I previously posted about Cross-thread control access using Control.Invoke() method. But it was using Deletes. Today I tried using anonymous methods, but it wasn’t worked. Later I resolved it using Action()(or you can use MethodInvoker()) system delegate.

if (this.prgInfo.InvokeRequired)
{
    this.prgInfo.Invoke(new Action(delegate()
    {
	//Code
    }));
}

And nowadays I am working with developers, who loves to write lamda expressions every where And this is the lamda alternative.

if (this.prgInfo.InvokeRequired)
{
    this.prgInfo.Invoke(new Action(() =>
    {
	//Code
    }));
}

You can also use the following method.

if (this.prgInfo.InvokeRequired)
{
    this.prgInfo.Invoke((Action)(() =>
    {
	//Code
    }));
}

Happy coding
