C#：是否可以将一个 2darray 放置在另一个 2darray 中的某个位置而不迭代它？
是否可以将一个二维数组放置在另一个二维数组中的某个位置而不迭代它？
public double[,] array2D;
array2D = new double[7,7];
public void fill1D(double[,] values)
{
Array2D = values; //Values holds a 5x5 array that i wan't to place from 1,1 in array2D
}
谢谢
Is it possible to position a 2d array in a certain position in another 2d array without iterating through it?
public double[,] array2D;
array2D = new double[7,7];
public void fill1D(double[,] values)
{
Array2D = values; //Values holds a 5x5 array that i wan't to place from 1,1 in array2D
}
Thanks

不，你不能（编辑：不复制），对不起。您可以使用 ArraySegement 来模拟这一点（但您必须使用一维基本数组。您可能还想阅读 这篇论文表明普通矩形数组在 C# 中相对较慢。
No you can't (edit: without copying) , I'm sorry. You could mimic this perhaps with the
ArraySegement(but you'd have to use a 1D base array. You may also care to read this paper that suggests plain rectangular arrays are relatively slow in C#.
