Char的问题
Dim V_char As Char
If V_char.ToString() = String.Empty Then
Response.Write( "A ")
Else
Response.Write( "B ")
End If

'为什麽会输出B， 如何修改If条件才能输出A

[解决办法]
V_char的赋值是什么？

V_char.ToString()当然不等于String.Empty
[解决办法]
Dim V_char As Char
If V_char = Nothing Then
Response.Write( "A ")
Else
Response.Write( "B ")
End If
