I'm looking to do this in C#.
public struct Structure1
{ string string1 ; //Can be set dynamically
public string[] stringArr; //Needs to be set dynamically
}
In general, how should one initialize an array dynamically if need be? In simplest of terms, I'm trying to achieve this in C#:
int[] array;
for (int i=0; i < 10; i++)
array[i] = i;
Another example:
string[] array1;
for (int i=0; i < DynamicValue; i++)
array1[i] = "SomeValue";
First off, your code will almost work:
int[] array = new int[10]; // This is the only line that needs changing
for (int i=0; i < 10; i++)
array[i] = i;
You could potentially initialize your arrays within your struct by adding a custom constructor, and then initialize it calling the constructor when you create the struct. This would be required with a class.
That being said, I'd strongly recommend using a class here and not a struct. Mutable structs are a bad idea - and structs containing reference types are also a very bad idea.
Edit:
If you're trying to make a collection where the length is dynamic, you can use List<T> instead of an array:
List<int> list = new List<int>();
for (int i=0; i < 10; i++)
list.Add(i);
// To show usage...
Console.WriteLine("List has {0} elements. 4th == {1}", list.Count, list[3]);
List<T> instead of an array.int[] arr = Enumerable.Range(0, 10).ToArray();
update
int x=10;
int[] arr = Enumerable.Range(0, x).ToArray();
// IF you are going to use a struct
public struct Structure1
{
readonly string String1;
readonly string[] stringArr;
readonly List<string> myList;
public Structure1(string String1)
{
// all fields must be initialized or assigned in the
// constructor
// readonly members can only be initialized or assigned
// in the constructor
this.String1 = String1
// initialize stringArr - this will also make the array
// a fixed length array as it cannot be changed; however
// the contents of each element can be changed
stringArr = new string[] {};
// if you use a List<string> instead of array, you can
// initialize myList and add items to it via a public setter
myList = new List<string>();
}
public List<string> StructList
{
// you can alter the contents and size of the list
get { return myList;}
}
}
