用文本填充Word文档（使用样式和全部进行修改）使用c＃创建合同文档

Question

this is the picture of sample i have to create . 我要创建一个Word文档并用文本填充它，此文档应看起来像合同Word文件。它应该具有其样式和各种内容的段落（例如标题的页面），并且在最后一页应该具有 文件印章。任何人都可以提供材料或代码吗？

    object oCollapseEnd = Word.WdCollapseDirection.wdCollapseEnd;
doc.Paragraphs.Add();
Word.Range objRange = doc.Content;
objRange.Collapse(ref oCollapseEnd);

objRange.Text = "Bold text aligned center" + Environment.NewLine;
objRange.Bold = 1;
objRange.Paragraphs.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;
objRange.Collapse(ref oCollapseEnd);

objRange.Text = "Regular text aligned left" + Environment.NewLine;
objRange.Paragraphs.Alignment = Word.WdParagraphAlignment.wdAlignParagraphLeft;
objRange.Bold = 0;
objRange.Collapse(ref oCollapseEnd);

objRange.Text = "Regular text aligned center\nwith something on the next line" + Environment.NewLine;
objRange.Paragraphs.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;
objRange.Bold = 0;
objRange.Collapse(ref oCollapseEnd);

objRange.Text = "Regular text aligned left, with some ";
objRange.Collapse(ref oCollapseEnd);
objRange.Text = "Bold text here";
objRange.Bold = 1;
objRange.Collapse(ref oCollapseEnd);
objRange.Text = "\nand some regular text on next line" + Environment.NewLine;
objRange.Paragraphs.Alignment = Word.WdParagraphAlignment.wdAlignParagraphLeft;
objRange.Bold = 0;
