C#将一维数组分配给二维数组语法 [英] c# assign 1 dimensional array to 2 dimensional array syntax

问题描述

我想做类似的事情:

object[] rowOfObjects = GetRow();//filled somewhere else
object[,] tableOfObjects = new object[10,10];

tableOfObjects[0] = rowOfObjects;

这有可能吗?语法是什么?

is this somehow possible and what is the syntax?

或者我需要这样做:

for (int i = 0; i < rowOfObjects.Length; i++)
{
   tableOfObjects[0,i] = rowOfObjects[i];
}

并使用循环填充二维数组行?

and fill up the 2 dimensional arrays row using a loop?

谢谢

推荐答案

否，如果您使用的是二维数组，则不可能.您必须复制每个项目.

No, if you are using a two dimensional array it's not possible. You have to copy each item.

如果使用锯齿状数组，则可以正常工作:

If you use a jagged array, it works just fine:

// create array of arrays
object[][] tableOfObject = new object[10][];
// create arrays to put in the array of arrays
for (int i = 0; i < 10; i++) tableOfObject[i] = new object[10];

// get row as array
object[] rowOfObject = GetRow();
// put array in array of arrays
tableOfObjects[0] = rowOfObjects;

如果将所有数据作为行获取，那么您当然不需要将数组放入数组的循环，因为无论如何您都将替换它们.

If you are getting all the data as rows, you of course don't need the loop that puts arrays in the array of arrays, as you would just replace them anyway.
