请教个问题：

产品表中有一列“规格型号”，想在此列中显示带分数（如：1 1/4），显示方式是要：分子在上面，分母在下面那种。如何做？

8楼的方法,能不能用分子在上面，分母在下面显示？

Dim d As Double = -11.75           \'要转化的小数
Dim d1str As String                    \'最后结果的整数部分
Dim d2str As String                    \'最后结果的分数部分

Dim d1 As Integer = Math.Truncate(d)        \'d的整数部分,包括符号
If d1 <> 0 Then d1Str = d1                       \'如果整数部分不为0,则保存下来

If d.ToString.IndexOf(".") > -1 Then           \'如果有小数部分不为0
    Dim d2 = d.ToString.Split(".")(1)            \'取得小数部分
    Dim n As Integer = d2.ToString.Length  \'小数位数
    Dim num As Integer = d2                      \'分子,未约分
    Dim den As Integer = 10^n                   \'分母,未约分
    Dim x As Integer = num
    Dim y As Integer = den
    Dim temp As Integer
    Do While x <> 0                   \'Do Loop 求最大公约数
        temp = y Mod x
        y = x
        x = temp
    Loop                              \'循环结束,最大公约数保存在变量y中
    d2str = d1str * (den/y) + iif(d1str>0, num/y, -num/y) & "/" & den/y       \'约分
End If
Return d2str

上面代码，显示 -47/4

d2str = num/y & "/" & den/y       \'约分

能不能把结果显示成竖状的，就是分子在上面，分母在下面那种。

如果用“ListView”，把一些常用的分数做成图片，是否可行？

你可以用画图的方式画分数，如

Dim zs As String = "11"
Dim fz As String = "3"
Dim fm As String = "4"

Dim fnt As New Font("宋体",20)
Dim gc = basemainform.CreateGraphics
Dim size = gc.MeasureString(zs & fm, fnt)

Dim bmp As new Bitmap(cint(size.width)+10, cint(size.height) * 2+10)
Dim g = Graphics.FromImage(bmp)

g.DrawString(zs,fnt,Brushes.black,0, 0.5*size.height)
Dim zssize = gc.MeasureString(zs, fnt)
g.DrawString(fz,fnt,Brushes.black,zssize.width, 0)
g.DrawString(fm,fnt,Brushes.black,zssize.width, size.height+5)
Dim fmsize = gc.MeasureString(fm, fnt)
g.DrawLine(Pens.Black,zssize.width,size.height+2,zssize.width+fmsize.width+3,size.height+2)

bmp.save("d:\\test2.jpg")
