IronPython中的等效代码
本文关键字:代码 IronPython | 更新日期: 2023-09-27 18:23:47
我在C#中得到了一个(琐碎的)代码示例,我现在正试图将其转换为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"license"中。我运行:
Licensing.LicenseKeys.Keys = Array[str]([open('license').read()])
但是得到
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())
但是具有相同的效果。
事实上Licensing.LicenseKeys.Keys需要Array[str],但我不确定@在C#示例中的含义。
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@指定了一个逐字逐句的字符串文字。这意味着不处理转义序列等,并且字符串可能跨越多行。一个原始的三引号字符串应该是等效的文字。
由于读取文件时使用的编码和/或模式,您的初始代码可能会失败。根据文件数据的情况,您可能需要指定打开文件的备用模式(例如,二进制的b),或者使用.NET BCL函数,如file.ReadAllText,您也可以从C#中进行检查。
