Profile 1
Profile 2

我想在表单加载时选择Profile 2.我该怎么做?

I want to have Profile 2 selected when the form loads. How do I do this?

推荐答案

设置ListBox.SelectedIndex 属性.forms.form.shown.aspx" rel="noreferrer">Form.Shown 事件.
例如:

Set the ListBox.SelectedIndex property in the Form.Shown event.
For example:

public Form1()
{
    InitializeComponent();

    // Adding the event handler in the constructor
    this.Shown += new EventHandler(Form1_Shown);
}    

private void Form1_Shown(object sender, EventArgs e)
{
    myListBox.SelectedIndex = 1;
}
