How to store textboxes into an array during runtime

The Situation is like this: I have multiple textboxes. On the occurrence of textChanged event the textbox should be stored in the array so that I can use it in further functions. 

private void txt_TextChanged(object sender, TextChangedEventArgs e)
    {
        TextBox t;
        t = (TextBox)sender;
    }

Now I have the textbox which was responsible for the event. Now I have to store this and more to come in an array so that these can be accessed elsewhere in another function.

Assuming you want to store the text from the TextBoxes, you can use a dictionary like this:

private Dictionary<string, string> dictionary = new Dictionary<string, string>();

private void txt_TextChanged(object sender, TextChangedEventArgs e)
{
    TextBox textBox = (TextBox)sender;
    string key = textBox.Name;
    string value = textBox.Text;
    if (!dictionary.ContainsKey(key))
    {
        dictionary.Add(key, value);
    }
    else
    {
        dictionary[key] = value;
    }
}

Description

I dont know why you need to store your TextBoxes in a List or Array but you can use the generic List for that.

Represents a strongly typed list of objects that can be accessed by index. Provides methods to search, sort, and manipulate lists.

Sample

List<TextBox> myTextBoxes = new List<TextBox>();
// Add a TextBox
myTextBoxes.Add(myTextBox);
// get a TextBox by Name
TextBox t = myTextBoxes.Where(x => x.Name == "TextBoxName").FirstOrDefault();

You could throw it in a list if ya like. Not sure why you would really want to do this though...

List<TextBox> txtbxList = new List<TextBox>();

private void txt_TextChanged(object sender, TextChangedEventArgs e)
    {
        TextBox t;
        t = (TextBox)sender;
        txtbxList.Add(t);
    }
