c# - SQL Server 中的日期时间问题

Question

我正在尝试将 INSERT 插入到 MS SQL Server 中已设置的数据库中，数据库服务器位于共享主机 (godaddy) 中。

我想要实现的是将一篇文章存储到数据库中，但每次我发布或预览该文章时，服务器都会向我抛出

SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.

我在共享主机中有一个 Datetime 类型的字段，它应该包含文章的日期，顺便说一句，它不会在其他文章表上抛出这个错误。就这一个，可能是打字错误还是什么？

这是我的代码(抛出错误的代码):

public partial class CrearServicio : System.Web.UI.Page
{
    string tpCont = "1";
    int estatus = 1;
    bool withResponse = true;

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            TextBox1.Attributes.Add("onKeyDown", "textCounter(this, 'counter1', 500)");
            TextBox1.Attributes.Add("onKeyUp", "textCounter(this, 'counter1', 500)");

            datetime.Text = DateTime.Now.ToString("yyyyMMddHHmmss");

            if (Request.QueryString["tpCont"] != null)
            {
                tpCont = Request.QueryString["tpCont"];
                volver.HRef = "elegir.aspx?tpCont=" + tpCont;
                volver1.HRef = "elegir.aspx?tpCont=" + tpCont;
            }

            ConexionServiciosDataContext db = new ConexionServiciosDataContext();

            tpContinpt.Text = tpCont;

            int role = kernel.getUserRole(User.Identity.Name);

            int tipoUsuario = role;

            if (tipoUsuario == 1 || tipoUsuario == 2)
            {
                mainButton.Visible = true;
                saveButton.Visible = true;
                displayButton.Visible = true;
            }
        }
    }

    protected void SaveDBAndDisplay(object sender, EventArgs e)
    {
        withResponse = false;

        SaveDB(sender, e);
    }

    protected void SaveDB(object sender, EventArgs e)
    {
        estatus = 2;

        InsertDB(sender, e);
    }

    protected void InsertDB(object sender, EventArgs e)
    {
        tpCont = tpContinpt.Text;

        if (TextArea1.Text.Length > 0)
        {
            ConexionServiciosDataContext db = new ConexionServiciosDataContext();

            Servicios columna = new Servicios();
            columna.Título = TextBox1.Text.ToString();
            string line = TransformarString(TextArea1.Text.ToString());
            columna.Contenido = line.ToString();

            string[] IDsTitlesLocations = { };

            db.Servicios.InsertOnSubmit(columna);
            db.SubmitChanges();
        }
}
}

对不起，如果我写得太多，但我只是停留在这个问题上，也许我应该在服务器上设置日期时间格式？

任何人都可以阐明这一点吗？

Answer 1

我假设 Servicios有DateTime未设置的属性。

DateTime s 不可为空，当它们未设置时，它们默认为 {1/1/0001 12:00:00 AM} .

调用db.SubmitChanges() ，您正试图将一个值插入到 DateTime 中列是 SQL SERVER 支持的较低值，如您的异常所示。

SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.
