c# - Zero-pad a date string without converting to a different type -


i have several dates in string form. want ensure have format 09/08/2012 if come in 9/8/2012.

i know convert them datetime objects, strings, , format them way. question comes curiosity, not necessity.
want know if there's way without data transformations. guess if it's possible use string.format() method.

is possible apply zero-padded date format string without changing type part of process?

this easy do.

  1. split string on /.
  2. left-pad each section 2 digits, prepending '0' needed.
  3. join string parts together

code:

var x = "9/7/2017"; var parts = x     .split('/')                         //  <-- step 1     .select(y => y.padleft(2, '0'));    //  <-- step 2 var z = string.join("/", parts);        //  <-- step 3  debug.writeline(z);   // prints 09/07/2017

as can see code just complicated enough take minute read , understand. it's clearer parse date datetime, reformat desired format.

var x = "9/7/2017"; var z = datetime.parse(x).tostring("mm/dd/yyyy");

that's much easier follow.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
