如何用C#编写,向Word的指定位置插入图片,图片版式要求是嵌入型

Question

我的代码如下,可是图片的格式和位置怎么也不对,我想让图片插在数字974后面,另外版式也是不对,,枚举里wdWrapInline和wdWrapNone怎么都是"文字之上"呢?
请问各位大哥,分不多. private void button2_Click(object sender, EventArgs e)

            try

                //创建Word文档
                Word._Application WordApp = new Word.ApplicationClass();
                Word._Document WordDoc = new Word.DocumentClass();
                WordDoc = WordApp.Documents.Add(ref Nothing, ref Nothing, ref Nothing, ref Nothing);//出现提示信息,因为前面必须加_
                WordDoc.Activate();                Word.Paragraph oPara1;
                oPara1 = WordDoc.Content.Paragraphs.Add(ref Nothing);
                oPara1.Range.Text = "1.5吨双层四车四绳罐笼计算方法";
                //oPara1.Range.Font.Bold = 5;
                oPara1.Range.Font.Size = 12;
                oPara1.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;

                oPara2.Range.Text = "荷重：MG1.7-9B  1.5米固定式矿车单重974kg，4辆矿车总重974";//图片插在这个位置（图片是个乘号）

参考一下这个，我觉得应该是wdWrapTopBottom。

Answer 2

wdWrapInline        In line with text. 
wdWrapNone          Behind text. 
wdWrapSquare        Square. 
wdWrapThrough       Through. 
wdWrapTight         Tight. 
wdWrapTopBottom     Top and bottom. 
我的研究结果是wdWrapInline 和wdWrapNone 是一样的.

Answer 3

 ////设置图片浮于文字之上 - 查阅WdWrapType的相关WdWrapType Enumeration
            //cShape.WrapFormat.Type = WdWrapType.wdWrapNone;
            //wdWrapInline        In line with text. 
            //wdWrapNone          Behind text. 
            //wdWrapSquare        Square. 
            //wdWrapThrough      Through. 
            //wdWrapTight        Tight. 
            //wdWrapTopBottom    Top and bottom.   cShape.LockAnchor = 0;                           
                            cShape.WrapFormat.Side = WdWrapSideType.wdWrapBoth;                            ////设置图片浮于文字之上 - 查阅WdWrapType的相关WdWrapType Enumeration
                            cShape.ZOrder(Microsoft.Office.Core.MsoZOrderCmd.msoSendBehindText);
                            cShape.WrapFormat.Type = WdWrapType.wdWrapNone;
