Fill combo by an array on a web form in c # .net

I have four variables of Long DateTime type, I want to fill combo with the help of these four values on a web page (开发者_如何转开发using c sharp), The combo should show the name of Month of corresponding datetime variable, How can ido that?

You can also use a Datatable for this purpose. Simply say,

 ddlName.DataSource = dataableName;

 ddl.DataValueField = "ColumnName";

 ddl.DataTextField = "ColumnName"; 

Store the desired Values in respective columns and simply write their names against text or value fields.

It sounds like you are trying to populate the combobox at runtime on your ASP.NET page in an unbound manner. If this is the case, you would use the following code:

yourCombo.Items.Add(date1.ToString("MMMM"));
yourCombo.Items.Add(date2.ToString("MMMM"));
yourCombo.Items.Add(date3.ToString("MMMM"));
yourCombo.Items.Add(date4.ToString("MMMM"));

This will show your four variables in the combobox with their full month name.

Action<DateTime> addItem = dateTime => 
    dropDownList.Items.Add(new ListItem(dateTime.ToString("MMMM"), dateTime.ToString("O")));

addItem(dateTime1);
addItem(dateTime2);
addItem(dateTime3);
addItem(dateTime4);

or just add a mentod

private void AddItem(DateTime dateTime)
{
    dropDownList.Items.Add(new ListItem(dateTime.ToString("MMMM"), dateTime.ToString("O")));
}

protected void Page_Load(object sender, EventArgs e)
{
    AddItem(dateTime1);
    AddItem(dateTime2);
    AddItem(dateTime3);
    AddItem(dateTime4);
}
