Question

c# 两个byte[]怎么相叠加

如：{01,01,02}+{0d,00,df}={01,01,02,0d,00,df}?

Answer 1

//把b接在a的后面
byte[]
a = new byte[] { 1, 2, 3 },
b = new byte[] { 4, 5, 6 };

//.net3.5以上的linq方法
a = a.Concat(b).ToArray();

//.net3.0 2.0的方法
Array.Resize(ref a, a.Length+b.Length);
b.CopyTo(a, a.Length - b.Length);

Answer 2

byte[] b = new byte[] { 1, 2, 3 };
byte[] c = new byte[] { 4, 5, 6 };
b = b.Concat(c).ToArray();
