c# - 如何将 wpf 调度程序转换为 winforms

Question

我正在将一种方法从 wpf 项目转移到我的 winforms 项目。

除此部分外的所有内容均已毫无问题地移动：

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);
  }));
}

我不知道如何转换Dispatcher为winforms。

谁能帮我吗？

您应该使用Invoke来替换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);
    }
}
