在C#中,二维数组可以与其他数据结构(如列表、字典等)进行转换
int[,] array = new int[,] { { 1, 2 }, { 3, 4 }, { 5, 6 } };
List<List<int>> list = new List<List<int>>();
for (int i = 0; i< array.GetLength(0); i++)
{
List<int> innerList = new List<int>();
for (int j = 0; j< array.GetLength(1); j++)
{
innerList.Add(array[i, j]);
}
list.Add(innerList);
}
List<List<int>> list = new List<List<int>>()
{
new List<int> { 1, 2 },
new List<int> { 3, 4 },
new List<int> { 5, 6 }
};
int[,] array = new int[list.Count, list[0].Count];
for (int i = 0; i< list.Count; i++)
{
for (int j = 0; j< list[i].Count; j++)
{
array[i, j] = list[i][j];
}
}
int[,] array = new int[,] { { 1, 2 }, { 3, 4 }, { 5, 6 } };
Dictionary<int, int> dictionary = new Dictionary<int, int>();
for (int i = 0; i< array.GetLength(0); i++)
{
for (int j = 0; j< array.GetLength(1); j++)
{
dictionary[i * array.GetLength(1) + j] = array[i, j];
}
}
Dictionary<int, int> dictionary = new Dictionary<int, int>()
{
{ 0, 1 },
{ 1, 2 },
{ 2, 3 },
{ 3, 4 },
{ 4, 5 },
{ 5, 6 }
};
int rows = (int)Math.Sqrt(dictionary.Count);
int cols = dictionary.Count / rows;
int[,] array = new int[rows, cols];
for (int i = 0; i< rows; i++)
{
for (int j = 0; j< cols; j++)
{
array[i, j] = dictionary[i * cols + j];
}
}
这些示例展示了如何在C#中将二维数组与其他数据结构进行转换。请根据实际需求调整代码。
