This problem has been solved since IronPDF version 2024.3.3.

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

对于旧版本的 IronPdf,特别是介于两个版本之间的版本2023.4.42024.3.3, 在以下内容中存在已知的许可问题:

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

    存储在Web.config文件中的密钥将不会被产品拾取并使用。

变通方法

为了解决此问题,建议在代码中使用 ConfigurationManagerWeb.config 文件中检索许可证密钥,然后将其应用到 License.LicenseKey 属性。

示例:

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

有了上面提供的 XML 文件,我们就可以使用ConfigurationManager来获取许可证密钥值,并将其传递给IronPdf.License.LicenseKey属性。

using System.Configuration;

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

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

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

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

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

IronPdf.License.LicenseKey = licenseKey
