技术人员——当我有一个单一的频道或当我有一个偶数分割时，这个代码就可以工作。当我有剩余时，它几乎可以工作......因为它会创建下一个频道，它会拉入项目，但随后会超出范围。这些行是问题的核心：
items_per_batch = batchcount / (int)channels; //
subsets = batch.Split(items_per_batch);
items_per_batch 真正用于为拆分扩展提供一个关于拆分多少项目的通用数字的概念。如果它看到一个余数，它只是创建另一个子集数组。我真正需要做的是跟踪项目的长度。我试过：
int idx2 = subset.GetLength(1)
在某一时刻，但使用该值的 forloop 也超出了范围。有人有什么建议吗？
static void channelassign()
{
int THRESHOLD = 2;
string[] batch = new string[]
{ "item1", "item2", "item3", "item4","item5","item6","item7" };
int batchcount = batch.Count();
int items_per_batch;
string[][] subsets;
int idx1;
int idx2;
if (THRESHOLD != 0) //avoid accidental division by 0.
{
float channels = batchcount / THRESHOLD;
if (channels < 1)
{
channels = 1; // only 1 channel is needed
items_per_batch = batchcount; // process all items
idx1 = 1; // fix value to a single channel
idx2 = (batchcount - 1); // true start of array is 0
subsets = batch.Split(batchcount); //splits correctly
}
else
{
// decide how many items will be included per batch
channels = (int)Math.Round(channels,
MidpointRounding.ToEven); //determines channel number
items_per_batch = batchcount / (int)channels; //
subsets = batch.Split(items_per_batch);
idx1 = subsets.GetLength(0); // gets channel# assigned by split
// idx2 = subsets.GetLength(1); // gets items back from splits
}
//distribute contents of batch amongst channels
for (int channel = 0; channel < idx1; channel++)
{
for (int i = 0; i < items_per_batch; i++)
{
Console.WriteLine(" Channel:" + channel.ToString() + "
ItemName: {0} ", subsets[channel][i]);
}
}
}
else
{
Console.WriteLine("Threshold value set to zero. This
is an invalid value. Please set THRESHOLD.");
}
