Silverlight visifire Chart图表下载到PPT文件中

一、Silverlight xaml.cs文件

1、 //下载图表
        private void btnDown_Click(object sender, RoutedEventArgs e)
        {
            DBServiceClient svc = new DBServiceClient();
            svc.ShowPresentationAsync();
            svc.ShowPresentationCompleted += new EventHandler<ShowPresentationCompletedEventArgs>(svc_ShowPresentationCompleted);
        }

2、//下载图表
        private void svc_ShowPresentationCompleted(object sender, ShowPresentationCompletedEventArgs e)
        {
         string strUri = Application.Current.Host.Source.AbsoluteUri.Substring(0, Application.Current.Host.Source.AbsoluteUri.IndexOf("/ClientBin")) + "/Temp/" + "Silverlight图表.ppt";
          strUri = "window.location.href='" + strUri + "';";
          System.Windows.Browser.HtmlPage.Window.Eval(strUri);
            //删除Excel临时文件
            DBServiceClient svc = new DBServiceClient();
            svc.DeleteExcelReportAsync();
        }

二、WCF

添加引用

using Microsoft.Office.Core;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using Graph = Microsoft.Office.Interop.Graph;
using System.Runtime.InteropServices;

在所属项目中添加引用，COM选项卡下：

Microsoft.Office.Interop.PowerPoint

Microsoft Excel 12.0 Object Library

Microsoft Graph 12.0 Object Library

Microsoft PowerPoint 12.0 Object Library

Microsoft…………Word文档

添加之后可能会报错：

检索COM 类工厂中CLSID 为{91493442-5A91-11CF-8700-00AA0060263B} 的组件失败，原因是出现以下错误: 80070005 拒绝访问

电脑要进行设置

1：在服务器上安装office的Excel软件.

2：在"开始"->"运行"中输入dcomcnfg.exe启动"组件服务"

3:依次双击"组件服务"->"计算机"->"我的电脑"->"DCOM配置"

4:在"DCOM配置"中找到"Microsoft Excel 应用程序",在它上面点击右键,然后点击"属性",弹出"Microsoft Excel 应用程序属性"对话框

5:点击"标识"标签,选择"交互式用户"

6:点击"安全"标签,在"启动和激活权限"上点击"自定义",然后点击对应的"编辑"按钮,在弹出的"安全性"对话框中填加一个"NETWORK SERVICE"用户(注意要选择本计算机名),并给它赋予"本地启动"和"本地激活"权限.

7:依然是"安全"标签,在"访问权限"上点击"自定义",然后点击"编辑",在弹出的"安全性"对话框中也填加一个"NETWORK SERVICE"用户,然后赋予"本地访问权限

（6步骤，可以点击“高级”--“查找”进行添加用户，还要添加IIS-……用户，权限也要有“远程…”权限；DCOM配置要对MicrosoftPPt，word,Excel……都要进行配置）

项目引用中会增加：

Microsoft.Office.Core

Microsoft.Office.Interop.PowerPoint

Microsoft.Office.Interop.Excel

Microsoft.Office.Interop.Graph

Microsoft.Office.Interop.Word

所属项目版本号会增加：
