Question

I did some Google search but could not find anything. So I implemented something working with an intermediate constructor.

However, I am wondering whether it is possible to chain more than one constructor at the same time (base + this).

This is my current (simplified) code:

public BlaNode(Node Previous, Node Next) : base(Previous, Previous)
{
    this.Blas = new HashSet<BlaDiBla>();
}
public BlaNode()
    : this(null, null)
{

}
public BlaNode(Node Previous, Node Next, string Bla)
    : this(Previous, Previous)
{

}

No, you can only call one constructor at a time in a C# constructor initializer. The documentation refers to only one other constructor to call, too:

All instance constructors (…) include an invocation of another instance constructor (…). The constructor to implicitly invoke is determined by the constructor-initializer:

You can make your intermediate constructor private if you do not want any other code to call it.
