Implement dynamically adding elements to arrays in C#

C# dynamically add elements to arrays

background:

Now we need to loop into the array, but the arrays in C# do not support dynamic addition of elements and can only create arrays of fixed size. How to solve this problem?

Referring to the online information, I personally think the solution is better: use the generic list<T>, first save the element into the list, and finally use ToArray() to convert it into an array.

Array to list< string >

string[] strArray = new string[]{str1,str2,str3};
//You can also string[] strArray = {str1,str2,str3};List&lt;string&gt; strList = new List&lt;string&gt;(strArray);

< string > to string array

List&lt;string&gt; strList = new List&lt;string&gt;();
for(int i = 0; i &lt; 3; i++)
{
    ("str"+i);//Loop to add elements}
string[] strArray = ();//strArray=[str0,str1,str2]

C# dynamically add elements using List

Arrays in C# do not support dynamic addition of elements, and can only create arrays of fixed size.

Solution: You can use List

List<string> result = new List<string>();
for (int i = 0; i < 5; i++ )
{
    (());
}

It can also be converted to array type later:

string[] strArray = ();

Attachment: Iterate over elements in List

foreach (T element in mList) 
{
     (element);
}

The above is personal experience. I hope you can give you a reference and I hope you can support me more.
