Cannot use 'this' in member initializer?

Question

Is this legal? Does it contain a hidden bug or flaw? Visual studio does not give any errors or warnings but ReSharper does:

/// 

/// immutable         


        

Answer 1

Your constructor will loop forever, until it pops the stack. This is because it keeps calling itself recursively. Try splitting it up:

public Pair(TValue1 value1, TValue2 value2)
    : this(value1, value2, () => toStringFunc(this)) { }

public Pair(TValue1 value1, TValue2 value2, Func, String> toStringFunc)
    { /* some actual logic */ }
