vb.net - 如何将答案转换为两个小数点

Question

这是我的代码，我想要的输出是txtA.Text和txtB.Text保留两位小数。

Public Class Form1
    Private Sub btncalc_Click(ByVal sender As System.Object,
                              ByVal e As System.EventArgs) Handles btncalc.Click
      txtA.Text = Val(txtD.Text) / Val(txtC.Text) * Val(txtF.Text) / Val(txtE.Text)
      txtB.Text = Val(txtA.Text) * 1000 / Val(txtG.Text)
    End Sub
End Class

Answer 1

尝试使用Format函数:

Private Sub btncalc_Click(ByVal sender As System.Object,
                          ByVal e As System.EventArgs) Handles btncalc.Click
  txtA.Text = Format(Val(txtD.Text) / Val(txtC.Text) * 
                     Val(txtF.Text) / Val(txtE.Text), "0.00")
  txtB.Text = Format(Val(txtA.Text) * 1000 / Val(txtG.Text), "0.00")
End Sub
