自 IronPDF 版本 2024.3.3 起,该问题已得到 解决。
Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronPDF must be licensed for development.
对于旧的 IronPDF 版本,特别是介于版本 2023.4.4 和 2024.3.3 之间的版本,已知存在一个许可证问题:
- ASP.NET项目
- .NET Framework版本 >= 4.6.2
存储在 Web.config 文件中的密钥不会被产品读取和使用。
解决方法
为了解决这个问题,建议使用代码中的ConfigurationManager从 Web.config 文件中检索许可证密钥,然后将其应用于 License.LicenseKey 属性。
示例:
<configuration>
...
<appSettings>
<add key="IronPdf.LicenseKey" value="IRONPDF-MYLICENSE-KEY-1EF01"/>
</appSettings>
...
</configuration>
<configuration>
...
<appSettings>
<add key="IronPdf.LicenseKey" value="IRONPDF-MYLICENSE-KEY-1EF01"/>
</appSettings>
...
</configuration>
XML
通过上面提供的 XML 文件,我们可以使用 ConfigurationManager 来检索许可密钥值,并将其传递给 IronPdf.License.LicenseKey 属性。
using System.Configuration;
class Program
{
static void Main()
{
// Retrieve the license key from the Web.config file
string licenseKey = ConfigurationManager.AppSettings["IronPdf.LicenseKey"];
// Apply the license key to the IronPdf library
IronPdf.License.LicenseKey = licenseKey;
// Additional processing can continue here
}
}
using System.Configuration;
class Program
{
static void Main()
{
// Retrieve the license key from the Web.config file
string licenseKey = ConfigurationManager.AppSettings["IronPdf.LicenseKey"];
// Apply the license key to the IronPdf library
IronPdf.License.LicenseKey = licenseKey;
// Additional processing can continue here
}
}
Imports System.Configuration
Friend Class Program
Shared Sub Main()
' Retrieve the license key from the Web.config file
Dim licenseKey As String = ConfigurationManager.AppSettings("IronPdf.LicenseKey")
' Apply the license key to the IronPdf library
IronPdf.License.LicenseKey = licenseKey
' Additional processing can continue here
End Sub
End Class
