获取字符串中包含的实例列表中的计数 [英] Get Count in List of instances contained in a string

问题描述

我有一个字符串，最多包含9个 unique 数字，范围从1到9(myString)，例如"12345"

I have a string containing up to 9 unique numbers from 1 to 9 (myString) e.g. "12345"

我有一个字符串列表{{1}，{" 4}(myList)等.

I have a list of strings {"1"}, {"4"} (myList) .. and so on.

我想知道字符串(myString)中的列表(myList)中包含多少个实例，在上面的示例中，它将返回2.

I would like to know how many instances in the string (myString) are contained within the list (myList), in the above example this would return 2.

类似

count = myList.Count(myList.Contains(myString));

如果需要，我可以将myString更改为列表.

I could change myString to a list if required.

非常感谢

乔

我会尝试以下操作:

count = mylist.Count(s => myString.Contains(s));
