I am new to programming and I have a question. If I have two functions, one creates a text file and writes into it, while the other opens the same text file and reads from it.
The error I get is:
System.IO.IOException: 'The process cannot access the file '@.txt'
because it is being used by another process.'
I have tried setting seperate timers to each of the functions but it still does not work. I think the best way would be that the function two does not start until function one ends.
Can you help me achieve this?
Thank you very much!

Source code:
public Form1() {
InitializeComponent();
System.Timers.Timer timerButtona1 = new System.Timers.Timer();
timerButtona1.Elapsed += new ElapsedEventHandler(tickTimera1);
timerButtona1.Interval = 3003;
timerButtona1.Enabled = true;
}
private async void tickTimera1(object source, ElapsedEventArgs e) {
function1();
function2();
}
void function1() {
List<string> linki = new List<string>();
linki.Add("https://link1.net/");
linki.Add("https://link2.net/");
linki.Add("https://link3.net/");
List<string> fileNames = new List<string>();
fileNames.Add("name1");
fileNames.Add("name2");
fileNames.Add("name3");
for (int x = 0; x < fileNames.Count; x++) {
GET(linki[x], fileNames[x]);
//System.Threading.Thread.Sleep(6000);
}
}
async void GET(string link, string fileName) {
var ODGOVOR = await PRENOS_PODATKOV.GetStringAsync(link);
File.WriteAllText(@"C:Users..." + fileName + ".txt", ODGOVOR);
}
void function2() {
string originalText = File.ReadAllText(@"C:Users...fileName.txt", Encoding.Default);
dynamic modifiedText = JsonConvert.DeserializeObject(originalText);
//then i then i read from the same text files and use some data from it..
}
