如何测试字符串是否包含列表中的项目？

Question

Say I have a string:

var s = "z_cams_c_ecmf_20160704120000_prod_fc_ml_012_go3.nc";

and say I have a list of strings:

var items = new List<string>(){"fc", "an"};

How can I test if s contains either fc or an ?

I don't want to loop over items and test each case because I am looking for multiple conditions. For example, I will also want to test if s contains "prod" or "rean" or "test".

I suppose I could throw all my conditions ( fc , an , prod , rean , test , etc...) into single list and iterate over each of them, but it doesn't feel right, given the user must supply JSON which is deseralized into an object with various lists for condition matching.

I suppose I am looking for something like the answer seen here , but I do not know what Mdd LH is...

LINQ also uses loops, but you don't see them ;-)

bool contains = items.Any(s.Contains);

If you want to ignore the case(so upper or lowercase letters):

contains = items.Any(i => s.IndexOf(i, StringComparison.InvariantCultureIgnoreCase) >= 0);
