[c#] Check if a string within a list contains a specific string with Linq

I have a List<string> that has some items like this:

{"Pre Mdd LH", "Post Mdd LH", "Pre Mdd LL", "Post Mdd LL"}

Now I want to perform a condition that checks if an item in the list contains a specific string. something like:

IF list contains an item that contains this_string

To make it simple I want to check in one go if the list at least! contains for example an item that has Mdd LH in it.

I mean something like:

if(myList.Contains(str => str.Contains("Mdd LH))
{
    //Do stuff
}

Thanks.

Thast should be easy enough

if( myList.Any( s => s.Contains(stringToCheck))){
  //do your stuff here
}

If yoou use Contains, you could get false positives. Suppose you have a string that contains such text: "My text data Mdd LH" Using Contains method, this method will return true for call. The approach is use equals operator:

bool exists = myStringList.Any(c=>c == "Mdd LH")

LINQ Any() would do the job:

bool contains = myList.Any(s => s.Contains(pattern));

Any(), MSDN:

Determines whether any element of a sequence satisfies a condition

Try this:

bool matchFound = myList.Any(s => s.Contains("Mdd LH"));

The Any() will stop searching the moment it finds a match, so is quite efficient for this task.
