为什么这个C#代码没有编译？

public static Dictionary<short,MemoryBuffer> GetBulkCustom(int bufferId,int startSecond,out int chunksize,out int bardatetime)
{
    //const string _functionName = "GetNextBulkWatchData";

    UserSeriesCard currentCard = GetUserSeriesCard(bufferId);

    Dictionary<short,MemoryBuffer> result = null;

    while (currentCard.CurrentSecond <= startSecond)
        result = GetBulk(bufferId,out chunksize,out bardatetime);

    if (result == null)
    {
        result = currentCard.UserBuffer;
        chunksize = currentCard.ChunkSize;
        bardatetime = currentCard.CurrentBarDateTime;
    }
    return result;
}

错误：

The out parameter 'bardatetime' must be assigned to before control leaves the current method
The out parameter 'chunksize' must be assigned to before control leaves the current method

我想不出bardatetime和chunksize最终会被取消分配的情况.

编辑.我通过将代码调整为逻辑等效的代码来修复此错误.老实说,我想避免多重分配.

public static Dictionary<short,out int bardatetime )
    {
        const string _functionName = "GetNextBulkWatchData";

        UserSeriesCard currentCard = GetUserSeriesCard(bufferId);

        Dictionary<short,MemoryBuffer> result = null;
        chunksize = currentCard.ChunkSize;
        bardatetime = currentCard.CurrentBarDateTime;

        while (currentCard.CurrentSecond <= startSecond)
            result = GetBulk(bufferId,out bardatetime);

        if (result == null)
            result = currentCard.UserBuffer;

        return result;
    }
