C#-将所选日期从monthCalendar保存到字典中
我正在用C#做日历。为此,我使用MonthCalendar(windows窗体)。 我想在日历上选择一个日期,并为该日期添加一些文本(如约会)。然后我想把日期和文本保存在字典里C#-将所选日期从monthCalendar保存到字典中,c#,dictionary,monthcalendar,C#,Dictionary,Monthcalendar,我正在用C#做日历。为此,我使用MonthCalendar(windows窗体)。 我想在日历上选择一个日期,并为该日期添加一些文本(如约会)。然后我想把日期和文本保存在字典里 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq;

Dictionary<DateTime, string> dictionary = new Dictionary<DateTime, string>();
dictionary.Add(geselecteerdeDatum, textBox1.Text);
//show what is in the dictionary / print it in the console
Console.WriteLine(geselecteerdeDatum);
foreach (KeyValuePair<DateTime, string> kvp in dictionary)
{
Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);

public DateTime geselecteerdeDatum{ get; set; }

有人知道如何在字典中获取所选日期吗?更改
字典.Add(geselecteerdeDatum,textBox1.Text)代码>
添加(monthCalendar1.SelectionStart,textBox1.Text)代码>
而且无需多次设置MaxSelectionCount
(您可以在表单设计器中进行设置)
var geselecteerdeatum
创建一个新的字符串变量(本地),该变量与您的DateTime geselecteerdeatum
您在DateSelected事件中有var geselecteerdeatum
。这超出了范围。删除var并确保在表单范围内声明变量。您的意思是:确保在表单范围内声明变量?在编辑之前,我没有在任何地方看到您的geselecteerdeDatum变量。很抱歉,我粘贴代码并将其翻译为英语时出错。
Key = 1-1-0001 00:00:00, Value = message
