C# 使用LINQ生成Highchart列表数据

我有一个文章数据列表

list

输入数据

List<Article> input = new List<Article>
        {
            new Article { Author = "author1", ReadingNumber = 49, LikeNumber = 55, ForwardingNumber = 21 },
            new Article { Author = "author1", ReadingNumber = 11, LikeNumber = 35, ForwardingNumber = 79 },
            new Article { Author = "author2", ReadingNumber = 25, LikeNumber = 77, ForwardingNumber = 39 },
        };

我已经厌倦了使用linq和Foreach方法来生成数据：

var authorData=
    (from a in articleList
     group a by a.Author into g
     select new {
       Author = g.Key,
       TotalReading = g.Sum(a=>a.ReadingNumber),
       TotalLikes = g.Sum(a=>a.LikeNumber),
       .......
    }).ToList()

然后我使用

ForEach

方法来获取我需要的每个属性

               var totalReading = new AuthorData()
                {
                    name = "TotalReading",
                    data = new List<string>()
                };
                authorData.ForEach(a => totalRead.data.Add(a.TotalRead.ToString()));

var totalReading=new AuthorData（）
{
name=“TotalReading”，
数据=新列表（）
};
authorData.ForEach（a=>totalRead.data.Add（a.totalRead.ToString（））；

最后我把它们组合成结果

var result =
 {
    Authors=authorData.Select(a=>a.Author).ToList(),
    series = new List<AuthorData>{totalReading,totalLike,totalForwrad.....}
}

var结果=
{
Authors=authorData.Select（a=>a.Author.ToList（），
series=新列表{totalReading、TotalIke、totalForwrad….}
}

我觉得很复杂。如何简化此解决方案？

不幸的是，您没有指定您的输入是什么以及为什么它应该看起来像预期的输出。但我想这个解决方案应该可以建立您的预期输出。我使用反射来构建它。如果添加或删除任何整数属性，它们将自动添加或从输出字符串中删除

编辑：在你编辑了你的问题之后，我发现你需要计算财产的总和。这在你最初的问题中并不清楚。这是更新的代码：

List<Article> input = new List<Article>
{
    new Article { Author = "author1", ReadingNumber = 49, LikeNumber = 55, ForwardingNumber = 74 },
    new Article { Author = "author1", ReadingNumber = 141, LikeNumber = 78, ForwardingNumber = 38 },
    new Article { Author = "author2", ReadingNumber = 106, LikeNumber = 38, ForwardingNumber = 39 },
};
        
var grouped = input.GroupBy(x => x.Author).Select(x => new
{
    Author = x.Key,
    TotalReadingNumber = x.Sum(y=>y.ReadingNumber),
    TotalLikeNumber = x.Sum(y=>y.LikeNumber),
    TotalForwardingNumber = x.Sum(y=>y.ForwardingNumber),
}).ToList();
    
StringBuilder output = new StringBuilder();
output.AppendLine("xAxis: {");
output.AppendLine("categories: [");
output.AppendLine(string.Join(",", input.Select(x => $"'{x.Author}'")));
output.AppendLine("]");
output.AppendLine("},"); 
output.Append("series: [");
bool first = true;
foreach(var property in grouped.GetType().GetGenericArguments().First().GetProperties().Where(x => x.PropertyType == typeof(int)))
{
    if(!first)
    {
        output.Append(", ");
    }
    output.AppendLine("{");
    output.AppendLine("name: 'Total" + property.Name + "',");
    output.AppendLine("data: [" + string.Join(",", grouped.Select(x => property.GetValue(x))) + "]");
    output.Append("}");
    first = false;
}
output.AppendLine("]");

这是一个很有前途的解决方案，但我想将结果作为Json字符串保存到数据库中，这样我就可以在另一个控制器中读取它并将其返回到前端。你能不能检查一下我更新的代码，看看使用反射是否能得到类似的结果。我更新了答案。现在它应该与您的问题相匹配了。您好@ichPotatodeCXY，您使用了highcharts标记，但问题似乎不是关于图表，而是关于数据。如果您对Highcharts有问题，请提供一个带有硬编码示例数据的演示。
var result =
 {
    Authors=authorData.Select(a=>a.Author).ToList(),
    series = new List<AuthorData>{totalReading,totalLike,totalForwrad.....}
}

List<Article> input = new List<Article>
{
    new Article { Author = "author1", ReadingNumber = 49, LikeNumber = 55, ForwardingNumber = 74 },
    new Article { Author = "author1", ReadingNumber = 141, LikeNumber = 78, ForwardingNumber = 38 },
    new Article { Author = "author2", ReadingNumber = 106, LikeNumber = 38, ForwardingNumber = 39 },
};
        
var grouped = input.GroupBy(x => x.Author).Select(x => new
{
    Author = x.Key,
    TotalReadingNumber = x.Sum(y=>y.ReadingNumber),
    TotalLikeNumber = x.Sum(y=>y.LikeNumber),
    TotalForwardingNumber = x.Sum(y=>y.ForwardingNumber),
}).ToList();
    
StringBuilder output = new StringBuilder();
output.AppendLine("xAxis: {");
output.AppendLine("categories: [");
output.AppendLine(string.Join(",", input.Select(x => $"'{x.Author}'")));
output.AppendLine("]");
output.AppendLine("},"); 
output.Append("series: [");
bool first = true;
foreach(var property in grouped.GetType().GetGenericArguments().First().GetProperties().Where(x => x.PropertyType == typeof(int)))
{
    if(!first)
    {
        output.Append(", ");
    }
    output.AppendLine("{");
    output.AppendLine("name: 'Total" + property.Name + "',");
    output.AppendLine("data: [" + string.Join(",", grouped.Select(x => property.GetValue(x))) + "]");
    output.Append("}");
    first = false;
}
output.AppendLine("]");
