调用自己来绕过不同的线程? C#

Invoke self to bypass different threads? C#

我已经四处寻找了大约 3 个小时,但无法使此调用起作用。我需要调用,因为调用它的是在不同的线程中并且说它不稳定。

我是这么叫的(我是这样叫的textBox1_TextChanged(null, null);):

 private void textBox1_TextChanged(object sender, EventArgs e)
 {
     if(this.InvokeRequired)
     {
        this.Invoke(this?WHAT GOES HERE, null); // I know it should be a delegate or something but I can't change this to that
     }
     else
     {
        string temp = ""; 
        temp += TextToAdd;
        textBox1.Text = "s";
     }
}

您可以使用 BeginInvoke 从其他线程更新 UI。

if (this.InvokeRequired)
{
  var action = new Action(() => textBox1.Text = "s");
  this.BeginInvoke(action);
}
