我是c#的新手,我对使用WinForm完成一个包含表单接收的参数的批处理文件,执行批处理并创建特定文件表示怀疑.
是)我有的：
WinForm – > 2个字符串变量(ip和user)
批处理文件 – >使用个性化图标在桌面上创建.rdp文件及其快捷方式(手动启动时批处理工作)
我的问题是代码第一次工作,但如果我尝试更改变量,进程不会运行,文件不会被新信息覆盖,我有一个错误说我没有访问权限.
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());
}
}

如果文件不存在,如果存在覆盖它,我正在考虑启动进程代码,但我不知道如何从这里开始.
解决方法:
我建议尝试仅在C#中完成您的任务,这里有一些代码和我的评论,以便让您前进.通过在方法调用周围添加try / catch块,让我们知道它导致的异常.
