将3-dim数组复制到11x3-dim数组C#中

Question

我有这个C#代码，它有一个3-dim双，然后将它复制到一个11x3双：

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];

如何将临时数据直接复制到费率中(最好没有循环)？

即："RATES[i,*]=temprate"

Answer 1

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