</html>我试图找出我如何可以使用currentDate变量来设置的抵达日期（如2017年10月10日 - 2017年10月10日）在控制的盒子每次页面加载。这是我自己试过的代码，但每次我测试页面时，都没有任何东西会自动放入该控件的文本框中。有人能帮我吗？除此以外的任何其他来源（https://www.quora.com/How-do-I-populate-date-automatically-in-a-text-box-in-asp-net）？
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace XEx06Reservation
{
public partial class Request : System.Web.UI.Page
{
private string currentDate = DateTime.Today.ToString("d");
private string currentYear = DateTime.Today.Year.ToString();
protected void Page_Load(object sender, EventArgs e)
{
txtArrivalDate.Text = currentDate;
}
}
}
答
我认为这是你在找什么： -
在.aspx页面： -
<asp:Label ID="lblYear" runat="server"></asp:Label>
<asp:TextBox ID="txtArrivalDate" runat="server"></asp:TextBox>
在你.aspx.cs页： -
public partial class WebForm1 : System.Web.UI.Page
{
private static readonly DateTime currentDate = new DateTime(2017, 10, 10);
private string currentYear = DateTime.Today.Year.ToString();
protected void Page_Load(object sender, EventArgs e)
{
txtArrivalDate.Text = currentDate.ToString();
lblYear.Text = currentYear;
}
}
@Federico Dipuma你能帮我吗？ – dorakta
关于代码应该显示'9/23/2017' * *取决于Windows *的语言首选项。什么不起作用，你的预期结果是什么？ – Win
@Win我想在每次页面加载时在我的网页上的文本到达日期控件中自动设置预定义日期10/10/2017。但它只是输出mm/dd/yyyy。你可以帮我吗？ – dorakta
