需要转换并将文本框值格式化为十进制数据

本文介绍了需要转换并将文本框值格式化为十进制数据的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我一直在阅读帮助我需要如何使用十进制货币货币确实 不存在，就像我在vb6中使用的那样。 我在google上遇到了困难msdn发现如何或者我是否可以将文本框的 值作为十进制或者我只需要再制作一个小数 变量 。所以我猜了一下，如果我在没有 波浪线的情况下打字，CDec就会变成蓝色。但这实际上是将其转换为十进制。 接下来如果是这样，我不喜欢输出文本框 总计：100 税：4.500我需要格式化为4.50 毛：95.5 分割：48这不准确，它是四舍五入的，当然应该是 95.5的一半，47.75 < code> Private Sub Button1_Click（ByVal sender As System.Object，_ ByVal e As System.EventArgs）处理btnCalc.Click ''按钮1计算 Const税为十进制= 0.045 Dim a As Integer for a = 1 to 5 lblTotal.Text = CDec（Val（lblTotal.Text））+ CDec（Val（txtCoinsInArray（a）.Text）） 下一页 如果chkUncleSam.Checked = True那么 lblTax.Text = CDec（ Val（lblTotal.Text））*税 结束如果 lblGross.Text = CDec（Val（lblTotal.Text）） - CDec（Val（lblTax.Text）） lblSplit.Text = CDec（Val（lblGross.Text））\ 2 结束次级 结束班级 < / code> - Adam S

I have been reading in help how I need to use decimal becuase currency does not exist like I used in vb6. I had a difficult time on google and msdn finding how or if I can take the value of text box as decimal or do I just have to make another decimal variable .. So I took a guess hoping CDec would come up blue if I type it in with no squigglies on the line. But is this actually converting it to decimal. Next if so, I do not like the out put to the textboxes Total: 100 Tax: 4.500 I need it formatted as 4.50 Gross: 95.5 Split: 48 This is not accurate, it is rounding, It should be of course half of 95.5, 47.75 <code> Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnCalc.Click ''Button 1 Calculate Const Tax As Decimal = 0.045 Dim a As Integer For a = 1 To 5 lblTotal.Text = CDec(Val(lblTotal.Text)) + CDec(Val(txtCoinsInArray(a).Text)) Next If chkUncleSam.Checked = True Then lblTax.Text = CDec(Val(lblTotal.Text)) * Tax End If lblGross.Text = CDec(Val(lblTotal.Text)) - CDec(Val(lblTax.Text)) lblSplit.Text = CDec(Val(lblGross.Text)) \ 2 End Sub End Class </code> -- Adam S

不存在像我一样在vb6中使用。我在google和msdn上遇到困难时间如何或者如果我可以将 not exist like I used in vb6. I had a difficult time on google and msdn finding how or if I can take 文本框的值作为十进制或者我是否可以

只需要制作另一个小数变量。所以我猜了一下，如果我输入没有波浪线，CDec就会变成蓝色。但这实际上是将其转换为十进制。 接下来如果是这样，我不喜欢输出到文本框总计：100 税：4.500我需要格式化为4.50 总额：95.5 分裂：48这不准确，它是四舍五入的，当然应该是95.5的一半，47.75 < code> Private Sub Button1_Click（ByVal sender As System.Object，_ ByVal e As System.EventArgs）处理btnCalc.Click ''按钮1计算 Const Tax As Decimal = 0.045 以整数为单位对于a = 1到5 lblTotal.Text = CDec（Val（lblTotal.Text））+ CDec（Val（txtCoinsInArray（a）.Text ））下一页如果chkUncleSam.Checked = True那么 lblTax.Text = CDec（Val（lblTotal.Text））*税结束如果 lblGross.Text = CDec（Val（lblTotal.Text）） - CDec（Val（lblTax.Text）） lblSplit.Text = CDec（Val（lblGross.Text））\ 2 End Sub End Class < / code> - Adam S
