从IronZIP版本2024.3.3开始,该问题已得到解决。
Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronZip must be licensed for development.
Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronZip must be licensed for development.
SHELL
对于较旧的 IronZIP 版本,特别是2024.3.3版本之前的版本,存在已知的许可问题:
- ASP.NET项目
- .NET Framework版本 >= 4.6.2
存储在 Web.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="IronZip.LicenseKey" value="IRONZIP.MYLICENSE.KEY.1EF01"/>
</appSettings>
...
</configuration>
<configuration>
...
<appSettings>
<add key="IronZip.LicenseKey" value="IRONZIP.MYLICENSE.KEY.1EF01"/>
</appSettings>
...
</configuration>
XML
使用上面提供的 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.Configuration;
class Program
{
static void Main()
{
// Retrieve the license key from the web.config 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.Configuration;
class Program
{
static void Main()
{
// Retrieve the license key from the web.config 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
Friend Class Program
Shared 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 Class

using System.Configuration;指令允许访问配置文件,例如Web.config。ConfigurationManager.AppSettings["IronZip.LicenseKey"]检索存储在appSettings部分中的许可证密钥Web.config。IronZip.License.LicenseKey = licenseKey;将检索到的密钥分配给IronZIP库,以避免许可例外情况。Console.WriteLine()语句向开发者提供反馈,表明许可证密钥申请流程已成功完成。
