I have a couple questions about byte arrays 我对字节数组有几个问题

My first question this is a byte array correct? 我的第一个问题是字节数组正确吗？ byte[] array = {0x90, 0x38, 0x83, 0x49}

question 2 is would memorystream.ToArray(); 问题2是memorystream.ToArray(); produce the same as question 1 or am I wrong. 产生与问题1相同的结果或我错了。

If i am wrong how can i produce question 1 with question 2 or is it not possible? 如果我错了，我该如何将问题1和问题2相提并论？

Thank you 谢谢

Q1: byte[] array is an array of type "byte" which is commonly referred to as "byte array". Q1： byte[] array是类型为“ byte”的数组，通常称为“ byte array”。

Mind that byte is an alias for System.Byte . 注意该byte是System.Byte的别名。 So you could come across Byte[] , which will also be referred to as "byte array". 因此，您可能会遇到Byte[] ，也将其称为“字节数组”。 ( Also mind, that this can be quite different in other languages like Java! ) （还要注意，这在其他语言（如Java）中可能会大不相同！）

Q2: MSDN says: Q2： MSDN说：

Writes the stream contents to a byte array, regardless of the Position property. 不管Position属性如何，将流内容写入字节数组。

So given the MemoryStream's contents are the bytes mentioned, then yes, you would get a byte array with the bytes of q1. 所以给定MemoryStream的内容是提到的字节，那么是的，您将获得一个带有q1字节的字节数组。
