每次点击都会添加一天 [英] Adding one day with each click

问题描述

我里面有一个TextBox日期dd / MM / yyyy格式

点击时我有一个按钮我想在文本框中找到一天添加一天。



示例TextBox：15/09/2013当我点击我希望文本框文本为16/09/2013



I使用下面的代码，但它在服务器上发布时开始添加月份：

I have a TextBox inside it a date dd/MM/yyyy format
I have a button when clicked I want to add one day to the date found in the textbox.

Example TextBox: 15/09/2013 When I click I want the textbox text be 16/09/2013

I used this code below but it started adding month when published on server:

date_add.Text = CDate(date_add.Text).AddDays(1).ToString("dd/MM/yyyy")

推荐答案

Private Sub MyButton_Click(sender As Object, e As EventArgs) Handles MyButton.Click
   Dim culture As New CultureInfo("fr-FR", false) '' Here I took french culture because I'm sure it represents the DateTime format the way you want, i.e. dd/MM/yyyy
   Dim myDate As DateTime
   myDate = DateTime.Parse(date_add.Text, culture)
   date_add.Text = myDate.AddDays(1).ToString("dd/MM/yyyy")
End Sub

希望这有帮助

您可以使用它来减去日期，并将现有数据添加到您的文本框中。一旦你使用这些方法你就可以得到这些值，你可以打印它们，或者你可以设置一个带有新值的文本框。

You can use this to subtract and add days to the existing data may be in your in a text box. Once you use these methods you get the values and u can print them or you can set teh text box with a fresh value.

using System;

class Program
{
    static void Main()
    {
    Console.WriteLine("Today: {0}", DateTime.Today);

    DateTime y = GetYesterday();
    DateTime z = GetTomorrow();
    Console.WriteLine(y,z);
    }

    /// <summary>
    /// Gets the previous day to the current day.
    /// </summary>
    static DateTime GetTomorrow()
    {
    // Add 1 to now
    return DateTime.Today.AddDays(1);
    }

    static DateTime GetYesterday()
    {
    // Add -1 to now
    return DateTime.Today.AddDays(-1);
    }

}
