Create dynamic variable name

Question

Can we create dynamic variable in C    I know my below code is threw error and very poor coding  But this code have small logic like create dynamic variable   var name 0  for i 0 i lt 10 i      10 means grid length       name i i     var xx1 name1  var xx2 name2  var xx3 name3       Is it possible in c   Create dynamic variable in c   and change the variable name in c   and concatenate the variable name in c  like we can concatenate any control id or name       Why I need the dynamic variable name  scenario    var variablename    var variablename0 No  var variablename1 Yes  var variablename2 No           I have a gridview with multiple rows  And I need assign server side variable to every row  So I need set of variables in server side  the only I can set Text  lt    variablename rowCount  gt  for every template field   This rowCount means every grid row index    If the grid has 2 rows  Then rowCount values are 0 1 2  Now I need to change the variablename to variablename0 variablename1 variablename2 dynamically for separate row

No  That is not possible  You should use an array instead   name i    i    In this case  your name i is name i

C  is strongly typed so you can t create variables dynamically   You could use an array but a better C  way would be to use a Dictionary as follows   More on C  dictionaries here   using System  using System Collections Generic  using System Linq  using System Text  using System Threading Tasks   namespace QuickTest       class Program               static void Main string   args                        Dictionary lt string  int gt  names   new Dictionary lt string int gt                   for  int i   0  i  lt  10  i                                  names Add String Format  name 0    i ToString     i                              var xx1   names  name1                var xx2   names  name2                var xx3   names  name3

Variable names should be known at compile time  If you intend to populate those names dynamically at runtime you could use a List lt T gt    var variables   List lt Variable gt      variables Add new Variable   Name   inputStr1      variables Add new Variable   Name   inputStr2       here input string maybe any text or any list

This is not possible  it will give you a compile time error   You can use array for this type of requirement    For your Reference     http   msdn microsoft com en-us library aa288453 28v vs 71 29 aspx

try this one  user json to serialize and deserialize     using System      using System Collections Generic      using System Linq      using System Text      using System Threading Tasks      using System Web Script Serialization       namespace ConsoleApplication1              public class Program                    static void Main string   args                            object newobj   new object                   for  int i   0  i  lt  10  i                                    List lt int gt  temp   new List lt int gt                      temp Add i                   temp Add i   1                     newobj   newobj AddNewField  item     i ToString    temp ToArray                                                public static class DynamicExtention                   public static object AddNewField this object obj  string key  object value                            JavaScriptSerializer js   new JavaScriptSerializer                   string data   js Serialize obj                  string newPrametr          key           js Serialize value                  if  data Length    2                                  data   data Insert 1  newPrametr                               else                                   data   data Insert data Length-1      newPrametr                                  return js DeserializeObject data
