Luk*_*son 2 .net invoke visual-c++ winforms
有没有人有学习资源的链接使用Invoke?
我正在努力学习,但我看到的所有例子都无法适应我的目的.
你尝试过MSDN Control.Invoke吗?
我刚刚编写了一个WinForm应用程序来演示Control.Invoke.创建表单时,在后台线程上启动一些工作.完成该工作后,更新标签中的状态.
public Form1()
{
InitializeComponent();
//Do some work on a new thread
Thread backgroundThread = new Thread(BackgroundWork);
backgroundThread.Start();
}
private void BackgroundWork()
{
int counter = 0;
while (counter < 5)
{
counter++;
Thread.Sleep(50);
}
DoWorkOnUI();
}
private void DoWorkOnUI()
{
MethodInvoker methodInvokerDelegate = delegate()
{ label1.Text = "Updated From UI"; };
//This will be true if Current thread is not UI thread.
if (this.InvokeRequired)
this.Invoke(methodInvokerDelegate);
else
methodInvokerDelegate();
}
