public partial class Default2 : System.Web.UI.Page
{
private static string abc;
protected void Page_Load(object sender, EventArgs e)
{
abc = "原始 ";
}
protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = abc;
}
protected void Button2_Click(object sender, EventArgs e)
{
abc = "改变 ";
Label1.Text = abc;
}
}

[解决办法]
protected void Page_Load(object sender, EventArgs e)
{
if(!page.IsPostback)
{
abc = "原始 ";
}
}
