Order by duplicate amount in a list using linq-CodePudding

I have this class:

class Cell
{
    string keyword;
    double bkgColor;
    double keywordColor;
}

I have a list of this class and I want to order it by duplicates of bkgColor using linq. For example: Keywords with background color that has the most keywords assigned, would be at the start of the list etc.

Evey answer is highly appreciated!

CodePudding user response：

Assuming that keyword, bkgColor and keywordColor are public properties of the class Cell. You can use this linq

var result = cells.GroupBy(c => c.bkgColor)
            .OrderByDescending(g => g.Count())
            .SelectMany(g => g.Select(c => c));
