如何在c#中返回数据表和整数

Question

我正在创建一个返回值datatable 和一个int值的方法.我创建了一个只返回的方法datatable.请查看代码

    public static  DataTable ShutterstockSearchResults(string url)
    { 

       int TotalCont=0;

        DataTable dt = new DataTable();
        try
        {
            //intigration using Basic Aouth with authrization headers

            var request = (HttpWebRequest)WebRequest.Create(url);
            var username = "SC";
            var password = "SK";
            string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(username + ":" + password));
            request.Headers[HttpRequestHeader.Authorization] = string.Format("Basic {0}", credentials);
            request.UserAgent = "MyApp 1.0";
            var response = (HttpWebResponse)request.GetResponse();
            using (var stream = response.GetResponseStream())
            using (var reader = new StreamReader(stream))
            {
                JavaScriptSerializer js = new JavaScriptSerializer();
                var objText = reader.ReadToEnd();
                SearchResult myojb = (SearchResult)js.Deserialize(objText, typeof(SearchResult));
               TotalCount = myojb.total_count;          

                dt.Columns.Add("Id");
                dt.Columns.Add("Discription");
                dt.Columns.Add("Small_Thumb_URl");
                dt.Columns.Add("Large_Thumb_URL");
                dt.Columns.Add("Prieview_URL");
                dt.Columns.Add("ContributorID");
                dt.Columns.Add("aspect");
                dt.Columns.Add("image_type");
                dt.Columns.Add("is_illustration");
                dt.Columns.Add("media_type");
                foreach (var item in myojb.data)
                {
                    var row = dt.NewRow();
                    row["ID"] = item.id;
                    row["Discription"] = item.description;
                    row["Small_Thumb_URl"] = item.assets.small_thumb.url;
                    row["Large_Thumb_URL"] = item.assets.large_thumb.url;
                    row["Prieview_URL"] = item.assets.preview.url;
                    row["ContributorID"] = item.contributor.id;
                    row["aspect"] = item.aspect;
                    row["image_type"] = item.image_type;
                    row["is_illustration"] = item.is_illustration;
                    row["media_type"] = item.media_type;
                    dt.Rows.Add(row);
                }
                // List<SearchResult> UserList = JsonConvert.DeserializeObject<List<SearchResult>>(objText);
                // Response.Write(reader.ReadToEnd());
            }          

        }

        catch (WebException ea)
        {

            Console.WriteLine(ea.Message);
            using (var stream = ea.Response.GetResponseStream())
            using (var reader = new StreamReader(stream))
            {
                Console.WriteLine(reader.ReadToEnd());
            }
        }

        return dt;

    }

我想回到datatable和TotalCont.请帮助

Answer 1

一般来说,一种方法只能返回一种类型.

您有两种选择:

1)创建一个具有a DataTable和intfield的类,例如:

public class MyReturnType
{
     public DataTable TheDataTable {get; set;}
     public int TotalCount {get; set;}
}

并从您的方法返回此类型.

2)您可以out在方法中添加参数:

public static  DataTable ShutterstockSearchResults(string url, out totalCount)

并totalCount在您的方法中分配.
