C＃中的数组串联(Array concatenation in C#)

C＃中的数组串联(Array concatenation in C#)

我如何在C＃中用两个（或更多）其他数组巧妙地初始化一个数组？

double[] d1 = new double[5]; double[] d2 = new double[3]; double[] dTotal = new double[8]; // I need this to be {d1 then d2}

另一个问题：我如何高效地连接C＃数组？

How do I smartly initialize an Array with two (or more) other arrays in C#?

double[] d1 = new double[5]; double[] d2 = new double[3]; double[] dTotal = new double[8]; // I need this to be {d1 then d2}

Another question: How do I concatenate C# arrays efficiently?

最满意答案

您可以使用CopyTo ：

double[] d1 = new double[5]; double[] d2 = new double[3]; double[] dTotal = new double[d1.Length + d2.Length]; d1.CopyTo(dTotal, 0); d2.CopyTo(dTotal, d1.Length);

You could use CopyTo:

double[] d1 = new double[5]; double[] d2 = new double[3]; double[] dTotal = new double[d1.Length + d2.Length]; d1.CopyTo(dTotal, 0); d2.CopyTo(dTotal, d1.Length);
