如何在linq中订购商品类别

Question

我有20条记录

我想按Priority字段排序记录.

Priority字段有3个值(High, Medium, Low)

我想High, Medium, Low分别按顺序显示记录中的记录.

var groupedRecords = records.GroupBy(x => x.Priority == "High") // confused here...

注:我想首先所有的高记录,然后中记录和atlast低记录.

Answer 1

为什么不将优先级映射到整数:

  High   -> 1
  Medium -> 2
  Low    -> 3 

所以它可以是这样的:

  var groupedRecords = records.
    OrderBy(x => (x.Priority == "High") 
      ? 1 
      : (x.Priority == "Medium") ? 2 : 3);
