检查字典是否包含子字符串? [英] Check if dictionary contains substring?

问题描述

说我有两个带有以下键值对的字典:

Say I have two dictionaries with the following key value pairs:

1, "Hello"
2, "Example"

另一本字典如下:

1, "HelloWorld"
2, "Example2"

我想确定这些词典中是否包含子字符串"hello".
dictionary.ContainsValue("Hello")将适用于第一个示例，但不适用于第二个示例.如何检查字典中所有值中是否存在子字符串?

I want to find out if these dictionaries contain the substring "hello" within them.
dictionary.ContainsValue("Hello") will work for the first example but not the second one. How can I check for existence of a substring in all values in a dictionary?

推荐答案

只需使用Any来检查包含"Hello"的第一个值

Just use Any to to check for the first Value that contains "Hello"

dictionary.Any(kvp=>kvp.Value.Contains("Hello"))
