如何使用从Web服务获得的arraylist填充下拉列表

Question

I am consuming a java web service in asp.net, the method is an arraylist that devuleve the code and name, and I do not know how to load it to a dropdonwlist in which it shows the name and value is the code.

I tried the following way:

WebReferences.agencia datos = new WebReferences.agencia();

listAgencia.DataSource = datos;
listAgencia.DataTextField = datos.nombre;
listAgencia.DataValueField = Convert.ToString(datos.ida);
listAgencia.DataBind();

It gives me error in the datasource.

Answer 1

As you access properties nombre and ida from datos , it seems that datos isn't a collection but a single object.

In this case this would be enough:

listaAgencia.Items.Add(new ListItem(datos.nombre, datos.ida.ToString()));

Should datos be a collection, instead, I would do like this:

foreach (var singleData in datos)
   listaAgencia.Items.Add(new ListItem(singleData.nombre, singleData.ida.ToString()));
