Question

我想在结果中只显示2个十进制数字，但我不知道如何。这是我的代码：

Public Class Form1
    Dim data1 As Double
    Dim data2 As Double

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        data1 = TextBox1.Text
        data2 = TextBox2.Text
        Label4.Text = (data1 / data2) * 100 & "Liter / 100 Km"
    End Sub

    Private Sub TextBox1_KeyPress(sender As Object, e As KeyPressEventArgs) Handles TextBox1.KeyPress
        If Asc(e.KeyChar) < 48 Or Asc(e.KeyChar) > 57 Then
            e.Handled = True
            MsgBox("Csak szám", MsgBoxStyle.Critical, "Hiba")
        End If
    End Sub

    Private Sub TextBox2_KeyPress(sender As Object, e As KeyPressEventArgs) Handles TextBox2.KeyPress
        If Asc(e.KeyChar) < 48 Or Asc(e.KeyChar) > 57 Then
            e.Handled = True
            MsgBox("Csak szám", MsgBoxStyle.Critical, "Hiba")
        End If
    End Sub
End Class

Answer 1

data1.ToString（ “C”）; //将根据文化显示$ 1000.00，$ 1000,00等 // 要不就 data1.ToString（ “N2”）; 1000m.ToString（ “F2”）; //对于普通数字：1000.00,1000,00

结果只显示2位小数
