Question

我正在开发基于窗口的应用程序，我想从DateTimePicker Control禁用星期日。

可以禁用星期日吗？如果有这么好的帮助我。

Answer 1

试试这个。他们可能是一些更容易的解决方但我觉得这很容易：）

如果您选择的最后一个日期较小，并且如果您要下来，则会将您带到星期六。相当于禁用星期日

//你需要跟随三个变量来进行延伸

    DateTime lastDate;
    System.Text.RegularExpressions.Regex rg;
    bool valueChangingProgramatically = false;

    //If you have already Form_load Event, just add the body of following event in yours
    // Add form_load event and write this code in body
    private void Form1_Load(object sender, EventArgs e)
    {
        lastDate = dateTimePicker1.Value;
        rg = new System.Text.RegularExpressions.Regex("Sunday");
        if (lastDate < dateTimePicker1.Value)
            dateTimePicker1.Value = dateTimePicker1.Value.AddDays(1);
        // I am adding event of datetimepicker value changed at the end of FormLoad
        dateTimePicker1.ValueChanged += new EventHandler(dateTimePicker1_ValueChanged);
    }

    // valueChangingProgramatically avoids recursion/ infinte loop/repeteion of this event
    private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
    {
        if (!valueChangingProgramatically)
        {
            if (rg.IsMatch(dateTimePicker1.Value.ToLongDateString()))
            {
                valueChangingProgramatically = true;
                if (lastDate < dateTimePicker1.Value)
                    dateTimePicker1.Value = dateTimePicker1.Value.AddDays(1);
                else
                    dateTimePicker1.Value = dateTimePicker1.Value.AddDays(-1);
            }

        }
        else
            valueChangingProgramatically = false;
        lastDate = dateTimePicker1.Value;
    }
