将 3-dim 数组复制到 11x3-dim 数组 C#

Question

我有这个 C# 代码，它有一个 3-dim 双精度，然后将它复制到一个 11x3 双精度：

var i = 8;
var temprate = new double[]{1,2,3};
var RATES = new double[11,3]

RATES[i, 0] = temprate[0];
RATES[i, 1] = temprate[1];
RATES[i, 2] = temprate[2];

如何将 temprate 直接复制到 RATES 中（最好不要循环）？

即："RATES[i,*]=temprate"

Answer 1

Buffer.BlockCopy(temprate, 0, RATES, i * 3 * sizeof(double), 3 * sizeof(double));
