我尝试过：



i尝试了这个，但它给了我输出错误

i think its simple but i find it confusing.

What I have tried:

i tried this but it gives me an output error

Dim date1 As Date = #7:00:00 AM#
        Dim date2 As Date = #10:00:00 AM#
        Dim date3 As Date = #1:00:00 PM#
        Dim date4 As Date = #4:00:00 PM#

            TextBox6.Text = "here"
        ElseIf TimeOfDay = date4 Then
            TextBox2.Text = "here"
            TextBox7.Text = "here"
        ElseIf TimeOfDay = date3 Then
            TextBox3.Text = "here"
            TextBox8.Text = "here"
        ElseIf TimeOfDay = date2 Then
            TextBox4.Text = "here"
            TextBox9.Text = "here"
        ElseIf TimeOfDay = date1 Then
            TextBox5.Text = "here"
            TextBox10.Text = "here"
        End If

推荐答案

根据您的描述，下面是代码的外观，尽管我不确定您的意图。无论如何，你应该只包括小时和安培来进行比较。

Based on what you described, below is how the code should look like although I'm not sure what you intend is. Anyway, you should only include hours and ampm for comparison.

Dim date1 As Date = #7 AM#
        Dim date2 As Date = #10 AM#
        Dim date3 As Date = #3 PM#
        Dim date4 As Date = #4 PM#
        Dim date5 As Date = #2 PM#

        Dim TimeOfDay = DateTime.Now.ToString("HH tt")

        If TimeOfDay = date5 Then
            TextBox1.Text = "here"
            TextBox6.Text = "here"
        ElseIf TimeOfDay = date4 Then
            TextBox2.Text = "here"
            TextBox7.Text = "here"
        ElseIf TimeOfDay = date3 Then
            TextBox3.Text = "here"
            TextBox8.Text = "here"
        ElseIf TimeOfDay = date2 Then
            TextBox4.Text = "here"
            TextBox9.Text = "here"
        ElseIf TimeOfDay = date1 Then
            TextBox5.Text = "here"
            TextBox10.Text = "here"
        End If

您的问题不是特别清楚。如果您只想在单个文本框中显示当前时间，请使用：

Your question is not particularly clear. If you just want to show the current time in a single textbox, use:

textbox.Text = String.Format("It's {0:h tt}", DateTime.Now)

自定义日期和时间格式字符串 [ ^ ]



如果你想要别的东西，那么你需要解释你的要求。

Custom Date and Time Format Strings[^]

If you want something else, then you're going to need to explain your requirements.
