Constructor cannot call itself c#

Question

Constructor \"Delay.vkMessages.vkMessages(string, System.DateTime, string, bool, string)\" cannot call itself.I have another class, copy of this class, but it works(I can add co

Answer 1

Remove the last parameter:

public vkMessages(string kto, DateTime date_time,
                  string text, bool read_state,string in_or_out)
    : this(kto, date_time, text, read_state)
{
    InOrOut = in_or_out;
}

That said, your logic is skewed, it should be the other way round (i.e. this constructor should do all the work and the other constructor should call this one:

public vkMessages(string kto, DateTime date_time, string text, bool read_state)
    : this(kto, date_time, text, read_state, false) { }

public vkMessages(string kto, DateTime date_time,
                  string text, bool read_state,string in_or_out)
{
    InOrOut = in_or_out;
    Kto = kto;
    Date_Time = date_time;
    TexT = text;
    Read_State = read_state; 
}

Finally, you should fix your identifiers to conform to the .NET guidelines. In particular, a class should follow the PascalCase convention of starting with an upper-case letter.
