如何在C#中移除Word文档页眉页脚并修改字体后保存？

Great work on getting the font modification up and running! Let's expand your code to include removing headers and footers, plus add proper cleanup to avoid leaving Word processes lingering in the background.

Here's the complete modified code:

using Word = Microsoft.Office.Interop.Word;
using System.Runtime.InteropServices; // For clean COM object release

class WordDocumentTool
{
    static void Main()
    {
        Word.Application wordApp = null;
        Word.Document targetDoc = null;

        try
        {
            wordApp = new Word.Application();
            // Replace with your actual document path
            targetDoc = wordApp.Documents.Open(@"C:\Your\File\Path\Document.docx");

            // Modify font for the entire document
            Word.Range fullDocumentRange = targetDoc.Content;
            fullDocumentRange.Font.Name = "Times New Roman";

            // Remove headers and footers from all document sections
            foreach (Word.Section section in targetDoc.Sections)
            {
                // Clear all headers in the section
                foreach (Word.HeaderFooter header in section.Headers)
                {
                    if (header.Exists)
                    {
                        // Unlink from previous sections to ensure we modify this header
                        header.LinkToPrevious = false;
                        // Delete the header content
                        header.Range.Delete();
                    }
                }

                // Clear all footers in the section
                foreach (Word.HeaderFooter footer in section.Footers)
                {
                    if (footer.Exists)
                    {
                        footer.LinkToPrevious = false;
                        footer.Range.Delete();
                    }
                }
            }

            // Save the updated document
            targetDoc.Save();
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Oops, something went wrong: {ex.Message}");
        }
        finally
        {
            // Clean up to prevent orphaned Word processes
            if (targetDoc != null)
            {
                targetDoc.Close();
                Marshal.ReleaseComObject(targetDoc);
            }
            if (wordApp != null)
            {
                wordApp.Quit();
                Marshal.ReleaseComObject(wordApp);
            }
        }
    }
}

Key Additions Explained: #

• Header/Footer Removal: We loop through every section in the document (since Word files can have multiple sections with unique headers/footers). For each header/footer, we first unlink it from previous sections (so changes apply to this section specifically), then delete its content.
• Cleaner Font Modification: Replaced the start/end object approach with targetDoc.Content—it does the same job of targeting the entire document but is more concise.
• Proper Cleanup: Wrapped the code in a try-finally block to ensure we always close the document and quit the Word app, even if an error occurs. Using Marshal.ReleaseComObject helps avoid hidden Word processes running in the background, which is a common pitfall with interop code.

Quick Notes: #

• Swap out the file path in Documents.Open() with your actual document location.
• If your document only has one section, you could skip the loop and target targetDoc.Sections[1] directly, but looping ensures no headers/footers are missed across all sections.
• Make sure you have the Microsoft.Office.Interop.Word NuGet package installed in your project.
