Calling via command prompt from ASP.NET
A reader is trying to find a way to call a program using the command prompt from ASP.NET.
This question comes up from time to time.It is one we have answered before.
The code is as follows:
// Get a file name relative to the current Web app.
string file = Server.MapPath(@"binMyApp.exe");
ProcessStartInfo info = new ProcessStartInfo(file, "Kzu otherargs");
// Redirect output so we can read it.
info.RedirectStandardOutput = true;
// To redirect, we must not use shell execute.
info.UseShellExecute = false;
// Create and execute the process.
Process p = Process.Start(info);
p.Start();
// Send whatever was returned through the output to the client.
Response.Write(p.StandardOutput.ReadToEnd());
Note that the ASP.NET worker process needs to have permissions to access the external application. The most simple way to ensure this is to place it under the bin folder.
