winforms - Having trouble getting multiple command line arguments to run in windows forms -

this has been bugging me whole weekend...i'm bit new @ please bear me.

i trying windows form button execute command line arguments passing not working. stays @ working directory...

private void convert_click(object sender, eventargs e) {         string safefile = @textbox2.text;         string safepass = @textbox3.text;         string safedir = @textbox4.text;          process test = new process();         test.startinfo.filename = "cmd.exe";         test.startinfo.useshellexecute = false;         test.startinfo.workingdirectory = @safedir;         test.startinfo.arguments = "sqltosafe.exe" + @safefile + "-password" + @safepass;         test.startinfo.redirectstandardoutput = true;         test.start();         textbox1.text = test.standardoutput.readtoend();     } 

the application supposed to:

1) 1 "convert" button clicke, grab location of .exe located.

2)execute upon .exe command-line arguments such as:

c:\safetosql\safetosql.exe (location of .safe file) -password (password)

i've been searching on web figure out how work no avail. think simple solution , maybe i'm n00b @ working on getting better.

thank reading , hope can provide input on should figuring out.

it looks failed add spaces , quotation marks command-line arguments.

test.startinfo.arguments = "sqltosafe.exe" + @safefile + "-password" + @safepass; 

should be:

test.startinfo.arguments = "sqltosafe.exe \"" + safefile + "\" -password \"" + safepass + "\""; 

or using format string instead of concatenation, clearer , doesn't create intermediate strings:

test.startinfo.arguments = string.format("sqltosafe.exe \"{0}\" -password \"{1}\"", safefile, safepass); 

the reason need quotation marks user-supplied values may contain spaces , spaces deliminate command-line parameters.

you should validate user-supplied strings make sure @ least not empty.
