我是c＃的新手，我对使用WinForm使用表单接收的参数来完成批处理文件，执行批处理并创建特定文件有疑问。
我所拥有的：
WinForm-> 2个字符串变量（ip和用户）
批处理文件->在桌面上使用个性化图标创建.rdp文件及其快捷方式（该批处理在手动启动时有效）
我的问题是代码第一次起作用，但是如果我尝试更改变量，则该过程将无法运行，并且文件不会被新信息覆盖，并且出现错误，提示我没有访问权限
WinForm代码：
private void ok_Click(object sender, EventArgs e)
{
string ipText, userText, defaultFile, rdpFile;
ipText = this.ipOutput.Text;
userText = this.userOutput.Text;
defaultFile = "C:\\TerminalServer\\RDbatch.cmd";
rdpFile = "C:\\TerminalServer\\RD Arbeitsplatz.rdp";
Console.WriteLine("IP : " + ipText + "; USER : " + userText);
Process p = null;
try
{
p = new Process();
p.StartInfo.CreateNoWindow = true;
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
p.StartInfo.FileName = defaultFile;
p.StartInfo.Arguments = String.Format("{0} {1}", ipText, userText);
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.Start();
p.WaitForExit();
}
catch(Exception ex)
{
Console.WriteLine("Exception Occurred :{0},{1}", ex.Message, ex.StackTrace.ToString());
}
}

我正在考虑如果文件不存在并覆盖它，则启动流程代码，但是我不确定如何从这里开始。

我建议您尝试仅使用C＃来完成您的任务，以下是一些带有我的注释的代码，以帮助您入门。通过在方法调用周围添加try / catch块，让我们知道它导致了什么异常。
