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.

You can try persisting an object to a byte array using <a href="https://msdn.microsoft.com/en-us/library/system.runtime.serialization.formatters.binary.binaryformatter" rel="noreferrer"><code>BinaryFormatter</code></a>:

<pre><code>public byte[] ToByteArray&lt;T&gt;(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&lt;T&gt;(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;
 }
}
</code></pre>

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.

okay guys I'm seeing question from persons asking how to convert byte arrays to <code>int</code>, <code>string</code>, <code>Stream</code>, etc... and the answers to which are all varying and I have personally not found any satisfactory answers.

So here are some types that we want to convert an array of bytes to.

<code>UnityEngine.Font</code> which can take in <code>ttf</code> data.

<code>UnityEngine.Testure2D</code> which h can take in data from image files like <code>.png</code>, <code>.jpg</code>, etc...

How would we convert a byte array to a <code>String</code>, <code>UnityEngine.Testure2D,UnityEngine.Font</code>, <code>Bitmap</code>, etc...

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?

Is this currently possible?

Any help would be appreciated.
