c# - Formatting text table in file, merging two lines per row into one -

i'm trying write information text file second row making spaces between lines

the code :

private void createdriverslist() {     streamwriter w = new streamwriter(contentdirectory + "\\" + "drivers.txt");     w.writeline("module name  display name           driver type   link date");     w.writeline("============ ====================== ============= ======================");     //declare, search, , properties in win32_systemdriver     system.management.selectquery query = new system.management.selectquery("win32_systemdriver");     system.management.managementobjectsearcher searcher = new system.management.managementobjectsearcher(query);     foreach (system.management.managementobject manageobject in searcher.get())     {         w.writeline(manageobject["name"].tostring());         w.writeline("             " + manageobject["displayname"].tostring());     }     w.close(); } 

once added line :

w.writeline("             " + manageobject["displayname"].tostring()); 

the result in text file :

module name  display name           driver type   link date ============ ====================== ============= ====================== 1394ohci              1394 ohci compliant host controller 3ware              3ware acpi              microsoft acpi driver acpiex              microsoft acpiex driver acpipagr 

before added line text file :

module name  display name           driver type   link date ============ ====================== ============= ====================== 1394ohci 3ware acpi acpiex acpipagr acpipmi 

i wanted add display name row added spaces row start under display name adding spaces in between lines.

how can solve ?

**

in end text file should :

module name  display name           driver type   link date              ============ ====================== ============= ====================== 1394ohci     1394 ohci compliant ho kernel        7/26/2012 5:26:46   3ware        3ware                  kernel        3/8/2012 10:33:45 pm   acpi         microsoft acpi driver  kernel        9/20/2012 9:09:16   acpiex       microsoft acpiex drive kernel        7/26/2012 5:25:57   acpipagr     acpi processor aggrega kernel        7/26/2012 5:27:16   acpipmi      acpi power meter drive kernel        7/26/2012 5:27:33   acpitime     acpi wake alarm driver kernel        7/26/2012 5:27:37   

and in display name row , maybe in moudle name row make sure names in 1 line full names.

for example in display name : 1394 ohci compliant ho should : 1394 ohci compliant host controller

**

module name  display name           driver type   link date ============ ====================== ============= ====================== 1394ohci     1394 ohci compliant host controller 3ware        3ware acpi         microsoft acpi driver acpiex       microsoft acpiex driver acpipagr     acpi processor aggregator driver acpipmi      acpi power meter driver 

you've called writeline twice in loop - it's adding 2 lines each item. want add one line, e.g.

w.writeline("{0} {1}", manageobject["name"], manageobject["displayname"]); 

that won't pad spaces though, need include alignment aspect in composite format string. want left padding, need negative alignment, , looks want 12 characters before space, so:

w.writeline("{0,-12} {1}", manageobject["name"], manageobject["displayname"]);
