Hi,

I was wondering if there is a CLI equivalent to using the this keyword
to overload constructors. You know where you would do something like

MyClass() : this("something")
{

}

MyClass(String name)
{

}

I can't seem to figure it out.

Thanks in advance

Constructor chaining isn't permitted in C++, it would violate object
lifetime rules. In .NET, an object is alive before the first user code in
any constructor starts running. In C++, the object is constructed
piecemeal, and each subobject becomes alive when its constructor starts.
Being able to call a different constructor, would imply the object is born
twice, which isn't allowed. Why this restriction applies to ref classes,
which follow .NET lifetime rules, I don't know. But, you can certainly have
a reusable helper function called from more than one constructor (you can't
reuse base and member initialization expressions though).
