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
}
I think you want Any:
if (myList.Any(str => str.Contains("Mdd LH")))
It's well worth becoming familiar with the LINQ standard query operators; I would usually use those rather than implementation-specific methods (such as List<T>.ConvertAll) unless I was really bothered by the performance of a specific operator. (The implementation-specific methods can sometimes be more efficient by knowing the size of the result etc.)
IndexOf instead, passing in a StringComparison. If that's not enough detail, please ask a new question (after searching for existing ones, of course).string.Contains than about Any. See learn.microsoft.com/en-us/dotnet/api/…That should be easy enough
if( myList.Any( s => s.Contains(stringToCheck))){
//do your stuff here
}
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.
LINQ Any() would do the job:
bool contains = myList.Any(s => s.Contains(pattern));
Determines whether any element of a sequence satisfies a condition
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")
