vbc生成dll时，语句中有instr,split，编译错误，请问如何解决！

Question

在用vbc.exe来生成dll文件时总是报错（vb.net）
 error BC30451: 名称“Split”未声明。  SplitSQL = Split(strSQL)
             ~~~~~
 error BC30451: 名称“InStr”未声明，名称“UCase”未声明。    If InStr("INSERT,DELETE,UPDATE",  UCase$(SplitSQL(0))) Then
       ~~~~~                          ~~~~~
。
。
各位大虾，请帮忙！

Answer 1

楼上的请说的详细点吧
应该加什么名称空间
 system.dll,system.data.dll,system.xml,都加了应该没有问题了
但就是这些原来的VB中的函数不认了，请指点~~~~

Answer 2

引入 Microsoft.VisualBasic 命名空间split 的用法应该是 String.Split()Instr 在Microsoft.VisualBasic 命名空间
