Re: Web service & ArrayList
Ah... found this old thread:
http://forum.springframework.net/showthread.php?t=5274
I will list my solution here if other people have the same problem.
In short: ArrayList can't be used, one must use List<type> instead,
thus...
Server code:
Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Collections;
namespace ClassLibrary1
{
[ServiceContract(Namespace="http://somesite.com")]
public interface IMainClass
{
[OperationContract]
string Hello();
[OperationContract]
[System.Xml.Serialization.XmlInclude(typeof(CustomersDataClass))]
List<CustomersDataClass> GetData();
}
public class MainClass : IMainClass
{
public string Hello()
{
return "Hello!";
}
public List<CustomersDataClass> GetData()
{
List<CustomersDataClass> a = new List<CustomersDataClass>();
a.Clear();
CustomersDataClass temp = new CustomersDataClass();
temp.CompanyName = "1";
temp.ContactName = "2";
temp.CustomerID = "3";
a.Add(temp);
temp = new CustomersDataClass();
temp.CompanyName = "4";
temp.ContactName = "5";
temp.CustomerID = "6";
a.Add(temp);
return a;
}
}
[Serializable]
public class CustomersDataClass
{
private string _CustomerID, _CompanyName, _ContactName;
public string CustomerID
{
get { return _CustomerID; }
set { _CustomerID = value; }
}
public string CompanyName
{
get { return _CompanyName; }
set { _CompanyName = value; }
}
public string ContactName
{
get { return _ContactName; }
set { _ContactName = value; }
}
}
}
Client code
Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ServiceModel;
using System.Collections;
namespace WebApplication1
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
MainClassClient client =
new MainClassClient();
client.Open();
string s = client.Hello();
TextBox1.Text = s;
ClassLibrary1.CustomersDataClass[] arr = client.GetData();
client.Close();
}
}
}

Re: Web service & ArrayList
Or return a raw array.
Code:
public CustomersDataClass[] GetData()
{
List<CustomersDataClass> a = new List<CustomersDataClass>();
a.Clear();
CustomersDataClass temp = new CustomersDataClass();
temp.CompanyName = "1";
temp.ContactName = "2";
temp.CustomerID = "3";
a.Add(temp);
temp = new CustomersDataClass();
temp.CompanyName = "4";
temp.ContactName = "5";
temp.CustomerID = "6";
a.Add(temp);
return a.ToArray( );
}
A reason to return a raw array would be for better compatibility with clients that don't know about List<>.
