StringBuilder namevalues = new StringBuilder("");

for(int i =0; i<2; i++)
{
    if(namevalues.Length >0 )
    {
        namevalues.Append("*" + Listboxs.Items[i].ToString());
    }
    else
    {
        namevalues.Append(Listboxs.Items[i].ToString());
    }

}

Use string.Join with Cast()

var namevalues = string.Join("*", Listboxs.Items.Cast<string>().ToArray());

Since Listboxs.Items returns ListBox.ObjectCollection which implements IEnumerable interface, you can just use string.Join without for loop like;

string.Join("*", Listboxs.Items.Cast<string>());

should return

Pieter*John*Joseph
