c++ - Visual C++ 2010 注释导致错误

Question

// hi注释会导致红色波浪线出现在、 和它下面的if语句中、hashTable、ItemType*和hashTableSize。错误是“预期的if声明”，hashTable错误是“此声明没有存储类或类型说明符”，ItemType*错误是“预期的类型说明符”，hashTableSize错误是“标识符'HashTableSize'未定义。删除注释删除波浪线。我的项目中没有其他班级有这个问题。什么给了？

template <class ItemType>
HashedDictionary( const unsigned & p_hashTableSize = DEFAULT_SIZE ) : hashTable( NULL ), hashTableSize( p_hashTableSize ), itemCount( 0 )
{
    // hi

    if ( hashTableSize < 0 )
        throw PrecondViolatedExcep( "Hash table size must be greater than or equal to zero." );

    hashTable = new ItemType*[ hashTableSize ]; 

}

类声明：

#include "HashedEntry.h"

template< class ItemType>

    class HashedDictionary
    {
    private:
        HashedEntry<ItemType>** hashTable;
        unsigned hashTableSize;
        unsigned itemCount;
        static const unsigned DEFAULT_SIZE = 101;

        int getHashIndex( const ItemType & newEntry );
        int computeIndex( const ItemType & newEntry );
    public:
        HashedDictionary( const unsigned & p_hashTableSize );
        bool add( const ItemType & newItem );

    }
