Receive bytea with asp .net api - entity-framework

Question

First of all, sorry for the probable English mistakes
I created a table in my postgresql database using the entity framework.
In edmx in the creation section I passed as bytea, however in the mapping I used binary (primitive type use is necessary).
<EntityType Name="styleexample">
<Key>
<PropertyRef Name="id" />
</Key>
<Property Name="id" Type="Int32" Nullable="false" annotation:StoreGeneratedPattern="Identity" />
<Property Name="example" Type="String" MaxLength="40" />
<Property Name="example1" Type="Binary" />
<Property Name="example2" Type="DateTime" />
</EntityType>
<EntityType Name="styleexample">
<Key>
<PropertyRef Name="id" />
</Key>
<Property Name="id" Type="int4" StoreGeneratedPattern="Identity" Nullable="false" />
<Property Name="example" Type="varchar" MaxLength="40" />
<Property Name="example1" Type="bytea" />
<Property Name="example2" Type="timestamp" />
</EntityType>
The table was created with the correct typing
In the entity I referenced the column as byte []
In the column I inserted the base64 string of a png image, but in the service when I return the value is different from what I inserted
My response is also byte[]
It works. However, it returns the incorrect value. Is there a different way to do this process?

I solved the issue by adding to the service
var example1 = new StreamReader(new MemoryStream(estilo.example1));
var example1Stream = example1 .ReadToEnd();
