从字符串“ FalseTrue”到类型“ Boolean”的转换无效-Exception

Question

这是我的VB Net代码：

Public Class Form1

   Dim hue As Single

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles      Button1.Click
   Dim hueMin As Single = 205
     Dim hueMax As Single = 259

            If (hue > hueMin) & (hue < hueMax) Then

                 bmp.SetPixel(Xcor, Ycor, Color.Black)

             End If
   End Sub

End Class

我进入这一行：

            If (hue > hueMin) & (hue < hueMax) Then

此异常：

{“从字符串“ FalseTrue”到类型“ Boolean”的转换无效。”}

任何想法我怎么解决代码？先感谢您。

正确的测试应该是

If (hue > hueMin) AndAlso (hue < hueMax) Then 
                   ^^^^

将&在VB.Net是串连接操作。
