把数组分批遍历,请给出csharp代码

Sure, here's some sample C# code for iterating over an array in batches:
```
int batchSize = 10;
int[] myArray = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };
int numberOfBatches = myArray.Length / batchSize;
for (int i = 0; i <= numberOfBatches; i++)
{
int startIndex = i * batchSize;
int endIndex = Math.Min(startIndex + batchSize, myArray.Length);
for (int j = startIndex; j < endIndex; j++)
{
Console.WriteLine(myArray[j]);
}
}
```
This code will iterate over an array of integers in batches of 10, printing each element to the console. If the length of the array is not divisible by the batch size, the final batch will contain the remaining elements.

把数组分批遍历到一个新数组,请给出csharp代码
以下是分批遍历数组并生成新数组的 C# 代码:
```
public static T[] BatchedArray<T>(T[] sourceArray, int batchSize)
{
int numberOfBatches = (int)Math.Ceiling((double)sourceArray.Length / batchSize);
T[] resultArray = new T[numberOfBatches];
for (int i = 0; i < numberOfBatches; i++)
{
int currentIndex = i * batchSize;
T[] currentBatch = new T[Math.Min(batchSize, sourceArray.Length - currentIndex)];
for (int j = 0; j < currentBatch.Length; j++)
{
currentBatch[j] = sourceArray[currentIndex + j];
}
resultArray[i] = currentBatch;
}
return resultArray;
}
```
使用方法:
```
int[] sourceArray = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
int batchSize = 3;
int[][] resultArray = BatchedArray(sourceArray, batchSize);
// Output: {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}, {10}}
Console.WriteLine(string.Join(", ", resultArray.Select(batch => $"{{{string.Join(", ", batch)}}}")));
```
Arrays数组遍历
当遍历数组时,我们可以使用循环来访问数组中的每个元素。有多种方法可以遍历数组,比如使用for循环、foreach循环或者while循环。
对于一维数组,我们可以使用以下代码示例来展示不同的遍历方法:
1. 使用for循环遍历数组:
```csharp
int[] arr = { 1, 2, 3, 4, 5 };
for (int i = 0; i < arr.Length; i++)
{
Console.WriteLine(arr[i]);
}
```
2. 使用foreach循环遍历数组:
```csharp
int[] arr = { 1, 2, 3, 4, 5 };
foreach (int num in arr)
{
Console.WriteLine(num);
}
```
无论使用哪种循环方式,都可以逐个访问数组中的元素,并进行相应的操作。
