我在 C# 中提供了一个（简单的）代码示例，我现在正尝试将其转换为 IronPython：

Clearcore2.Licensing.LicenseKeys.Keys = new[] {
          @"<?xml version=""1.0"" encoding=""utf-8""?>
            <license_key>
                <company_name>Company </company_name>
                <product_name>ProcessingFramework</product_name>
                <features>WiffReaderSDK</features>
                <key_data>
                    2F923C31D1E7E16B191EF2F87DCA7F15831A3F18DED11E05582A98822==
                </key_data>
            </license_key>"};

实际的许可证密钥存储在文件“许可证”中。我跑：

Licensing.LicenseKeys.Keys = Array[str]([open('license').read()])

但得到

System.TypeInitializationException: The type initializer for 'Clearcore2.Data.WiffReader.WiffSampleRun' threw an exception. ---> Clearcore2.Licensing.LicenseKeyFormatException: License key can't be parsed! ---> System.ArgumentNullException: String reference not set to an instance of a String.

我也试过

Licensing.LicenseKeys.Keys = Array[str](open('license').read())

但效果相同。

实际上 Licensing.LicenseKeys.Keys 需要 Array[str]，但我不确定 C# 示例中的 @ 是什么意思。

IronPython 中 C# 示例的等效代码是什么？

IronPython 中的一个近似等价物是

Clearcore2.Licensing.LicenseKeys.Keys = Array[str]([r"""<?xml version=""1.0"" encoding=""utf-8""?>
            <license_key>
                <company_name>Company </company_name>
                <product_name>ProcessingFramework</product_name>
                <features>WiffReaderSDK</features>
                <key_data>
                    2F923C31D1E7E16B191EF2F87DCA7F15831A3F18DED11E05582A98822==
                </key_data>
            </license_key>"""])

C# 中的@指定逐字字符串文字。这意味着不处理转义序列等，并且字符串可能跨越多行。原始的三引号字符串应该是等效的文字。

由于您读取文件的编码和/或模式，您的初始代码可能会失败。根据文件数据应该发生的情况，您可能希望指定另一种打开文件的模式（例如b表示binary）或使用类似File.ReadAllText的 .NET BCL 函数，您也可以从 C# 中检查该函数。
