Cross-thread operation not valid: how to access controls from another thread in C# WinForms

Hello everyone! I'm a beginner in C# and WinForms, and I'm stuck on a multithreading problem. I'm writing an application that loads data from the internet and displays it in a ListBox. To prevent the interface from freezing, I run the loading in a separate thread via Task.Run. Here's simplified code: ```csharp private void buttonStart_Click(object sender, EventArgs e) { Task.Run(() => LoadData()); } private void LoadData() { for (int i = 0; i < 10; i++) { // Simulating data loading Thread.Sleep(1000); // Trying to add an item to ListBox listBoxResult.Items.Add("Element " + i); } } ``` When running, on the line `listBoxResult.Items.Add(...)` an exception is thrown: "Cross-thread operation not valid: Control 'listBoxResult' accessed from a thread other than the thread it was created on."
