C#代碼怎麽將數據庫中的數據導成DOC和PDF格式

微軟從未公開過doc文件格式信息，所以如果妳想將文本保存為doc格式，只有操作word完成。如何開發基於Word的.net程序妳在網上搜索以下，很多。 至於PDF，給妳個簡單的例子：using System;

using System.IO;

using System.Text;

using System.Collections;namespace PDFGenerator

{

/// <summary>

/// Application : Generation of PDF file from text

/// Date : 25th July 2001

static float leadSize = 10.0f;//Create a PDF file.

//PDF on Disk

//PDF in Memory
