文字列が有効なDateTimeエラーとして認識されませんでした

Question

はい、私はこの質問で多くのトピックを知っています、私は検索し、それらの多くを見たが、私はまだ私の問題を解決することはできません。

ERROR：文字列は、私は別の形であるのDataGridViewからのデータを受信して​​い

が、私はそれを受信し、それがうまく表示できる有効な日時として認識されませんでしたが、今、私はひそかにしたいです日付形式のString形式のデータをdatetimepickers形式で表示します。私は、この行のエラーを取得します

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; 
} 

：データを受信

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

"D 'デ・MMMM"ド' YYYY" 形式は、使用して1つのイムで、I DataPLevantamentoの

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

値がこのようなデータである：ちょうどフォーマットが何であるかを確認するために、この方法でフォーマットを得た

Answer 1

これはあなたに等しくなるように、実際のCultureInfo CultureInfoニーズに起因してカスタムカルチャ

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

Answer 2

を使用して、この方法を試してみてください、 ので、あなたは新しいCultureInfo変数を作成する必要があります。

私はこの言語がポルトガル語であると推測しました。

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);
