報表生成器成功案例：C#調用FastReport控件示例

FastReport .Net是適用於Windows Forms，ASP.NET，MVC和.NET Core的全功能報表解決方案。它可以在Microsoft Visual Studio 2005-2019中使用。支持.Net Framework 2.0-4.x，.NET Core 3.0及以上版本。

在FastReport .NET 2021.1的新版本中，我們實現了對.NET 5的支持。添加了新條形碼-Deutsce Post Leitcode。將RTF轉換爲報告對象的算法已得到顯着改進。並且還添加了用於轉換數字的新功能。歡迎下載體驗。
