Filtering a collectiion

Question

Hi I am using the following code to filter entries. public CollectionEx Filter(CollectionEx pList String pPropertyName object pFilterValue) { CollectionEx filteredList = new CollectionEx (); foreach (T item in pList) { Type itemType = item.GetType(); PropertyInfo propertyInfo = item.GetType().GetProperty(pPropertyName); object valueOfX = propertyInfo.GetValue(item null); if (valueOfX == pFilterValue) { filteredList.Add(item); } } return filteredList; } Even in situations where the objects are equal this statement always evaluates to false. if (valueOfX == pFilterValue) Where am i going wrong?

See if it makes any difference if you use the virtual Equals() method rather than the == operator: if (pFilterValue.Equals(valueOfX))

If both objects contain string data that is similar the compare still returns false. However forcing a conversion to a string using ToString() method returns true.

When you say it returns false even when the objects are 'equal' do you mean that the operands of the == operator are references to the same object or that the objects are 'equal' in some other sense - for example in the case of strings that they contain the same characters in the same order?
