I have a user who is getting the above exception message when attempting to run the UpdateFields method on a aspose.words.document. This document is generated primarily through using the InsertHtml method on the docbuilder object and getting the source Html from user input. I’ve removed all the Html except for that which generates the error and have come up with the simple link, iron
(source code is iron)
Any idea why this would be generating that error?
Thanks.
Laurie
FYI: The full error message is:
**Error: Index and length must refer to a location within the string.
Parameter name: length: at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy)

Hi Laurie,
Thanks for your request. I cannot reproduce the problem on my side. I used the latest version of Aspose.Words for testing. You can download the latest version from here:
https://releases.aspose.com/words/net
I used the following code for testing:
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.InsertHtml("iron");
doc.UpdateFields();
doc.Save(@"Test001\out.doc");
Best regards,
Here’s my source code in a test file I used to recreate the error. It may have something to do with the fact that I’m using headers and generating a TOC.
aspx file:
<% @ Page Language = "C#"
AutoEventWireup = "true"
CodeFile = "TestPrintError.aspx.cs"
Inherits = "TestPrintError"
Title = "Test Print Error"
ValidateRequest = "false" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="radE" %>
AgPlan
<asp:ScriptManager ID="ScriptManager2" runat="server" />
Enter the text below, then click Print.
<asp: TextBox ID = "tbContent" runat = "server" Height = "300px" TextMode = "MultiLine" Width="400px">This is where the error happens: [iron](http://en.wikipedia.org/wiki/Iron "Iron")</asp:TextBox>
<asp:Button ID="btnPrint" runat="server" OnClick="btnPrint_Click" Text="Print" />
