问一个split的有关问题

问一个split的问题
我现在从txt文件中读取了数据
 Dim a1() As string
  Dim a As String
  Dim sr As IO.StreamReader '
  Dim i As Integer
  sr = New IO.StreamReader("d:\111.txt", System.Text.Encoding.GetEncoding("GB2312"))
  a = sr.ReadToEnd
现在我想用split来分割，遇到空格和回车都分割，不知道怎么弄，只会单独分割空格和回车。
  a1 = Split(a, " ")
  a1 = Split(a, chr（10）)

怎么同时分割呢？

[解决办法]

VB.NET code

a1 = a.Split(new String {vbCrLf," "},StringSplitOptions.RemoveEmptyEntries)
[解决办法]
   Try
           Dim b As String() = Split(a, vbCrLf)
           Dim c As String()
           Dim x, y As String
        
           For Each x In b
               Dim i As Integer = 0
               c = Split(x.ToString, " ")
               For Each y In c
                   MsgBox(y)
               Next
               i = i + 1
           Next

       Catch ex As Exception
           MsgBox(ex.Message)
       End Try

y 就是你想要的 同时分割 后的字符串！
