linq-to-entities - Linq to Entity 将字符串转换为正确的大小写

Question

当我选择使用 Linq to entity 到正确的大小写时，你能告诉我一个如何转换字符串的例子吗？谢谢

Answer 1

我认为您不需要纯粹的 LINQ。

看看这个例子

string sampleString = "this is a title";
CultureInfo currentCulture = System.Threading.Thread.CurrentThread.CurrentCulture;
TextInfo currentInfo = currentCulture.TextInfo;
sampleString = currentInfo.ToTitleCase(sampleString); 

//output:
//This Is A Title

TextInfo.ToTitleCase Method

所以在 LINQ select 中你可以使用类似的东西

CultureInfo currentCulture = System.Threading.Thread.CurrentThread.CurrentCulture;
TextInfo currentInfo = currentCulture.TextInfo;
List<string> testList = new List<string> { "foo", "bAr", "fOO bar Test tAdA" };
var correct = from s in testList
              select currentInfo.ToTitleCase(s);
