我有一些要序列化的 XML。我的代码运行没有错误，但是序列化不成功，对象是空的而不是用数据填充。该值只是类型值:{OrangeCdToCollectorz.OrangeCd}。我怀疑我的类(class)定义。这也是我正在序列化的类:

这是我的代码，尝试使用几种众所周知的技术对同一 XML 进行反序列化，既作为字符串 const，也来自文件:
XmlSerializer serializer = new XmlSerializer(typeof(OrangeCd));
using (TextReader reader = new StringReader(testData))
{
OrangeCd orangeCd = (OrangeCd)serializer.Deserialize(reader);
}
// Show the dialog and get result.
DialogResult result = openFileDialog1.ShowDialog();
if (result == DialogResult.OK) // Test result.
{
string file = openFileDialog1.FileName;
try
{
var ser = new XmlSerializer(typeof(OrangeCd));
using (var reader = XmlReader.Create(file))
{
var wrapper = (OrangeCd)ser.Deserialize(reader);
XmlDocument _Doc = new XmlDocument();
_Doc.Load(file);
XmlSerializer deserializer = new XmlSerializer(typeof(OrangeCd));
using (TextReader textReader = new StringReader(_Doc.OuterXml))
{
OrangeCd XmlData = (OrangeCd)deserializer.Deserialize(textReader);
}
ser = new XmlSerializer(typeof(OrangeCd));
wrapper = (OrangeCd)ser.Deserialize(new StringReader(_Doc.OuterXml));
_Doc = new XmlDocument();
_Doc.Load(file);
ser = new XmlSerializer(typeof(OrangeCd));
wrapper = (OrangeCd)ser.Deserialize(new XmlNodeReader(_Doc.DocumentElement));
}
}
catch (IOException ioException)
{
Console.WriteLine(ioException.Message); // <-- For debugging use.
}
}

最佳答案
可能您想要做的是反序列化为 OrangeCd.Collection，而不是 OrangeCd
关于c# - 在 C# 中将 Xml 反序列化为对象，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35467531/
总的来说，我对ruby还比较陌生，我正在为我正在创建的对象编写一些rspec测试用例。许多测试用例都非常基础，我只是想确保正确填充和返回值。我想知道是否有办法使用循环结构来执行此操作。不必为我要测试的每个方法都设置一个assertEquals。例如:describeitem,"TestingtheItem"doit"willhaveanullvaluetostart"doitem=Item.new#HereIcoulddotheitem.name.shouldbe_nil#thenIcoulddoitem.category.shouldbe_nilendend但我想要一些方法来使用
我的目标是转换表单输入，例如“100兆字节”或“1GB”，并将其转换为我可以存储在数据库中的文件大小(以千字节为单位)。目前，我有这个:defquota_convert@regex=/([0-9]+)(.*)s/@sizes=%w{kilobytemegabytegigabyte}m=self.quota.match(@regex)if@sizes.include?m[2]eval("self.quota=#{m[1]}.#{m[2]}")endend这有效，但前提是输入是倍数(“gigabytes”，而不是“gigabyte”)并且由于使用了eval看起来疯狂不安全。所以，功能正常，
在控制台中反复尝试之后，我想到了这种方法，可以按发生日期对类似activerecord的(Mongoid)对象进行分组。我不确定这是完成此任务的最佳方法，但它确实有效。有没有人有更好的建议，或者这是一个很好的方法？#eventsisanarrayofactiverecord-likeobjectsthatincludeatimeattributeevents.map{|event|#converteventsarrayintoanarrayofhasheswiththedayofthemonthandtheevent{:number=>event.time.day,:event=>ev
我有一个对象has_many应呈现为xml的子对象。这不是问题。我的问题是我创建了一个Hash包含此数据，就像解析器需要它一样。但是rails自动将整个文件包含在.........我需要摆脱type="array"和我该如何处理？我没有在文档中找到任何内容。 最佳答案 我遇到了同样的问题；这是我的XML:我在用这个:entries.to_xml将散列数据转换为XML，但这会将条目的数据包装到中所以我修改了:entries.to_xml(root:"Contacts")但这仍然将转换后的XML包装在“联系人”中，将我的XML代码修改为
我有一个表单，其中有很多字段取自数组(而不是模型或对象)。我如何验证这些字段的存在？solve_problem_pathdo|f|%>... 最佳答案 创建一个简单的类来包装请求参数并使用ActiveModel::Validations。#definedsomewhere,atthesimplest:require'ostruct'classSolvetrue#youcouldevencheckthesolutionwithavalidatorvalidatedoerrors.add(:base,"WRONG!!!")unlesss
好的，所以我的目标是轻松地将一些数据保存到磁盘以备后用。您如何简单地写入然后读取一个对象？所以如果我有一个简单的类classCattr_accessor:a,:bdefinitialize(a,b)@a,@b=a,bendend所以如果我从中非常快地制作一个objobj=C.new("foo","bar")#justgaveitsomerandomvalues然后我可以把它变成一个kindaidstring=obj.to_s#whichreturns""我终于可以将此字符串打印到文件或其他内容中。我的问题是，我该如何再次将这个id变回一个对象？我知道我可以自己挑选信息并制作一个接受该信
如果您尝试在Ruby中的nil对象上调用方法，则会出现NoMethodError异常并显示消息:"undefinedmethod‘...’fornil:NilClass"然而，有一个tryRails中的方法，如果它被发送到一个nil对象，它只返回nil:require'rubygems'require'active_support/all'nil.try(:nonexisting_method)#noNoMethodErrorexceptionanymore那么try如何在内部工作以防止该异常？ 最佳答案 像Ruby中的所有其他对象
我在Rails工作并有以下类(class):classPlayer当我运行时bundleexecrailsconsole然后尝试:a=Player.new("me",5.0,"UCLA")我回来了:=>#我不知道为什么Player对象不会在这里初始化。关于可能导致此问题的操作/解释的任何建议？谢谢，马里奥格 最佳答案 havenoideawhythePlayerobjectwouldn'tbeinitializedhere它没有初始化很简单，因为你还没有初始化它!您已经覆盖了ActiveRecord::Base初始化方法，但您没有调
我有一个服务模型/表及其注册表。在表单中，我几乎拥有服务的所有字段，但我想在验证服务对象之前自动设置其中一些值。示例:--服务Controller#创建Action:defcreate@service=Service.new@service_form=ServiceFormObject.new(@service)@service_form.validate(params[:service_form_object])and@service_form.saverespond_with(@service_form,location:admin_services_path)end在验证@ser
这个问题在这里已经有了答案:Railsformattingdate(4个答案)关闭4年前。我想格式化Time.Now函数以显示YYYY-MM-DDHH:MM:SS而不是:“2018-03-0909:47:19+0000”该函数需要放在时间中.现在功能。require‘roo’require‘roo-xls’require‘byebug’file_name=ARGV.first||“Template.xlsx”excel_file=Roo::Spreadsheet.open(“./#{file_name}“,extension::xlsx)xml=Nokogiri::XML::Build
