如何通过线程为标签设置值？

Question

此代码给出错误'对象引用未设置为对象的实例'。

public partial class _Default : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     _Default obj = new _Default(); 
     Thread thread = new Thread(new ThreadStart(obj.ThreadStart)); 
     thread.Start(); 

    } 
    public void ThreadStart() 
    { 
     show(); 
    } 
    private void show() 
    { 
     lblget.Text = "hi"; 
    } 

Answer 1

无需创建_Default的实例。

protected void Page_Load(object sender, EventArgs e) 
    { 
     Thread thread = new Thread(show); 
     thread.Start(); 
    } 
    private void show() 
    { 
     lblget.Text = "hi"; 
    }
