Get DateTime field from table and get year, month, and day on C#

Question

I have a SQL Server table that has a DateTime field called ProductionDate . The format of this field is: 2015-06-29 00:00:00.000
I have a C# WinForm application that selects this date with this:

string productionDate = String.Empty;
var prodDate = pallets.Select(r => r.Production_Date);
if (prodDate.Count() == 1)
{
    productionDate = prodDate.First().ToString();
}

Now, this form calls a second form with this line:
EditBOL bol = new EditBOL(BOL, Batch, productionDate)

What I am trying to do is, fill out the second form with the prodDate value.
This is what the form looks like:

I am trying to populate the Year , Month , and Day fields using the prodDate argument it gets when the function is called.
This is the function that gets called:

public EditBOL(string BOL, string Batch, string prodDate)
    {
        InitializeComponent();
        txtBOL.Text = BOL;
        txtBatch.Text = Batch;
        //Code to breakdown prodDAte variable comes here!!
    }

I have tried a lot of different methods. I tried
1. DateTime.Parse(prodDate, "yyyy-mm-dd", culture)
2. DateTime.Now.ToString("yyyy-MM-dd h:mm tt");
3. DateTime dateVariable = prodDate??DateTime.MinValue
The reason I tried all this is, I don't want to use a substring on the dateProd variable in the function because, the date can either be 1-1-2015 or 10-10-2015 . The format is NOT mm-dd-yyyy 00:00:00.000 , it is md-yyyy 00:00:00.000
So, substring just seems stupid. So I am trying to convert the string to datetime variable and doing DatetimeVariable.Year , DatetimeVariable.Date , and DatetimeVariable.Month .

EDIT 1:Missed a few lines of code on how the date is selected from the table.

Try this if you insist to parse prodDate :

public EditBOL(string BOL, string Batch, string prodDate)
{
        InitializeComponent();
        txtBOL.Text = BOL;
        txtBatch.Text = Batch;
        //Code to breakdown prodDAte variable comes here!!
        string[] tokens = prodDate.Split(' ')[0].Split('-');
        yearTextBox.Text = tokens[0];
        monthTextBox.Text = tokens[1];
        dayTextBox.Text = tokens[2];
}

I would prefer this approach:

public EditBOL(string BOL, string Batch, string prodDate)
{
        InitializeComponent();
        txtBOL.Text = BOL;
        txtBatch.Text = Batch;
        //Code to breakdown prodDAte variable comes here!!
        DateTime date = Convert.ToDateTime(prodDate);
        yearTextBox.Text = date.Year.ToString();
        monthTextBox.Text = date.Month.ToString();
        dayTextBox.Text = date.Day.ToString();
}

You can just use DateTime.ParseExact() :

public EditBOL(string BOL, string Batch, string prodDate)
{
    InitializeComponent();
    txtBOL.Text = BOL;
    txtBatch.Text = Batch;

    string format = "yyyy-M-d h:m:s.fff";
    DateTime dt = DateTime.ParseExact(prodDate, format, CultureInfo.InvariantCulture);

    textBoxYear.Test = dt.Year.ToString();
    textBoxMonth.Test = dt.Month.ToString();
    textBoxDay.Test = dt.Day.ToString();
}
