c# - Start a process using System.Diagnostics.Process.Start -

i trying execute file stored under program files. program called command prompt, , output information while running. want capture output.

the code below solves half of job: program executed, , console pops showing output in console, cannot capture output:

processstartinfo start = new processstartinfo(); start.workingdirectory = directory; start.filename = filename; start.arguments = arguments; //start.useshellexecute = false; //start.redirectstandardoutput = true;  using (process process = process.start(start)) {    // code } 

now using code below capture output:

processstartinfo start = new processstartinfo(); start.workingdirectory = directory; start.filename = filename; start.arguments = arguments; start.useshellexecute = false; start.redirectstandardoutput = true;  using (process process = process.start(start)) {    using (streamreader reader = process.standardoutput)    {       string result = reader.readtoend();       console.write(result);    } } 

the program crashes in line execute start command error "the system cannot find file specified"

what don't is, first part of program works, not second.

i have search lot on topic, , there many suggestions have not been able find 1 solves issue.

i using .net 3.5 program prefers due compatibility other parts of program.
