Question

I am new to c# so bit stuck at what I thought was a very simple module. I just need to display data in the dropdown menu but getting some error while binding… or I will say even before binding. Here is what I am trying to do..I am really sorry if I am doing a very simple mistake but I tried my best & now I think I need some guidance..

CustomService.cs

public partial class CustomService
{
public List<Code> GetDepartment(bool activeOnly)
    {
        List<Code> retVal = new List<Code>();
        ---some code----
        return retVal;
    }
     }

ProgramList.ascx.cs

protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            List<Code> dept = new List<Code>CustomService.GetDepartment(true);
            ddlDepartment.DataSource = dept;
            ddlDepartment.DataBind();
         }
    } 
   //error an object reference is required for an nonstatic field, method or Property CustomService.GetDepartment(true);

Answer 1

you forgot to create object first and than you can call the method

another thing is you just need to assign the value directly as i did below, there is no need to create any new list

check the code below that will work for you

CustomService custsrv = new CustomService();
List<Code> dept = custsrv.GetDepartment(true);
