Most efficient way to merge two byte arrays into one byte array?
提问by Nano White
I have two byte arrays. I want to merge these two byte arrays into one byte array.
我有两个字节数组。我想将这两个字节数组合并为一个字节数组。
Usually, I just create a new byte array with length = byte array #1 + byte array #2. Then copy byte array #1 and #2 to the new byte array.
通常，我只是创建一个长度 = 字节数组 #1 + 字节数组 #2 的新字节数组。然后将字节数组#1 和#2 复制到新的字节数组中。
Is there a more efficient way to merge two byte arrays using VB.NET and .NET 4?
是否有更有效的方法来使用 VB.NET 和 .NET 4 合并两个字节数组？
回答by Jon
Your existing approach is the most efficient (for what I think is the commonly understood meaning of "efficient") as long as it is implemented properly.
只要正确实施，您现有的方法是最有效的（因为我认为这是“高效”的普遍理解的含义）。
The implementation should look like this:
实现应该是这样的：
var merged = new byte[array1.Length + array2.Length];
array1.CopyTo(merged, 0);
array2.CopyTo(merged, array1.Length);

In our Tcpclient we like to use Buffer.BlockCopy instead of array.copy.
在我们的 Tcpclient 中，我们喜欢使用 Buffer.BlockCopy 而不是 array.copy。
