使用Interop C＃格式化Word文档

Question

I am currently trying to add an image, text and then another image. However when I insert the text the first image gets replaced.

var footer = document.Content.InlineShapes.AddPicture(AppDomain.CurrentDomain.BaseDirectory + "Images\\footer.png").ConvertToShape();
footer.WrapFormat.Type = WdWrapType.wdWrapTopBottom;
document.Content.Text = input;
var header = document.Content.InlineShapes.AddPicture(AppDomain.CurrentDomain.BaseDirectory+"Images\\header.png").ConvertToShape();
header.WrapFormat.Type = WdWrapType.wdWrapTopBottom;

How do I keep both images in my document?

Update With Rene's answer this is how the document is being presented.

Answer 1

The property Content is a Range object that covers the complete document. A Range object holds all the stuff that is added.

Setting the Text property replaces all content of the Range including non text-objects.

To insert text and images in a cooperative way use the InsertAfter method, like so:

var footer = document
    .Content
    .InlineShapes
    .AddPicture(AppDomain.CurrentDomain.BaseDirectory + "Images\\footer.png")
     .ConvertToShape();
footer.WrapFormat.Type = WdWrapType.wdWrapTopBottom;

// be cooperative with what is already in the Range present
document.Content.InsertAfter(input);

var header = document
    .Content
    .InlineShapes
    .AddPicture(AppDomain.CurrentDomain.BaseDirectory+"Images\\header.png")
    .ConvertToShape();
header.WrapFormat.Type = WdWrapType.wdWrapTopBottom;

If you want to have more control over where you content appears, you can introduce paragraphs, where each paragraph has its own Range . In that case your code could look like this:

var footerPar = document.Paragraphs.Add();
var footerRange = footerPar.Range;
var inlineshape = footerRange.InlineShapes.AddPicture(AppDomain.CurrentDomain.BaseDirectory + "footer.png");
var footer = inlineshape.ConvertToShape();
footer.Visible = Microsoft.Office.Core.MsoTriState.msoCTrue;
footer.WrapFormat.Type = WdWrapType.wdWrapTopBottom;

var inputPar = document.Paragraphs.Add();
inputPar.Range.Text = input;
inputPar.Range.InsertParagraphAfter();

var headerPar = document.Paragraphs.Add();
var headerRange = headerPar.Range;
var headerShape = headerRange.InlineShapes.AddPicture(AppDomain.CurrentDomain.BaseDirectory + "header.png");
var header = headerShape.ConvertToShape();
header.Visible = Microsoft.Office.Core.MsoTriState.msoCTrue;
header.WrapFormat.Type = WdWrapType.wdWrapTopBottom;
