从另一个表单访问属性

Question

I have a form with some elements in it. I want to access the data from that form in my main one. I tried doing the following:

private void button1_Click(object sender, EventArgs e)
        {
            Properties.Settings.Default.emailServer = textBox1.Text;
            Properties.Settings.Default.emailServerPort = (int)numericUpDown1.Value;
            Properties.Settings.Default.emailServerSsl = (radioButton1.Checked == true) ? true : false;
            Properties.Settings.Default.Save();
            this.Close();
        }

I can load it perfectly fine in the existing form using this code:

private void EmailSettings_Load(object sender, EventArgs e)
        {
            textBox1.Text = Properties.Settings.Default.emailServer;
            numericUpDown1.Value = Properties.Settings.Default.emailServerPort;
            if (Properties.Settings.Default.emailServerSsl == true)
            {
                radioButton1.Checked = true;
            }
            else
            {
                radioButton1.Checked = false;
            }
        }

HOWEVER, my issue is that I can't access Properties from my main form. So I still can't access the data from that form. How can I access the data either from properties in my main form or from another form?

Answer 1

You have changed settings .You can access to settings from every where from your project . Here you have set settings in form2 then you can access it from main form

 var setting=Properties.Settings.Default.YourSetting;

If namespace in form2 and main form are different You must write like

var setting=namespaceOfForm2.Properties.Settings.Default.YourSetting;

Also you can below solution

On the second form create a property

public yourType yourProperty { get;set;}

Store your data to it

yourProperty=yourData;
// set this.DialogResult property if you successfully     stored data
this.DialogResult=DialogResult.OK;

And from main form get it

Form2 f=new Form2();
if(f.ShowDialog==DialogResult.OK)
{
    var yourData=f.yourProperty;
}

Example:

On form2:

public string Name { get; set;}
public void methodThatYouSetData()
{
    Name=txtbx.Text;
    this.DialogResult=DialogResult.OK;  
}

On main form:

Form2 f=new Form2();
if(f.ShowDialog==DialogResult.OK)
{
    string Name=f.Name;
}
