title: C# array byte[].Length property
body: <p>C# array byte[].Length property.</p>
  
  <p>byte[] buffer = new ...</p>
  
  <p>When call int i = buffer.Length; I can see get_Length() in reflector,</p>
  
  <p>What happens? Does it calculate actual length or just takes value (like property) ???</p>
