C# 将Word文档转换为HTML

发布：2020/3/2 21:21:57作者：管理员来源：本站浏览次数：1121

日常生活中，我们总是在Word中进行文字的编辑，它不仅能够保存Text文本，还可以保存文本的格式等等。那么如果我要将一Word文档上的内容展示在网页上，该怎么做呢？这里我提供了一个小工具，你可以将Word转换为Html，需要显示的话，可以直接访问该Html，废话不多说，下面看代码。

页面代码：

[html] view plain copy

<SPAN style="FONT-SIZE: 18px"><div>
<input id="File1" type="file" runat="server"/>
<asp:Button ID="btnConvert" runat="server" Text="转换" OnClick="btnConvert_Click" />
</div></SPAN>



	
	
		
		
			
			
				<div>
			

		

	

	
		
		
			
			
				<input id="File1" type="file" runat="server"/>
			

		

	

	
		
		
			
			
				<asp:Button ID="btnConvert" runat="server" Text="转换" OnClick="btnConvert_Click" />
			

		

	

	
		
		
			
			
				</div>

效果图：

转换后的Html文件

这样就可以简单的在Html中展示word文档中的内容，而不需要在自己进行编辑了。当然，如果有需要的话，可以将转换的Html的路径存入数据库，根据不同的条件直接进行访问。
