okay guys I'm seeing question from persons asking how to convert byte arrays to int, string, Stream, etc... and the answers to which are all varying and I have personally not found any satisfactory answers.
好吧伙计们，我看到有人询问如何将字节数组转换为int，string，Stream等等的问题......而且答案都各不相同，我个人没有找到任何满意的答案。
So here are some types that we want to convert an array of bytes to.
所以这里有一些我们想要将字节数组转换为的类型。
UnityEngine.Font which can take in ttf data.
UnityEngine.Font可以接收ttf数据。
UnityEngine.Testure2D which h can take in data from image files like .png, .jpg, etc...
UnityEngine.Testure2D，它可以从图像文件中获取数据，如.png，.jpg等...
How would we convert a byte array to a String, UnityEngine.Testure2D,UnityEngine.Font, Bitmap, etc...
我们如何将字节数组转换为String，UnityEngine.Testure2D，UnityEngine.Font，Bitmap等...
The data that populates the byte array must be from a file type whose data can by managed by the type we want to convert the byte array to?
填充字节数组的数据必须来自一个文件类型，其数据可以通过我们要将字节数组转换为的类型来管理？
Is this currently possible?
这目前可能吗？
Any help would be appreciated.
任何帮助，将不胜感激。

Primitive types are easy because they have a defined representation as a byte array. Other objects are not because they may contain things that cannot be persisted, like file handles, references to other objects, etc.
原始类型很容易，因为它们具有定义的表示形式作为字节数组。其他对象不是因为它们可能包含无法持久化的内容，例如文件句柄，对其他对象的引用等。
You can try persisting an object to a byte array using BinaryFormatter:
您可以尝试使用BinaryFormatter将对象持久化到字节数组：
public byte[] ToByteArray<T>(T obj)
{
if(obj == null)
return null;
BinaryFormatter bf = new BinaryFormatter();
using(MemoryStream ms = new MemoryStream())
{
bf.Serialize(ms, obj);
return ms.ToArray();
}
}
public T FromByteArray<T>(byte[] data)
{
if(data == null)
return default(T);
BinaryFormatter bf = new BinaryFormatter();
using(MemoryStream ms = new MemoryStream(data))
{
object obj = bf.Deserialize(ms);
return (T)obj;
}
}
But not all types are serializable. There's no way to "store" a connection to a database, for example. You can store the information that's used to create the connection (like the connection string) but you can't store the actual connection object.
但并非所有类型都可序列化。例如，没有办法“存储”与数据库的连接。您可以存储用于创建连接的信息（如连接字符串），但不能存储实际的连接对象。
