I am creating a method which returns datatable
and an int
value.I have create a method which returns only datatable
.Please take a look on the code
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;
}
I want to return datatable
and TotalCont
.please help

public static Tuple<DataTable, int> ShutterstockSearchResults(string url)
{
[...]
return new Tuple<DataTable, int>(dt, totalCount);
}
public static void SomeConsumerMethod()
{
var result = ShutterstockSearchResults(myPath);
DataTable dt = result.Item1;
int totalCount = result.Item2;
}

You can accomplish this with a Tuple. Consider the following simple example:
public class EmptyClass
{
public static void Main(){
EmptyClass something = new EmptyClass ();
Tuple<String, int> tuple = something.returnMe ();
Console.WriteLine ("Item 1: " + tuple.Item1);
Console.WriteLine ("Item 2: " + tuple.Item2);
}
public EmptyClass ()
{
}
public Tuple<String, int> returnMe() {
return Tuple.Create ("Hello", 2);
}
}

Your method needs an additional out
parameter if you want to "return" more than one value. Just pass an uninitialized variable of the desired type into your method and assign that variable inside.
public void Test()
{
int i;
DataTable ShutterstockSearchResults("Some string", out i);
}
your ShutterstockSearchResults
method needs to be modified accordingly:
public static DataTable ShutterstockSearchResults(string url, out int outParam)
{
outParam = 10;
// do other stuff
}
If you do not change outParam
any further inside ShutterstockSearchResults
, it will have the value 10 after returning to Test
.

To answer the comments in Klaus answer:
public class MyReturnType
{
public DataTable TheDataTable {get; set;}
public int TotalCount {get; set;}
}
and in your method:
public static MyReturnType ShutterstockSearchResults(string url)
{
MyReturnType result=new MyReturnType();
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());
}
}
result.TheDataTable=dt;
result.TotalCount=TotalCount;
return result:
}

Generally speaking, a method can only return one type.
You have two options:
1) Create a class that has a DataTable
and an int
field, such as:
public class MyReturnType
{
public DataTable TheDataTable {get; set;}
public int TotalCount {get; set;}
}
And return this type from your method.
2) You can add an out
parameter to your method:
public static DataTable ShutterstockSearchResults(string url, out totalCount)
And assign to totalCount
within your method.
