Ok, here is the code:
This are code snippets. I didn't tried it in this short form, only with the
whole framework.

[WebMethod]
public byte[] TestWsHugeReturnConfigurable(float sizeInMegabyte)

    int size = Convert.ToInt32(sizeInMegabyte * 1024f * 1024f);
    byte[] myByteArray = new byte[size];
    return myByteArray;    
}
