我想将以下类从 java 转换为 C#：

public class ValueComparator implements Comparator{

    @Override
    public int compare(Object ob1, Object ob2){
        int retval = 0;
        if ( ob1 instanceof DataCol && ob2 instanceof DataCol ){
            DataCol c1 = (DataCol) ob1;
            DataCol c2 = (DataCol) ob2;
            if( c1.value < c2.value ) retval = 1;
            if( c1.value > c2.value ) retval = -1;
        } else {
            throw new ClassCastException("ValueComparator: Illegal arguments!");
        }
        return(retval);
    }    
}
