Reading a Text File and inserting the data into a Datagrid

public class MyDataObject
{
public string FirstName {get; set; }
public string LastName {get; set; }
}

using (System.IO.StreamReader sr = new System.IO.StreamReader("MyFileName"))
{
List<mydataobject> myList = new List<mydataobject>();
//Do your own reading in logic here, I will do a basic example assuming that
//the first and last names are comma separated, and each entry is on a new line
string[] names = sr.ReadToEnd().split('\n');
foreach (string s in names)
{
string[] values = s.split(',');
myList.Add(new MyDataObject { FirstName = values[0], LastName = values[1] });
}
//Now set your data grid's datasource to myList and call the DataBind() method and you are good to go!
