How to get and set variables from console application
问题
我有一个.NET应用程序，它使用以下代码调用一个.NET Core应用程序：
Process p = new Process();
var startInfo = p.StartInfo;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.FileName = "myDotNetCoreApp.exe";
startInfo.Arguments = arguments;
startInfo.CreateNoWindow = true;
p.OutputDataReceived += P_OutputDataReceived;
p.Start();
p.BeginOutputReadLine();
p.WaitForExit();
正如你所看到的，我在控制台应用程序的Main方法中设置了字符串（arguments），并像这样获取它：
static void Main(string[] args)
{
var inputCommands = args[0].Split(",");
// ...
}
此外，我捕获了Console.WriteLine()的“事件”并执行一些操作。我在控制台应用程序中有一个方法，它返回bool类型。现在我需要从.NET应用程序中知道该方法返回了什么结果。我可以这样做：Console.WriteLine("Method returned true")，但这种方法不太符合我的需求。是否有其他方法可以实现这个目标？
英文:
I have a .net app that calls a .net core app using the following code:
Process p = new Process();
var startInfo = p.StartInfo;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.FileName = "myDotNetCoreApp.exe";
startInfo.Arguments = arguments;
startInfo.CreateNoWindow = true;
p.OutputDataReceived += P_OutputDataReceived;
p.Start();
p.BeginOutputReadLine();
p.WaitForExit();
As you can see I'm setting strings (argument) on the Main method of console app and I'm getting it like this:
static void Main(string[] args)
{
var inputCommands = args[0].Split(",");
...
}
Also, I catch Console.WriteLine() "event" and doing some actions. I have a method in the console app and it returns bool type. Now from the .net app, I need to know what result was returned from the method. I could do it like Console.WriteLine("Method returned true") but it doesn't like me. Is there another way to do this?

从 @Cid 的评论中：
在你的 myDotNetCoreApp 应用程序中使用以下代码关闭应用程序：
System.Environment.Exit(0);
0 表示你的应用程序成功关闭。
然后使用以下代码从 myDotNetCoreApp 获取信息：
Process p = new Process();
var startInfo = p.StartInfo;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.FileName = "myDotNetCoreApp.exe";
startInfo.Arguments = arguments;
startInfo.CreateNoWindow = true;
p.OutputDataReceived += P_OutputDataReceived;
p.Start();
p.BeginOutputReadLine();
p.WaitForExit();
if (p.ExitCode == 0){
// 做一些操作...
}
英文:
From @Cid's comment:
In your myDotNetCoreApp app close your app using:
System.Environment.Exit(0)
0 means your app closed successfully
Then use this to get info from myDotNetCoreApp
Process p = new Process();
var startInfo = p.StartInfo;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.FileName = "myDotNetCoreApp.exe";
startInfo.Arguments = arguments;
startInfo.CreateNoWindow = true;
p.OutputDataReceived += P_OutputDataReceived;
p.Start();
p.BeginOutputReadLine();
p.WaitForExit();
if(p.ExitCode==0){
//Do some...
}
