Question

We have following classes

public class MyPropertyBase
{
    public int StartOffset { get; set; }
    public int EndOffset { get; set; }
}

public class MyProperty<T> : MyPropertyBase
{
    public MyProperty(T propertyValue)
    {
        PropertyValue = propertyValue;
    }

    public T PropertyValue { get; set; }
}

class BE
{
    public MyProperty<string> FUND_CITY { get; set; }

    public MyProperty<int> SomeOtherProperty { get; set; }

    public List<MyPropertyBase> MyDataPoints { get; set; }
}

When I create instance of BE as objBE and assign objBE.FUND_CITY="Some Value" it gives the error:

“Can’t convert “string” to MyProperty.

Answer 1

That’s correct. FUND_CITY is not a string, but is a MyProperty<string> type. You’ll need to do:

objBE.FUND_CITY = new MyProperty<string>("Some Value").

Or, if you have a parameterless constructor, you can do:

objBE.FUND_CITY = new MyProperty<string>();
objBE.FUND_CITY.PropertyValue = "Some Value";
