I am Configuration A Search button of my Client Form and I have a Problems with a Variable


Hi Guys, I'm a Rookie in this and I'm doing a Small Final Degree Project on a Medical Office.

private void btnbuscar_Click_1(object sender, EventArgs e)
        BuscarUsuario bc = new BuscarUsuario();
        if (bc.ClienteSelecionado != null)
            txtnombre.Text = bc.ClienteSelecionado.nombre;
            txtapellido.Text = bc.ClienteSelecionado.apellido;
            txtiduser.Text = bc.ClienteSelecionado.user;
            txtpass.Text = bc.ClienteSelecionado.contraseña;
            txttel.Text = bc.ClienteSelecionado.tel;
            txtpais.Text = bc.ClienteSelecionado.pais;
            txtsexo.Text = bc.ClienteSelecionado.sexo;
            txtcedula.Text = bc.ClienteSelecionado.cedula;
            txtedad.Text = Ibc.ClienteSelecionado.edad;
            txtdir.Text = bc.ClienteSelecionado.dir;

This is the code in the chain txtedad I get an error saying that you can not convert an int in String iplicitamente, I need to know what I have to put, I hope, that you can help me, any help would greatly appreciate it

Explicitly you can convert an integer to a string, for example:

txtedad.Text = bc.ClienteSelecionado.edad.ToString();

but if you do not have a value there it will generate another error. Check if all of the SearchUser properties return value to you,

You can convert it like this (Both work):

txtedad.Text = bc.ClienteSelecionado.edad.ToString();

txtedad.Text = Convert.ToString(bc.ClienteSelecionado.edad);

You can also check the documentation of the Convert Class , so you can look at all the types of data you can convert.

The Text property of the Text boxes receives String, so you must explicitly convert the int to String so that you can place it in the Text property.

Alternative 1:

txtedad.Text = Ibc.ClienteSelecionado.edad.ToString(); 

ToString (), converts Ibc.ClientSelecionado.dad to its equivalent in string. This can generate an exception of type NullReferenceException if the value of age is null

Alternative 2:

txtedad.Text = Convert.ToString(Ibc.ClienteSelecionado.edad); 

If the value of Ibc.ClienteSelecionado.dad is null, it will not generate an error but it will show null.

Alternative 3:

txtedad.Text = (String)Ibc.ClienteSelecionado.edad;  

(String) here we apply a cast in runtime.
