[英]Decoding from Base64 in C#
I created XML Document and saved this document as 我创建了XML Document并将此文档保存为
XmlDocument xmlDoc = new XmlDocument();
XmlDeclaration dec = xmlDoc.CreateXmlDeclaration("1.0", "UTF-8", null);
xmlDoc.AppendChild(dec);
XmlTextWriter writer = new XmlTextWriter(fullPath,Encoding.UTF8);
writer.Formatting = Formatting.Indented;
xMLDoc.Save(writer);
writer.Flush();
And then I have encoded this document using Base64 Encoder 然后我使用Base64 Encoder编码了这个文档
The Decoder could not parse XML file. 解码器无法解析XML文件。 I created the decoder myself and got this result
我自己创建了解码器并得到了这个结果
?<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n<ClinicalDocument
xmlns=\"urn:hl7-org:v3\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"
classCode=\"DOCCLIN\" moodCode=\"EVN\" schemaLocation=\"urn:hl7-org:v3
CDA.xsd\">\r\n <typeId extension=\"POCD_HD000040\" root=\"2.16.840.1.113883.1.3
\" />\r\n
Please help me to resolve the issue. 请帮我解决这个问题。 How I have to save the XML file to avoid the issues?
我如何保存XML文件以避免问题? Or How I have to encode to Base 64 to resolve the issue?
或者我如何编码到Base 64来解决问题? I am using base64 encoder to encode xml file.
我使用base64编码器来编码xml文件。 I am requesting document.
我要求提供文件。 it is required to use base64 encoder.
它需要使用base64编码器。 I decoded myself to check where is the problem.
我解码自己检查问题在哪里。 The decoder is Java .
解码器是Java。 They can not parse the xml file I believe because ?< in front of the document.
他们无法解析我认为的xml文件,因为?<在文档前面。
It depends on how you're encoding it, but you should use UTF-8 since the document is declared as such. 这取决于你如何编码它,但你应该使用UTF-8,因为文档是这样声明的。 Here are examples for encoding and decoding:
以下是编码和解码的示例:
See Jon Skeet's answer here: 请参阅Jon Skeet的回答:
C# base64 encoding/decoding with serialization of objects issue C#base64编码/解码与对象序列化问题
To encode: 编码:
public string EncodeStringToBase64(string stringToEncode)
{
return Convert.ToBase64String(Encoding.UTF8.GetBytes(stringToEncode));
}
To decode: 要解码:
public string DecodeStringFromBase64(string stringToDecode)
{
return Encoding.UTF8.GetString(Convert.FromBase64String(stringToDecode));
}
One other option - could be BOM in default Utf-8 stream created by new XmlTextWriter(fullPath,Encoding.UTF8); 另一个选项 - 可能是由新的XmlTextWriter(fullPath,Encoding.UTF8)创建的默认Utf-8流中的BOM;
Consider using second constructor for UTF8 - http://msdn.microsoft.com/en-us/library/s064f8w2.aspx that does not insert BOM into the stream. 考虑使用UTF8的第二个构造函数 - http://msdn.microsoft.com/en-us/library/s064f8w2.aspx ,它不会将BOM插入流中。
