将锯齿状数组转换为几个一维数组

Question

我想知道是否有一种方法可以将锯齿状数组（例如[3][]转换为三个一维数组？

Answer 1

Something like this? Assuming jagged is defined as int[3][] :

int[] first = jagged[0];
int[] two = jagged[1];
int[] three = jagged[2];

Each element in the first dimension of jagged is an array in and of itself - there is no need to convert.

Answer 2

It already is three one-dimensional arrays, effectively. Jagged arrays are not treated specially by the CLR, they are simply arrays of arrays. You just index the outer array to get one of the inner arrays.

Example:

var array1 = jaggedArray[0];
var array2 = jaggedArray[1];
var array3 = jaggedArray[2];
