從IronZIP版本2024.3.3開始,此問題已解決。
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
對於較舊的IronZIP版本,特別是2024.3.3版本之前的版本,存在已知的許可問題:
- 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="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,我們可以使用ConfigurationManager檢索許可證金鑰值並將其傳遞給IronZIP屬性。
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

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;指令允許存取設定文件,例如Web.config。ConfigurationManager.AppSettings["IronZip.LicenseKey"]檢索儲存在appSettings部分中的許可證金鑰Web.config。IronZip.License.LicenseKey = licenseKey;將檢索到的金鑰指派給IronZIP函式庫,以避免許可例外情況。Console.WriteLine()語句向開發者提供回饋,表示許可證金鑰申請流程已成功完成。
