C# Binary serialization into a variable

Question

I have a piece of code working that serialized a string into XML with XmlSerializer. I want to serialize the same string into binary and Not xml, I have tried different codes but none working, if possible please rewrite the following code to output me a serialized binary and store it in a variable.

public  class SerialTest
{
    public static void Main(string[] s)
    {
        String test = "ASD";
        string serializedData = string.Empty;                   

        XmlSerializer serializer = new XmlSerializer(test.GetType());
        using (StringWriter sw = new StringWriter())
        {
            serializer.Serialize(sw, test);
            serializedData = sw.ToString();
            Console.WriteLine(serializedData);
            Console.ReadLine();
        }
    }
}

What I actually want is to have a code that serialize an object and give me the serialized binary as output in a variable and not XML.

Have you looked into this learn.microsoft.com/en-us/dotnet/standard/serialization/… ? — Gabriel Costin

@GabrielCostin, Yes but it store the result in a file, I cant have it in a variable. — Emily Wong

Can you be clearer about your requirements? Do you want real binary data (byte[]) or Hex (string) ? And maybe also indicate what you need it for. — Henk Holterman

If you need to store Binary Serialization output inside a string, for that you can use ToBase64String like following.

String test = "ASD";
string serializedData = string.Empty;
MemoryStream memoryStream = new MemoryStream();
BinaryFormatter binaryFormatter = new BinaryFormatter();
binaryFormatter.Serialize(memoryStream, test);
memoryStream.Flush();
memoryStream.Position = 0;
serializedData = Convert.ToBase64String(memoryStream.ToArray());

Thanks, how can i have output as Hex and not base64string?

You can try Encoding.Default.GetString(memoryStream.ToArray())
