ASP教程:ASP是不区分大小写 |

众所周知：asp(VBS)是不区分大小写的，但是你要理解这句话的意思，请看下面实例
Test.asp <% Dim aName If Request.QueryString("name") <> "" Then aName = Trim(Request.QueryString("name")) Select Case aName Case "new" Response.Write "New" Response.End Case "top" Response.Write "Top" Response.End Case Else Response.Write "Other" Response.End End Select Else Response.Write "No Value" Response.End End If %> 如果你执行http://localhost/test.asp?name=new，它会输出：New 而如果执行http://localhost/test.asp?name=New，它却输出：Other 所以确保不出现意想不到的错误，在select Case中先将条件转成大/小写，这样 <% Dim aName If Request.QueryString("name") <> "" Then aName = LCase(Request.QueryString("name")) Select Case aName Case "new" Response.Write "New" Response.End Case "top" Response.Write "Top" Response.End Case Else Response.Write "Other" Response.End End Select Else Response.Write "No Value" Response.End End If %> 总之，要理解VB不区分大小写的意思是什么... 对象名、属性名、变量名等本身构成的语法不区分大小写 然而属性值、变量值区分大小写，也就是说："A"="a"为false
