How to get a property's value from an other class object in a list

Question

I'm learning C# and it's not clear for me how to access a property in a foreach loop of FieldsList class. It was not accessible. I'm try to get a string concatenation with name of FieldData .

What's wrong?

namespace MyNamesp
{
    public class FldData
    {
        public string Name { get; set; }
        public Type FldType { get; set; }

        public FldData() { }

        public FldData(string name, Type fldType)
        {
            Name = name;
            FldType = fldType;
        }
    }


    class FieldsList<FldData> : List<FldData>
    {
        public int NumField { get { return this.Count; }  }
        public string QryFieldList()
         {

           string _QryFieldList = "";

            foreach(FldData fld in this)
            {
                _QryFieldList += fld.Name +",";  //Fld.Name is not accessible 
            }

            return _QryFieldList;
        }

    }
}

Answer 1

The definition of the FieldsList class shouldn't have a generic type argument,
just declare it as here below.

When defined as FieldsList<FldData> , the FldData part is considered as the generic type argument which is not the FldData class, although both names are similar.

class FieldsList : List<FldData>
{
    public int NumField { get { return this.Count; } }
    public string QryFieldList()
    {

        string _QryFieldList = "";

        foreach (FldData fld in this)
        {
            _QryFieldList += fld.Name + ",";
        }

        return _QryFieldList;
    }
}
