那数组存入application，再利用循环读出来

private void Button2_Click(object sender, System.EventArgs e)
{
string[] a=new string[2];
a[0]="aa";
a[1]="bb";
Application.Add("a",a);//将值赋给 Application["a"]
}

private void Button3_Click(object sender, System.EventArgs e)
{
this.ListBox1.Items.Clear();//清除列表里的值
string[] b=(string[])Application["a"];//将值赋给数组 b
for (int i=0;i<b.Length;i )
{
this.ListBox1.Items.Add(b[i]);
}
}
