Question

My struct class:

public struct PinAndRadius
{
    public string pinID { get; set; }
    public string radiusID { get; set; }

    public string getPinID()
    {
        return pinID;
    }

    public string getRadiusID()
    {
        return radiusID;
    }
}

the method with a problem:

void mapArea_VE_PinDragged(double latitude, double longitude, object id)
{
    foreach (var pin in pinRadiusCollection)
    {
        string ID = id.ToString();
        //string newID = ID.Substring(0, 18);
        if (!pin.Key.pinID.Equals(ID))
        {
            continue;
        }
        else if (pin.Key.pinID.Equals(ID))
        {
            var newLoc = createNewSearchLocation(latitude, longitude);
            mapArea.VE_DeleteRadius(pin.Key.radiusID);
            drawPoly(newLoc, pin.Value.xar_Radius);
            pin.Key.radiusID = pollyID;
            break;
        }
    }
}

The problem is that when I try to set pin.key.radiusID to pollyID, I get an error saying

Cannot modify the return value of ‘System.Collections.Generic.KeyValuePair.Key’ because it is not a variable…

Any ideas?

I simply just changed the struct definition to a class.
