success";
            return msg;
        }

        catch (Exception)
        {
            msg = "oooops";
            if (trans != null)
            {

                trans.Rollback();
                trans = null;
                msg = "oops";
            }
            return msg;
        }
        finally
        {
            con.Close();
        }
    }

我能够将参数作为字符串传递。但不能作为数组参数。我不知道如何传递数组作为参数。我需要在webmethod.so中插入事务内的两个表，我需要将参数作为数组传递。
