该问题已在 IronZip 2024.3.3 版本中得到解决。
Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronZip must be licensed for development.

SHELL
对于较早版本的 IronZip(特别是 2024.3.3 版之前的版本),存在已知的许可问题:
- ASP.NET 项目
- .NET Framework 版本 >= 4.6.2
存储在 Web.co/nfig 文件中的密钥将不会被产品识别并使用。
解决方法
为解决此问题,建议在代码中使用 ConfigurationManager 从 Web.co/nfig 文件中获取许可证密钥,然后将其应用到 License.LicenseKey 属性上。
示例:
<configuration>
...
<appSettings>
<add key="IronZip.LicenseKey" value="IRONZIP.MYLICENSE.KEY.1EF01"/>
</appSettings>
...
</configuration>
<configuration>
...
<appSettings>
<add key="IronZip.LicenseKey" value="IRONZIP.MYLICENSE.KEY.1EF01"/>
</appSettings>
...
</configuration>
XML
利用上文提供的 XML 文件,我们可以使用 ConfigurationManager 检索许可证密钥值,并将其传递给 IronZip.License.LicenseKey 属性。
using System;
using System.Co/nfiguration;
class Program
{
static void Main()
{
// Retrieve the license key from the web.co/nfig appSettings
string licenseKey = ConfigurationManager.AppSettings["IronZip.LicenseKey"];
// Apply the license key to IronZip
IronZip.License.LicenseKey = licenseKey;
// Verify that the license key is set properly
Console.WriteLine("License key applied successfully.");
}
}
using System;
using System.Co/nfiguration;
class Program
{
static void Main()
{
// Retrieve the license key from the web.co/nfig appSettings
string licenseKey = ConfigurationManager.AppSettings["IronZip.LicenseKey"];
// Apply the license key to IronZip
IronZip.License.LicenseKey = licenseKey;
// Verify that the license key is set properly
Console.WriteLine("License key applied successfully.");
}
}
Imports System
Imports System.Configuration
Module Program
Sub Main()
' Retrieve the license key from the web.config appSettings
Dim licenseKey As String = ConfigurationManager.AppSettings("IronZip.LicenseKey")
' Apply the license key to IronZip
IronZip.License.LicenseKey = licenseKey
' Verify that the license key is set properly
Console.WriteLine("License key applied successfully.")
End Sub
End Module

using System.Co/nfiguration;指令允许访问配置文件,例如Web.co/nfig。ConfigurationManager.AppSettings["IronZip.LicenseKey"]会从Web.co/nfig的appSettings部分中检索许可证密钥。IronZip.License.LicenseKey = licenseKey;将检索到的密钥分配给 IronZIP库,以避免许可异常。Console.WriteLine()语句向开发者反馈许可证密钥申请流程已成功完成。
准备开始了吗?
