C#中不区分大小写的字典
要进行比较，忽略大小写，请使用不区分大小写的Dictionary。
在声明字典时，设置以下属性以获取不区分大小写的字典-
StringComparer.OrdinalIgnoreCase
添加这样的属性-
Dictionary <string, int> dict = new Dictionary <string, int> (StringComparer.OrdinalIgnoreCase);
这是完整的代码-
示例
using System;
using System.Collections.Generic;
public class Program {
public static void Main() {
Dictionary <string, int> dict = new Dictionary <string, int> (StringComparer.OrdinalIgnoreCase);
dict.Add("cricket", 1);
dict.Add("football", 2);
foreach (var val in dict) {
Console.WriteLine(val.ToString());
}
// case insensitive dictionary i.e. "cricket" is equal to "CRICKET"
Console.WriteLine(dict["cricket"]);
Console.WriteLine(dict["CRICKET"]);
}
}输出结果
[cricket, 1] [football, 2] 1 1
