自IronPDF版本2024.3.3起,此問題已解決。
Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronPDF must be licensed for development.
對於較舊的IronPDF版本,特別是2023.4.4到2024.3.3之間的版本,存在已知的授權問題:
- ASP.NET項目
- .NET Framework版本 >= 4.6.2
儲存在 Web.config 檔案中的金鑰不會被產品讀取和使用。
解決方法
為了解決這個問題,建議使用程式碼中的ConfigurationManager從 Web.config 檔案中擷取許可證金鑰,然後將其套用至 License.LicenseKey 屬性。
例子:
<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
使用上面提供的 XML 文件,我們可以使用ConfigurationManager檢索許可證金鑰值並將其傳遞給IronPDF屬性。
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
