How do I force Process.Start() to complete before proceeding?

Question

I'm creating a console app to process a file and then move it to a 'processed' folder. The main console app calls another app using Process.Start(). This secondary app actually does the work of bulk inserting data into a database. Once the bulk insert is complete, the main app will move the file to another folder and then move on to additional tasks.

In the main app, how do I prevent the code from continuing until the secondary app finishes? I really need to have the first process finish before moving on to the next step.

Thanks!

Answer 1

使用此方法：

process.WaitForExit();

Answer 2

您可以使用WaitForExit（） Methode

Answer 3

You might try:

Process.Start(...).WaitForExit();

Presuming you are using ProcessStartInfo, you might write it more like this:

var psi = new ProcessStartInfo();
psi.FileName = "SecondProcess.exe";
psi.Arguments = "arg1 arg2";
var process = Process.Start(psi);
if(process != null) process.WaitForExit();

Answer 5

在运行下一次迭代之前调用Process.WaitForExit（） 。
