I was trying to insert data into a field of type Datetime, but the control that I used was a textBox, I converted the datetime value, but when trying to insert the following message appears: "Input string was not in the correct format. ". I wanted to help me, the code snippet is as follows:

推荐答案

 

    DateTime dtHoraInicio;
    DateTime dtHoraFim;

    if (!DateTime.TryParse(horaInicio.Text, out dtHoraInicio)) {
        MessageBox.Show("'" + horaInicio.Text + "' could not be converted to a date.");
        return;
    }

    if (!DateTime.TryParse(horaFim.Text, out dtHoraFim)) {
        MessageBox.Show("'" + horaFim.Text + "' could not be converted to a date.");
        return;
    }
