WPF uses the Process.Start () method to start an EXE file under a specified path and pass parameter receive parameters

A requirement was encountered in development: WPF program A starts WPF program B and passes parameters, and WPF program B receives parameters and processes them.

How to achieve such a demand, there are already a lot of articles on the network to describe the problem, here to make a record.

First, start WPF client B with the following code:

        Private void Actionstartclientexcute ()        {            var"exe location ";             New Process ();             = address;             " arg1 arg2 " ;             true ;            Process. Start ();        }

Add the following code to the receiving client:

Define a Mainapp class, which must have a main (string[] args) function with parameters, and set the Mainapp class with the main function as the Startup object.

Select the current project, and then right-click the properties----application panel, set the Startup object.

Externally passed parameters are in string[] args, for example, the passed parameter is the string "arg1 arg2", then the content of args is args[0]= "arg1", args[1]= " Arg2 ", where each array element is separated by a space.

There should be a App.xaml and a App.xaml.cs file in the project. They inherit to the application class, set the program's start page in App.xaml startupuri= "Window.xaml", which is our original program interface.

Here we need to instantiate the app class at the end of the main function: The Initapp method in the code.

     Public classMainapp {[STAThread] Public Static voidMain (string[] args) {            if(Args! =NULL&& args. Length = =2)            {                stringarg1= args[0].                Trim (); stringArg2= args[1].            Trim ();        } Initapp (); }         Public Static voidInitapp () {app app=NewApp (); App.            InitializeComponent (); App.        Run (); }    }

This will enable WPF program A to open WPF program B and pass parameters to this requirement!!!
