如何使用Linq确定此字符串是否以值EndsWith(来自集合)?

问题描述

我正在尝试查找字符串值EndsWith是否是另一个字符串.此其他字符串"是集合中的值.我正在尝试将其作为字符串的扩展方法.

i'm trying to find out if a string value EndsWith another string. This 'other string' are the values from a collection. I'm trying to do this as an extension method, for strings.

例如

var collection = string[] { "ny", "er", "ty" };
"Johnny".EndsWith(collection); // returns true.
"Fred".EndsWith(collection); // returns false.

推荐答案

var collection = new string[] { "ny", "er", "ty" };

var doesEnd = collection.Any("Johnny".EndsWith);
var doesNotEnd = collection.Any("Fred".EndsWith);

您可以创建一个字符串扩展名以隐藏Any

You can create a String extension to hide the usage of Any

public static bool EndsWith(this string value, params string[] values)
{
    return values.Any(value.EndsWith);
}

var isValid = "Johnny".EndsWith("ny", "er", "ty");
