If statement not working after Type Convertion

I'm working with reflection and I need a business validation, so I created a class declared in the following way:

public class NullChecker<T>

There I created a method that run that validation:

public static T ReturnValue2(T serviceValue, T dbValue, Type propType)    
{
    T result;
    object svcValueConverted = serviceValue;
    object defaultValue = null;
    if (propType.IsPrimitive)
    {
       svcValueConverted = GetConvertedValue(serviceValue);
       defaultValue = GetDefaultValue(propType);
       var x = svcValueConverted.GetType();
       var y = defaultValue.GetType();
    }           
    if (svcValueConverted == defaultValue)
    {
         result = dbValue;
    }
    return result;
}

I'm getting this issue when a Int.32 object type comes, even that the converted value (0), and the default value (0) are the same, the if statement is not working and jump to the next line (i.e. 0 == 0). I don't really know which is the problem here, if anyone has experimented this, It would be nice to get some ideas.

Thank u in advance, happy code.
