2x forms.
1x class.
Any suggestions as to why this doesn't show the name/age in form 2?
Code below:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Form_Class_Test
{
class Variables
{
private string name;
private int age;
public Variables()
{
}
public string Name
{
get { return this.name; }
set { this.name = value; }
}
public int Age
{
get { return this.age; }
set { this.age = value; }
}
}
}
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace Form_Class_Test
{
public partial class Form1 : Form
{
Variables V1 = new Variables();
Form2 F2 = new Form2();
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
V1.Name = textBox1.Text;
V1.Age = int.Parse(textBox2.Text);
this.Hide();
F2.ShowDialog();
}
private void button2_Click(object sender, EventArgs e)
{
}
private void button3_Click(object sender, EventArgs e)
{
}
}
}
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace Form_Class_Test
{
public partial class Form2 : Form
{
Variables V1 = new Variables();
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{
label1.Text = V1.Name;
label2.Text = V1.Age.ToString();
}
private void label1_Click(object sender, EventArgs e)
{
}
}
}

Just to add, I can do this via constructor but not via properties as it happens.
EDIT: Using static variables within the variable class fixed my issue; due to the fact I was only wanting to refer to single instances of an object; this turned out perfectly.
I'm aware of the being thread-unsafe; I just don't know how to lock the thread.

You use one instance of Variable class in Form1 and other instance in Form2.
You should pass same instance for it to work.
Like:
Variables V1 = new Variables();
Form2 F2;
public Form1()
{
InitializeComponent();
F2 = new Form2(V1);
}
public partial class Form2 : Form
{
Variables V1;
public Form2(Variables v)
{
InitializeComponent();
V1 = v;
}
}

That is basically the same problem you had before where you insisted, that you were using the same instance, right?
