The problem has been resolved as of IronXL version 2024.3.20.

Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronXL must be licensed for development.

針對舊版本的IronXL,特別是那些版本介於 2023.4.132024.3.20,已知存在授權問題於:

  • ASP.NET 專案
  • .NET Framework 版本 >= 4.6.2

    儲存在 Web.config 檔案中的金鑰不會被產品檢索和使用。

變通方法

要解決此問題,建議在程式碼中使用 ConfigurationManagerWeb.config 文件中檢索授權密鑰,然後將其應用於 License.LicenseKey 屬性。

範例:

<configuration>
  ...
  <appSettings>
    <add key="IronXL.LicenseKey" value="IronXL-MYLICENSE-KEY-1EF01"/>
  </appSettings>
  ...
</configuration>
XML

有了上面的 XML 文件,我們可以使用ConfigurationManager來檢索授權金鑰值並將其傳遞給IronXL.License.LicenseKey屬性。

using System.Configuration;

string licenseKey = ConfigurationManager.AppSettings ["IronXL.LicenseKey"];

IronXL.License.LicenseKey = licenseKey;
using System.Configuration;

string licenseKey = ConfigurationManager.AppSettings ["IronXL.LicenseKey"];

IronXL.License.LicenseKey = licenseKey;
Imports System.Configuration

Private licenseKey As String = ConfigurationManager.AppSettings ("IronXL.LicenseKey")

IronXL.License.LicenseKey = licenseKey
