Here is what is expected of enquirers:
1. TRY first what you want to do!
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.
Members will be more than happy to help like this.

then use this

C#

private string[] ValArray;
private void Form1_Load(object sender, System.EventArgs e)
{
        // set value for ValArray

	ListBox1.Items.AddRange(ValArray);
}
private void TextBox1_TextChanged(System.Object sender, System.EventArgs e)
{
        if (TextBox1.Text == string.Empty){
                ListBox1.Items.AddRange(ValArray);
                return;
        }

	ListBox1.Items.Clear();
	foreach (string item in ValArray) {
		if (item.StartsWith(TextBox1.Text)) {
			ListBox1.Items.Add(item);
		}

	}
}

In the question it is mentioned that when first character is written then all names starting with that character shall be shown in the TextBox. Since, TextBox can not show multiple names, ComboBox can be used for this purpose, by appropriately setting the DataSource, DropDownStyle, AutoCompleteSource and AutoCompleteMode properties as shown below:

C#

ListBox listBox1 = new ListBox();
List<string> names = new List<string>() {
"Mike", "Antonio","Mark",
"Jackie", "Bruss","Alonso"
};
BindingSource bindingSource1 = new BindingSource();
bindingSource1.DataSource = names;

ComboBox comboBox1 = new ComboBox();
comboBox1.Dock = DockStyle.Bottom;
comboBox1.DataSource = bindingSource1;
comboBox1.DropDownStyle = ComboBoxStyle.DropDown;
comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;
comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

listBox1.Dock = DockStyle.Fill;
listBox1.DataSource = bindingSource1;

Controls.Add(comboBox1);
Controls.Add(listBox1);

To run the above sample, create a Windows Forms project in Visual Studio, double click on Form1 in the designer, which opens the code file, paste the above code in the Load event of Form1 and run the application.
