Two Dimensional Array C# -

i input user - "99211,99212,99213_1,99214,99215_3" , store in string as

string cpt = "99211,99212,99213_1,99214,99215_3"; cptarray = cpt.split(','); 

i got output

cptarray[0] = "99211" cptarray[1] = "99212" cptarray[2] = "99213_1" cptarray[3] = "99214" cptarray[4] = "99215_3" 

but output be:

cptarray[0][0] = "99211","" cptarray[1][0] = "99212","" cptarray[2][0] = "99213","1" cptarray[3][0] = "99214","" cptarray[4][0] = "99215","3" 

if need output above can use 2d array, correct approach?

according syntax provided:

 cptarray[0][0]  ...  cptarray[4][0] 

you want jagged array, not 2d one; can construct array of linq:

 var cptarray = cpt    .split(',')    .select(number => number.split('_'))    .select(items => items.length == 1 ? new string[] {items[0], ""} : items)    .toarray(); 

test

string test = string.join(environment.newline, cptarray   .select((line, index) => string.format("cptarray[{0}] = {1}",       index,      string.join(", ", line.select(item => "\"" + item + "\"")))));  console.write(test); 

output

 cptarray[0] = "99211", ""  cptarray[1] = "99212", ""  cptarray[2] = "99213", "1"  cptarray[3] = "99214", ""  cptarray[4] = "99215", "3"
