由于XML是字符串，解压几乎肯定需要二进制数据作为输入，因此StreamData
属性的值必须是二进制数据的ASCII/字符串编码表示形式。这可以使用简单的bin-2-hex表示法，但从问题中提供的示例来看，它更可能是base64或类似的表示法
提供XML的任何人都应该能够为您确认编码
在任何情况下，我们都可以相当肯定StreamData
必须采用字符串编码形式，因为否则二进制数据将包含会导致无效XML文件的值（例如值为0的字节等）
在这种情况下，您的问题是Encoding.UTF8.GetBytes（）
将传递的数据简单地解释为字节数组。也就是说，它希望给定的字节是有效UTF8编码字符串的一部分。它不进行从十六进制字符到二进制字节等的任何转换
也就是说，使用一个非常简单的示例，如果您的StreamData
是一个值为“000102”
的字符串，那么您的代码当前将生成一个byteStream
，其内容由6（六）个字节组成，值如下：
StreamData : '0' '0' '0' '1' '0' '2'
bytes : [30][30][30][31][30][32] (hexadecimal byte values)
StreamData : '00''01''02'
bytes : [00][01][02] (hexadecimal byte values)
当您可能期望的是一个3（三）字节的流，其值对应于StreamData
，如下所示：
StreamData : '0' '0' '0' '1' '0' '2'
bytes : [30][30][30][31][30][32] (hexadecimal byte values)
StreamData : '00''01''02'
bytes : [00][01][02] (hexadecimal byte values)
i、 e.在将StreamData
字符串传递到Decompress（）例程之前，您需要将其正确解码为内存中的二进制表示形式，该例程当前正在抱怨，因为它提供的二进制数据不是有效的压缩数据
您需要在StreamData
中确认二进制数据的编码，并应用适当的解码以获得该数据的二进制表示形式，然后再将其传递到Decompress（）例程，而不是原始/原始字符串表示形式。没有看到创建文件的代码，或者是一个示例文件，我们必须猜测您实际做了什么。我用xmlI更新了它。我有一种感觉，这将归结为zlib头不兼容的问题。解码base64并检查标头。获取Delphi代码会有帮助！不幸的是，我没有访问Delphi代码的权限。我确实为zlib.net添加了一个nuget，但没有使用它，对此我有点困惑。我唯一能确定的是，无论是谁压缩它，都会通过Delphi/Pascal使用Stream.WriteComponent。谢谢-我将尝试您推荐的方法。这里是streamdata属性的一个相当大的部分：streamdata="Bhl0BevzdGltyxRPBMCudGxPxPxBwf0Aw5NbGtuy3HucMvLtGlzDaizBagUy3HucMvLtGlzDjHbMrZagacQyFqmFuzDag1RjFryzWvTxBxBw9Aw9Aw9UgGaUgGaUgGaUgAw9UgGaUgGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbGbG29SSW5KZXGCBGIABGHGHSB3DJBMRLEAGAGAGUCUJHMI将流数据属性放在我的示例中，如果该帮助在我看来像base64。提供XML文件的人应该能够为您确认。：）嘿，我终于让它像你推荐的那样工作了，但现在我不知道该怎么处理它返回的内容：“tpf0tpscxestimatingtreelistcolumnscaption.TextNameDataBinding.ValueTypeStringWidth8Position.ColIndex”它只是一个乱码字符串。。。
