Hi
I'm having trouble retrieving an arraylist from my webservice.
My webmethod returns a collection of object Task as follows.
[
WebMethod]
[
return: XmlElement(typeof(Workflow.Task))]
public List<Task> GetAllTasks()
{
SqlConnection cn = null;
SqlDataReader rd = null;
try
{
cn =
new SqlConnection(connection);
SqlCommand cmd = new SqlCommand("GetAllTasks",cn);
cmd.CommandType =
CommandType.StoredProcedure;
cn.Open();
rd = cmd.ExecuteReader();
tasks.Clear();
while (rd.Read())
{
int actID = 0;
int nodeID = 0;
int userID = 0;
if (!rd.IsDBNull(0)) actID = Convert.ToInt32(rd.GetValue(0));
if (!rd.IsDBNull(1)) nodeID = Convert.ToInt32(rd.GetValue(1));
if (!rd.IsDBNull(2)) userID = Convert.ToInt32(rd.GetValue(2));
Task
tk = new Task(actID, nodeID, userID);
tasks.Add(tk);
}
rd.Close();
cn.Close();
return tasks;
}
catch (Exception ex)
{
throw new Exception(ex.Message); }
}
[
Serializable, XmlInclude(typeof(Task))]
public class Task
{
private int actID = 0;
private int nodeID = 0;
private int userID = 0;
public int ActionID
{
get { return actID; }
set { actID = value; }
}
public int NodeID
{
get { return nodeID; }
set { nodeID = value; }
}
public int UserID
{
get { return userID; }
set { userID = value; }
}
public Task()
{
}
internal Task(int ActionID, int NodeID, int UserID)
{
this.actID = ActionID;
this.nodeID = NodeID;
this.userID = UserID;
}
}
In my web app I'm trying to access the arraylist as follows but it returns a blank arraylist. But if I step thru it the webservice arraylist contains value but is not returning it to the application.
web app code:
localhost.Workflow wFlowService = new localhost.Workflow();
ArrayList Tasks = new ArrayList(wFlowService.GetAllTasks());
Can anyone assist me here.
Thanks
Thav
