将3-dim数组复制到11x3-dim数组中C＃

Question

我有这个C＃代码，它具有3-dim double，然后将其复制到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];

如何直接将temprate复制到RATES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));
