如果我只想运行一次流程(即流程完成后关闭表单),这将非常有效
但是,我需要允许用户重新运行相同的进程或运行新的进程,因此我添加了一个清除按钮,清除各种控件等
我遇到的问题是,在单击“清除”按钮后,我想再次单击“运行”按钮而不关闭该按钮,然后运行sMAsterBAT文件(CMD)
StandardOutputHandler似乎包含了上一次运行的内容以及新运行的内容,从而在我的CMDpanel中产生了重复的标签
这是否存储在某种缓冲区中?如果是,如何清除它以允许重新运行
请有人解释一下为什么会发生这种情况,以及如何解决它 和工作中为我修好的人谈过。太容易了,哈哈
private void ClearBTN_Click(object sender, EventArgs e)
{
CMDpanel.Controls.Clear();
this.process.CancelOutputRead();
this.process.Close();
this.process.Refresh();
this.process = new Process(); // this line resolved my issue!!
}
}没有人知道或能够提供帮助???绝对没有建议?或者回答为什么会发生?????
