ASP.NET----实现网页中查看offic文件,word,ppt等

原理很简单，实现一个树，先获取文件存放文件夹地址，然后遍历每个文档，填入到树节点中去，看下截图效果：

具体看下面代码：

File.cs:

public partial class Files : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if(!this.IsPostBack)
            this.InitTree();
    }

    private void InitTree()
    {
        //清除树节点
        this.trvFiles.Nodes.Clear();
        //实例化根节点
        TreeNode node = new TreeNode();
        node.Text = "简历文件";
        node.Value = "";

        //获取存放Word PPT文件的文件夹路径
        string dicPath = this.Server.MapPath("WordFiles");
        //实例化文件夹对象
        DirectoryInfo dic = new DirectoryInfo(dicPath);
        //循环获取Word文档文件
        foreach (FileInfo file in dic.GetFiles("*.doc"))
        {
            //实例化文件节点
            TreeNode fileNode = new TreeNode();
            //赋值
            fileNode.Text = file.Name;
            fileNode.Value = file.FullName;
            //添加至根节点中
            node.ChildNodes.Add(fileNode);
            continue;
        }

        //循环获取PPT文件
        foreach (FileInfo file in dic.GetFiles("*.ppt"))
        {
            TreeNode fileNode = new TreeNode();
            fileNode.Text = file.Name;
            fileNode.Value = file.FullName;
            node.ChildNodes.Add(fileNode);
            continue;
        }
        //展开文件夹节点
        node.Expand();
        this.trvFiles.Nodes.Add(node);
    }

    protected void trvFiles_SelectedNodeChanged(object sender, EventArgs e)
    {
        //判断选中节点不是根节点
        if (!string.IsNullOrEmpty(this.trvFiles.SelectedNode.Value))
        {
            //拼装打开文件的JavaScript脚本
            string js = "window.frames[0].location.href='{0}';";
             js = string.Format(js, "WordFiles/" + this.trvFiles.SelectedNode.Text);
            //执行脚本  即在DocShow.aspx页面打开相应节点
            this.WriteJS(js);
        }
    }

    protected void WriteJS(string msg)
    {
        string script = string.Format("<script type='text/javascript' language='javascript'>{0}</script>", msg);
        this.ClientScript.RegisterStartupScript(this.GetType(), "alert", script);
    }
    
    protected void AlertMsg(string msg)
    {
        string script = string.Format("<script type='text/javascript' language='javascript'>window.alert('{0}');</script>",msg);
        this.ClientScript.RegisterStartupScript(this.GetType(),"alert",script);
    }

   
}

页面布局：

<body>
    <form id="form1" runat="server">
    <div>
        <table style="border: none; padding: none; margin: none; width: 100%; height: 100%;">
            <tr>
                <td style="width:20%;height:100%;vertical-align:top;">
                    <asp:TreeView ID="trvFiles" runat="server" ImageSet="XPFileExplorer" NodeIndent="15"
                        OnSelectedNodeChanged="trvFiles_SelectedNodeChanged">
                        <ParentNodeStyle Font-Bold="False" />
                        <HoverNodeStyle Font-Underline="True" ForeColor="#6666AA" />
                        <SelectedNodeStyle BackColor="#B5B5B5" Font-Underline="False" HorizontalPadding="0px"
                            VerticalPadding="0px" />
                        <NodeStyle Font-Names="Tahoma" Font-Size="8pt" ForeColor="Black" HorizontalPadding="2px"
                            NodeSpacing="0px" VerticalPadding="2px" />
                    </asp:TreeView>
                </td>
                <td>
                    <iframe style="scroll:auto;width:100%;height:800px;border:none;" src="DocShow.aspx">
                    </iframe>
                </td>
            </tr>
        </table>
    </div>
    </form>
</body>
