Question

我想将总分钟转换为天数小时和分钟。我是vb的新手，还在努力学习...... 这是我的代码......

    Private Sub TextBox3_TextChanged(sender As Object, e As EventArgs) Handles TextBox3.TextChanged
    TextBox1.Text = TextBox3.Text / 1440
    End Sub


    Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
    TextBox3.Text = TextBox1.Text * 1440
    TextBox7.Text = TextBox1.Text / 24
    End Sub

    Private Sub TextBox7_TextChanged(sender As Object, e As EventArgs) Handles TextBox7.TextChanged
    TextBox1.Text = TextBox7.Text * 24
    End Sub

当我运行它时，我有十进制的答案..任何人都可以建议我这样做的正确方法吗？我不想要小数。

Answer 1

看起来你不理解变量的概念，你不需要有三个不同的处理程序来完成这项工作，你可以在一个处理程序中完成所有操作。

你可以在算术上做你想做的事，但在我看来，更简单的方法是使用TimeSpan。它看起来像这样：

'TextBox1 is where the user inputs the number of minutes
Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
    Dim d = TimeSpan.FromMinutes(TextBox1.Text) 'creates a TimeSpan based on user input, this is also a variable creation


    TextBox5.Text = d.ToString("dd\:hh\:mm") 'you can format it with a custom format


    'Or you can access the elements of the TimeSpan like so

    TextBox2.Text = d.Days
    TextBox3.Text = d.Hours
    TextBox4.Text = d.Minutes
End Sub
