Word Automation: Replace an Image using C#

问题

I'm trying to change text and images in a word document using c# and word automation. I've got it working fine for text where I do something like the snippet below, but I don't even know how to start for replacing the image.

Any help is greatly appreciated!

Oliver

using Microsoft.Office.Interop.Word;
...

private static Application WordApp;
private static object missing = System.Reflection.Missing.Value;
private static object yes = true;
private static object no = false;

...
object search;
object replace;

object replaceAll =
    Microsoft.Office.Interop.Word.WdReplace.wdReplaceAll;

object filename = SourceFile;
object destination = DestinationFile;

Document d = WordApp.Documents.Open(
    ref filename, ref missing, ref missing, ref missing, ref missing,
    ref missing, ref missing, ref missing, ref missing, ref missing,
    ref missing, ref missing, ref missing, ref missing, ref missing,
    ref missing);

d.Activate();
search = "OLDSTRING";
replace = "NEWSTRING";
WordApp.Selection.Find.Execute(
    ref search, ref yes, ref yes, ref no, ref no, ref no, ref yes,
    ref missing, ref missing, ref replace, ref replaceAll,
    ref missing, ref yes, ref missing, ref missing);

You can loop through the InlineShapes and replace the pictures

using System.Collections.Generic;
using Word = Microsoft.Office.Interop.Word;

namespace WordExample
{
    class WordExample
    {
        #region Constructor
        public WordExample()
        {
            WordApp = new Microsoft.Office.Interop.Word.Application();
        }
        #endregion

        #region Fields
        private Word.Application WordApp;
        private object missing = System.Reflection.Missing.Value;
        private object yes = true;
        private object no = false;
        private Word.Document d;
        private object filename = @"C:\FullPathToFile\example.doc";
        #endregion

        #region Methods
        public void UpdateDoc()
        {
            d = WordApp.Documents.Open(ref filename, ref missing, ref no, ref missing,
               ref missing, ref missing, ref  missing, ref  missing, ref  missing,
               ref  missing, ref missing, ref yes, ref  missing, ref  missing, ref  missing, ref  missing);
            List<Word.Range> ranges = new List<Microsoft.Office.Interop.Word.Range>();
            foreach (Word.InlineShape s in d.InlineShapes)
            {
                if (s.Type == Microsoft.Office.Interop.Word.WdInlineShapeType.wdInlineShapePicture)
                {
                    ranges.Add(s.Range);
                    s.Delete();
                }
            }
            foreach (Word.Range r in ranges)
            {
                r.InlineShapes.AddPicture(@"c:\PathToNewImage\Image.jpg", ref missing, ref missing, ref missing);
            }
            WordApp.Quit(ref yes, ref missing, ref missing);
        }
        #endregion
 }
}

Do you want to replace a shape or inline shape ? This is a big difference!

For an inline shape there are plenty of examples on the net. For a shape you can do like this :

    private object missing = System.Reflection.Missing.Value;
    .....other code.....



        foreach (Microsoft.Office.Interop.Word.Shape s in wordApp.ActiveDocument.Shapes)
        {

            if (s.AlternativeText.ToUpper().Contains("FOTO"))
            {
                object A = s.Anchor;
                Shape new = Brief.Shapes.AddPicture(@"mynewpicture.jpg", ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,ref A);
                new.Top = s.Top;
                new.Left = s.Left;
                new.Width = s.Width;
                new.Height = s.Height;
                s.Delete();
            }
        }
