C# use of unassigned variable error

Solution 1

In this case the instance Func will be created/initialized only when the construction is done, but you are invoking a method of the instance Func before its construction through Fun.getName(),getSexo etc .

I am not sure what you are trying to do here. Looks like you are confused with the constructor overrides available in the 'Funcinario' class

It should be something like this

private void button1_Click(object sender, EventArgs e)
{
    Funcionario Func = new Funcionario(); // 
    string name = Func.getName(); //data type selected only for explanation
    string sex = Func.getSexo(); // data type selected only for explanation
}

namespace Zoo
{
    public partial class FuncionarioForm : Form
    {
        List<funcionario> Lfunc;
        List<animal> LAnimal;
        
        public FuncionarioForm()
        {
            InitializeComponent();
            Lfunc = new List<funcionario>();
            LAnimal = new List<animal>();
        }
 
        private void AdicionarFuncionario_Load(object sender, EventArgs e)
        {
 
        }         
 
        private void Refresh()
        {
            listBox1.Items.Clear();
            foreach (Funcionario F in Lfunc)
                listBox1.Items.Add(F.ToString());
            listBox1.Items.Add("----------");
            foreach (Animal A in LAnimal)
                listBox1.Items.Add(A.ToString());
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
 

            Funcionario Func = new Funcionario(Func.getNome(),
                                               Func.getSexo(),
                                               Func.getDataNascimento(),
                                               Func.getBi(),
                                               Func.getTelefone(),
                                               Func.getMorada(),
                                               Func.getEmail());
 
            Lfunc.Add(Func);
            Refresh(); 
        }

This is all code in this part, but i have a class Funcionario with a constructor, and now i want to add the data of Funcionario(employer) that is written in the textbox´s to the listbox and the list!!

You can use the 'Improve Question' link to edit your question or to post more code. Have a look at the solution it will help you to get going with the problem.

ouch - I suspect the compiler is seeing 'Func.getNome() .... ' for example, but, at that stage, Func doesnt yet exist, becuase of the Funcionario Func = new Functionario ... This all being said, I agree with jibesh .. what exactely are you trying to do, becuase Im not sure thats the way to go about it !
