查询表达式点符号

Question

喜，需要一些帮助来此LINQ查询转换为点记号：

  var productions = 
      from row in data 
      group row by row.PRODUCTION_NAME into gr 
      select new 
      { 
       Group = gr.Key, 
       Jobs = from row in gr 
         orderby row.SortFieldCard 
         group row by row.JOB_NAME into job 
         select new { job.Key, Cards = job } 
      }; 

Answer 1

var productions = data 
    .GroupBy(row => row.PRODUCTION_NAME) 
    .Select(gr => new 
    { 
     Group = gr.Key, 
     Jobs = gr 
      .OrderBy(row => row.SortFieldCard) 
      .GroupBy(row => row.JOB_NAME) 
      .Select(job => new { job.Key, Cards = job }) 
    }); 

Answer 2

嘛。如果你的意思是Linq的流利表示法（你说的“dot net”，并且都是dot net（.NET）），我认为这应该有效：

var productions = data 
    .GroupBy(row => row.PRODUCTION_NAME) 
    .Select(gr => new { 
    Group = gr.Key, 
    Jobs = gr 
     .OrderBy(row => row.SortFieldCard) 
     .GroupBy(row => row.JOB_NAME) 
     .Select(job => new { job.Key, Cards = job}) 
    });
