Question

I need to check if an object contains any value. The following function works fine if the object is a String type but I was looking to replace this with a generic way without checking for the type. Is there a way to do this? Thanks in advance.

 public void SetValue(int id, object fieldData)
    {
        if (fieldData!=null)
        {
            if (fieldData.GetType() == typeof(String) && fieldData.Equals(string.Empty))
            {
                return;
            }
        }

        SetLOValue(id, fieldData);
    }

You can check for default types if you make it generic, but you have to be sure that’s what you want. i.e. is 0 a valid number in your usage?

if (fieldData == default(T))
{
  return;
}

Alternatively, you could switch to Nullable types.

if (fieldData.HasValue)...
