ERROR: The string was not recognized as a valid DateTime

I am receiving data from a datagridview that is in a different form, i receive it and can display it just fine, but now i want to covert the data that are in String format to date format and display it on datetimepickers forms.

Receiving data:

    public EditObras(string id, string NomeObra, string idCliente, string DataPLevantamento, string DataRLevantamento, string Estado, string DataRMateriais, string DataInicioObra, string DataConclusao, string DataVestoria, string Obs, string Prompor, string Levantpor, string executpor)
        {
            InitializeComponent();
            label4.Text = (string)id;
            textBox1.Text = (string)NomeObra;
            textBox2.Text = (string)idCliente;
            dateTimePicker1.Value = DateTime.ParseExact(DataPLevantamento, "d' de 'MMMM' de 'yyyy", System.Globalization.CultureInfo.CurrentCulture, System.Globalization.DateTimeStyles.None);
            // textBox3.Text = (string)DataPLevantamento;
            textBox4.Text = (string)DataRLevantamento;
            comboBox1.Text = (string)Estado;
            textBox5.Text = (string)DataRMateriais;
            textBox6.Text = (string)DataInicioObra;
            textBox7.Text = (string)DataConclusao;
            textBox8.Text = (string)DataVestoria;
            textBox12.Text = (string)Obs;
            textBox9.Text = (string)Prompor;
            textBox10.Text = (string)Levantpor;
            textBox11.Text = (string)executpor;
}

I get the error on this line:

dateTimePicker1.Value = DateTime.ParseExact(DataPLevantamento, "d' de 'MMMM' de 'yyyy", System.Globalization.CultureInfo.CurrentCulture, System.Globalization.DateTimeStyles.None);

The "d' de 'MMMM' de 'yyyy" format, is the one im using, i got the format with this way, just to see what the format is:

string datePattern = System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat.LongDatePattern;
        textBox1.Text = datePattern;

Value of DataPLevantamento is a data like this:

30 de outubro de 2016

Answer 1

This is due to the actual CultureInfo The CultureInfo needs to be equal to yours, so you must create a new CultureInfo variable.

I guessed that this language were Portuguese.

string DataPLevantamento = "30 de outubro de 2016";
    var provider = new System.Globalization.CultureInfo("pt-PT"); 
    string result = DateTime.ParseExact(DataPLevantamento,
                        "d' de 'MMMM' de 'yyyy",
                        provider,
                        System.Globalization.DateTimeStyles.None).ToString();
    Console.WriteLine(result);

Answer 2

Try this way using custom culture

CultureInfo culture = new CultureInfo("pt-PT"); 
dateTimePicker1.Value = DateTime.ParseExact(DataPLevantamento, "d' de 'MMMM' de 'yyyy", 
                        culture, System.Globalization.DateTimeStyles.None);
