如何用asp.net創建一個新文件？

我想創建一個文件與ASP提示用戶給一個文件名，然後它將運行Sub CreateFile_Click這將創建新的文件。新文件應該與提示中輸入的用戶名稱相同。如何用asp.net創建一個新文件？

由於某種原因，即時得到

+System.IO.File.Create(filepath).Dispose() 
    {"Access to the path 'C:\futu.txt' is denied."} 
    System.UnauthorizedAccessException 

<script language="VB" runat="server"> 
Sub CreateFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) 

    Dim strFileName As String = funcParam.Value 
    Dim filepath as String = "C:\futu.txt" 
If Not System.IO.File.Exists(filepath) Then 
    System.IO.File.Create(filepath).Dispose() 
End If 

'custom code to create a text file 
End Sub 
</script> 
<html> 
<head> 
<script language="JavaScript"> 
    //ask for user input and then create file 
    function CreateFile() { 
     //get filename from the user 
     var fileName = prompt('Type the name of the file you want to create:', ''); 
     //if the user clicks on OK and if they have entered something 
     if ((fileName) && (fileName != "")) { 
      //save the filename to the hidden form field 'funcParam' 
      document.forms['myForm'].elements['funcParam'].value = fileName; 
      //call the postback function with the right ID 
      __doPostBack('CreateFile', ''); 
     } 
    } 
</script> 
</head> 

<body> 
<form runat="server" id="myForm"> 
<a href="javascript:CreateFile();">Create Text file</a> 
<asp:linkbutton id="CreateFile" runat="server" onclick="CreateFile_Click" /> 
<input type="hidden" runat="server" id="funcParam"> 
</form> 
</body> 
</html>
