在我的項目（ASP.net MVC）中，我必須以小寫形式返回函數(shù)名稱（我讀入的 CSV 文件）。因為現(xiàn)在我已經(jīng)對函數(shù)進行了分組，并且它返回具有相同名稱的函數(shù)（有時是小寫，有時是大寫）。我不知道如何解決這個問題？//HomeControllerpublic List<DescFunctionDataDTO> DescFunctionData(){ Console.WriteLine("DescFunctionData"); var descItemsStamp = db.ChartDatas .GroupBy(x => new { x.Function }); var descItems = descItemsStamp .Select(x => new DescFunctionDataDTO { function = x.Select(b => b.Function).Distinct(), functionavg = Math.Round(x.Average(y => y.Duration), 2), }) .OrderByDescending(x => x.functionavg) .ToList(); return descItems;}//DTOpublic class DescFunctionDataDTO{ public IEnumerable<string> function { get; set; } public double functionavg { get; set; }}//JS-Filefunction showDescDuration() { $.getJSON(`/Home/DescFunctionData`) .then(data => { console.log(data); $('#rankingMax').find("tr:gt(0)").fadeOut().empty(); var i = 1; for (let item of data) { console.log('loop'); $('<tr>').appendTo('#rankingMax') .append($('<td>').html("#"+i)) .append($('<td>').html(item.function)) .append($('<td>').html(item.functionavg + " ms")); i++; } });}

您可以像這樣使用預(yù)定義函數(shù) string.ToLower() ，
var descItemsStamp = db.ChartDatas
.GroupBy(x => new { x.Function });
var descItems = descItemsStamp
.Select(x => new DescFunctionDataDTO
{
function = x.Select(b => b.Function.ToLower()).Distinct(),
functionavg = Math.Round(x.Average(y => y.Duration), 2),
})
.OrderByDescending(x => x.functionavg)
.ToList();
return descItems;
