c# - 反序列化到列表

Question

我正在使用 XmlSerializer.Serialize 和 XmlSerializer.Deserialize 我有一个 MetricResult 类:

public   class Metricresult
{
        public string metric;
        public string newvalue;
        public string deltavalue;

}

我正在计算一些结果，这些结果将存储在:

List<Metricresult> metricresults = new List<Metricresult>();

我成功地将这个列表更改为 xml 文件，在另一个项目中我需要反序列化这个列表但是抛出了一个异常:

there-is-an-error-in-xml-document-0-0-during-deserialization

xml文件

Answer 1

奇怪，因为以下对我来说非常好:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Xml;
using System.Xml.Serialization;

public class MetricResult
{
    public string Metric { get; set; }
    public string NewValue { get; set; }
    public string DeltaValue { get; set; }

}

class Program
{
    static void Main()
    {
        // define some metric results to serialize
        var metricResults = new[] 
        { 
            new MetricResult { Metric = "metric 1", NewValue = "new value 1", DeltaValue = "delta 1" },
            new MetricResult { Metric = "metric 2", NewValue = "new value 2", DeltaValue = "delta 2" },
            new MetricResult { Metric = "metric 3", NewValue = "new value 3", DeltaValue = "delta 3" },
        }.ToList();
        var serializer = new XmlSerializer(metricResults.GetType());

        using (var writer = XmlWriter.Create("metrics.xml"))
        {
            // serialize the metric results we defined previously to metrics.xml
            serializer.Serialize(writer, metricResults);
        }

        using (var reader = XmlReader.Create("metrics.xml"))
        {
            // read metrics.xml and deserialize back
            metricResults = (List<MetricResult>)serializer.Deserialize(reader);
            foreach (var result in metricResults)
            {
                Console.WriteLine("metric: {0}, new value: {1}, delta: {2}", result.Metric, result.NewValue, result.DeltaValue);
            }
        }
    }
}

和 metrics.xml 看起来符合预期:

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfMetricResult xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <MetricResult>
    <Metric>metric 1</Metric>
    <NewValue>new value 1</NewValue>
    <DeltaValue>delta 1</DeltaValue>
  </MetricResult>
  <MetricResult>
    <Metric>metric 2</Metric>
    <NewValue>new value 2</NewValue>
    <DeltaValue>delta 2</DeltaValue>
  </MetricResult>
  <MetricResult>
    <Metric>metric 3</Metric>
    <NewValue>new value 3</NewValue>
    <DeltaValue>delta 3</DeltaValue>
  </MetricResult>
</ArrayOfMetricResult>
