需要搭建一个可以监控报告生成的CS(WinForm)工具,即CS不断Run,执行获取数据生成报告,经过研究和实践,选择了使用"WinForm多线程编程"的解决方案.当然参考了园中相关文章自己搞的一个Demo.
PS:由于报告生成非常耗费资源,使用单线程编程模式, 监控信息根本无法信息无法及时在RichText显示.
public partial class Form1 : Form
{ private CancellationTokenSource _cts; private int testNum = ; public Form1()
{
InitializeComponent(); } private void CreateRPT(CancellationToken ct)
{
while (true)
{
if (ct.IsCancellationRequested)
{
break;
}
//Invoke方法用于获得创建lbl_Status的线程所在的上下文
this.Invoke(new Action(() => richTextBox1.Text = testNum.ToString()));
testNum += ;
Thread.Sleep();
}
} private void btn_Count_Click(object sender, EventArgs e)
{
_cts = new CancellationTokenSource();
ThreadPool.QueueUserWorkItem(state => CreateRPT( _cts.Token ));
} private void btn_Cancel_Click(object sender, EventArgs e)
{
if (_cts != null)
_cts.Cancel();
} }
又看到一个风格
private void CreateRPT(CancellationToken ct)
{
while (true)
{
if (ct.IsCancellationRequested)
{
break;
}
//Invoke方法用于获得创建lbl_Status的线程所在的上下文
//this.Invoke(new Action(() => richTextBox1.Text = testNum.ToString()));
ViewMsg(testNum.ToString());
testNum += ;
Thread.Sleep();
}
} private void ViewMsg(string msg)
{ /* control.Invoke(new SetControlTextDelegate((ct, v) => { ct.Text = v; }), new object[] { control, value });
=>
control.Invoke(new Action<Control, string>((ct, v) => { ct.Text = v; }), new object[] { control, value }); */
this.richTextBox1.Invoke(new Action<RichTextBox, string>((ct, v) => { ct.AppendText(v); ct.Refresh(); }),new object[] { this.richTextBox1, msg });
this.richTextBox1.Invoke(new Action<string>((v) => { this.richTextBox1.AppendText(v); this.richTextBox1.Refresh(); }),msg);
}
