txtState.Invoke(new Action(() => { txtState.Text = "要显示的内容"; }));

txt2.Text = "txt2";
txt3.Text = "txt3";
txt4.Text = "txt4";
}));

{
if (!this.IsDisposed)
{
if (this.labState_Now.InvokeRequired)
{
SetTextLabStateNowCallBack stcb = new SetTextLabStateNowCallBack(SetLabState_NowText);
this.Invoke(stcb, new object[] { runInfo });
}
else
{
this.labState_Now.Text = runInfo + " " + DateTime.Now;
}
