  Opening web.config file in Multiline Textbox control

  Feb 04, 2012 07:14 PM|LINK

  hi,

  Actually, I'm a noob in working with files in asp.net and I need to implement a feature of " Editing web.config file at runtime." I know this sounds silly and I also know the consequences of this feature like it will restart the application but I really need to do this.

  Now, what I've thought for this is, showing all the content of web.config file in textbox and updating it with button placed just down the textbox.

  Can anyone help me in this.

  Thanks in Advance. [:)]

  Uisng LINQ-TO-XML can help you solve the problem easily——

  XDocument doc = XDocument.Load("xxx.xml");

  TextBox1.Text = doc.Root;

  //Updating：

  XDocument doc = XDocument.Parse(TextBox1.Text);

  doc.Save(Request.Mappath("~/")+"web.config");

  hi Decker Dong,

  Sorry for late reply because I got sick really bad one day before your reply.

  Decker Dong - MSFT

  XDocument doc = XDocument.Load("xxx.xml");

  I need to open web.config file and when I wrote:

   XDocument doc = XDocument.Load("~/web.config");

  It gave an error : "System.IO.FileNotFoundException: Could not find file 'C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\web.config'."

  and when I tried:

   XDocument doc = XDocument.Load(Server.Mappath("~/web.config"));

  It gave error: System.Web.HttpServerUtility' does not contain a definition for 'Mappath' and no extension method 'Mappath' accepting a first argument of type 'System.Web.HttpServerUtility' could be found (are you missing a using directive or an assembly reference?)

  can you suggest some solution.

  Thank you

  maybe MapPath，please do that according to the intellisense tip，I only give you an example，don't copy directly。

  And you should try to use Request.MapPath instead of Server.MapPath if still fails。

  thnx for replying Decker,

  I've managed to show web.config file on pageload event in textbox and on click button I'm updating the value.

   Now the problem is, the code for updating file executes successfully but file doesn't get updated.

  I've also written  <httpRuntime requestValidationMode="2.0" >

  Here's my code:

  .aspx file:

  <h1 class="h">Edit Web.Config File: </h1>
  <span style="border: solid red 1px; padding: 2px; margin: 3px; color: red; font-size: 12px;">
      <b>NOTE: </b>Be careful!  Web.config is easy to break!
      </span>
      <asp:TextBox ID="txtweb" runat="server" TextMode="MultiLine" Height="400px" Width="900px" Font-Underline="false"></asp:TextBox><br />
      <br />
      <asp:Button ID="btnupdate" runat="server" Text="Button"
          onclick="btnupdate_Click" />
          <br />

  .aspx.cs file:

      protected void Page_Load(object sender, EventArgs e)
      {
          load();
      }
  
      void load()
      {
          XDocument doc = XDocument.Load(Request.MapPath("~/web.config"));
  
          txtweb.Text = doc.Root.ToString();
      }
      protected void btnupdate_Click(object sender, EventArgs e)
      {
          //System.IO.StreamWriter sw = System.IO.File.CreateText(Request.MapPath("~/web.config"));
          //sw.Write(txtweb.Text);
          //sw.Close();
          //sw.Dispose();
          XDocument doc = XDocument.Parse(txtweb.Text);
          doc.Save(Request.MapPath("~/web.config"));
          load();
      }

  Thank you

  protected void Page_Load(object sender, EventArgs e) { load(); }

  1）Please add if (!IsPostBack){……} and put the codes inside——

  namespace WebAppCSharp
  {
  	public partial class Default : System.Web.UI.Page
  	{
  		private void MyLoad()
  		{
  			XDocument doc = XDocument.Load(Request.MapPath("~/web.config"));
  			TextBox1.Text = doc.Root.ToString();
  		}
  		protected void Page_Load(object sender, EventArgs e)
  		{
  			if (!IsPostBack)
  			{
  				MyLoad();
  			}
  		}
  
  		protected void Button1_Click(object sender, EventArgs e)
  		{
  			XDocument doc = XDocument.Parse(TextBox1.Text);
  			doc.Save(Request.MapPath("web.config"));
  			MyLoad();
  		}
  	}
  }

  2）Notice that you web.config should be dealt with this：

  <?xml version="1.0" encoding="utf-8"?>
  <configuration>
    <system.web>
      <compilation debug="true" targetFramework="4.0" />
      <httpRuntime requestValidationMode="2.0" />
    </system.web>
  </configuration>
