SHELL

对于较早版本的IronPrint,特别是那些在2024.3.6之前发布的版本,有一个已知的许可问题在:

  • 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拾取和使用。

变通方法

为了解决此问题,建议在代码中使用ConfigurationManagerWeb.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="IronPrint.LicenseKey" value="IRONPRINT.MYLICENSE.KEY.1EF01"/>
  </appSettings>
...
</configuration>
<configuration>
...
  <appSettings>
    <add key="IronPrint.LicenseKey" value="IRONPRINT.MYLICENSE.KEY.1EF01"/>
  </appSettings>
...
</configuration>
XML

通过上面提供的 XML 文件,我们可以使用ConfigurationManager来检索许可证密钥值,并将其传递给IronPrint.License.LicenseKey属性。

using System.Configuration;

string licenseKey = ConfigurationManager.AppSettings ["IronPrint.LicenseKey"];

IronPrint.License.LicenseKey = licenseKey;
using System.Configuration;

string licenseKey = ConfigurationManager.AppSettings ["IronPrint.LicenseKey"];

IronPrint.License.LicenseKey = licenseKey;
Imports System.Configuration

Private licenseKey As String = ConfigurationManager.AppSettings ("IronPrint.LicenseKey")

IronPrint.License.LicenseKey = licenseKey
