Error copying font

Aspose.Words Product Family

Hello,


I’m using an IReplacingCallback to replace some text in a document. As part of this I’m cloning the Font of a Node. Occasionally an exception is thrown when cloning the font’s StyleIdentifier:

current.Font.StyleIdentifier = copy.StyleIdentifier;

The exception is:

System.ArgumentException: Cannot return user defined styles by style identifier.
at Aspose.Words.StyleCollection.xf21e14e2c9db279a(StyleIdentifier xa3be2ccad541ab25, Boolean x988fcf605f8efa7e)
at Aspose.Words.StyleCollection.x590d8ef356786501(StyleIdentifier xa3be2ccad541ab25)
at Aspose.Words.Font.set_StyleIdentifier(StyleIdentifier value)

Why is this exception thrown and how should I avoid it? Thanks

Hi

Thank you for additional information. You should modify your code as shown below (see my comments in the code):

// You cannot set StyleIdentifier.User this identified does nto correspond to any specific style.

// This identified means that style is not standard and created by user, this can be any style created by user.

if (copy.StyleIdentifier != StyleIdentifier.User)

current.Font.StyleIdentifier = copy.StyleIdentifier;

// You have to check whether the style exists in the document, if not, you cannot use it.

if (current.Document.Styles[copy.StyleName] != null)

current.Font.StyleName = copy.StyleName;

Best regards,
