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：
