Question

我正在从wpf项目转移到winforms项目的方法。

除了这一部分之外的所有内容都没有问题：

private void ServerProcErrorDataReceived(object sender, DataReceivedEventArgs e)
{
  // You have to do this through the Dispatcher because this method is called by a different Thread
  Dispatcher.Invoke(new Action(() =>
  {
    richTextBox_Console.Text += e.Data + Environment.NewLine;
    richTextBox_Console.SelectionStart = richTextBox_Console.Text.Length;
    richTextBox_Console.ScrollToCaret();
    ParseServerInput(e.Data);
  }));
}

我不知道如何将Dispatcher转换为winforms。

任何人都可以帮助我吗？

您应该使用Invoke替换Dispatcher。

private void ServerProcErrorDataReceived(object sender, DataReceivedEventArgs e)
{
    if (richTextBox_Console.InvokeRequired)
    {
        richTextBox_Console.Invoke((MethodInvoker)delegate
        {
            ServerProcErrorDataReceived(sender, e);
        });
    }
    else
    {
        richTextBox_Console.Text += e.Data + Environment.NewLine;
        richTextBox_Console.SelectionStart = richTextBox_Console.Text.Length;
        richTextBox_Console.ScrollToCaret();
        ParseServerInput(e.Data);
    }
}
