C# 从进程中获取返回值

Get return value from process

提问by Hany

Hi I am trying to do the following: I have a process which can take parameters (digits) and return the sum of these numbers

嗨，我正在尝试执行以下操作：我有一个可以接受参数（数字）并返回这些数字之和的过程

Process P = Process.Start(sPhysicalFilePath, Param);
                int result = P.ExitCode;

I get the return value from "ExitCode" the problem is: the program sometimes finishes his work before the process so when the program reaches this line

我从“ExitCode”得到返回值，问题是：程序有时会在进程之前完成他的工作，所以当程序到达这一行时

int result = P.ExitCode;

I got an exception .. my question is how to wait this process until it finishes its work sorry I forget to say that's I am working with C# language

我有一个例外..我的问题是如何等待这个过程直到它完成它的工作对不起我忘记说我正在使用 C# 语言
