FileUpload 好像有问题啊。。。。。。。。。。。
Dim   line   as   string   =   " "
while(true)
        line   +   =     New   StreamReader（FileUpload   .FileContent）.ReadLine
        If   (IsNothing(Line))   Then
                Exit   While
          End   If
End   While


‘然后我获得了一个line字符串啊。因为我需要用这个字符串啊。


‘接着我存储这个文件的时候。这个文件总是空啊是不是FileUpload   有问题啊？
Dim   path   as   String= "xxxxxxxx "
FileUpload.SaveAs(path)

这个文件总是空啊是不是FileUpload 有问题啊 ========> 可跟踪一下,看有没有上传文件.用streamreader读取不会影响这个文件.
------解决方案--------------------
FileUpload 没有任何问题。你的使用方法有问题、

------解决方案--------------------
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim line As String = " "
Dim sum As String = " "
Dim sr As New StreamReader(FileUpload1.FileContent)
While (True)

line = sr.ReadLine
If (IsNothing(line)) Then
Exit While
sr.Dispose()
Else
sum += line
End If
End While


Dim bFlag As Boolean = sum.IndexOf( "xxxxxx ") < 0
If (Not bFlag) Then
FileUpload1.SaveAs(Server.MapPath( "~/upload/ ") & System.IO.Path.GetFileName(FileUpload1.FileName))
Else
Response.Write( "没有找到 ")
End If

End Sub

逻辑不对~
