Comparing two lists and removing each item that contains an entry from the other list

问题

I'm trying to essentially copy any list items in fileManifest but only those that don't contain in any of the items from exclusionFilters to a newly initialized list.
I haven't figured out an elegant way to do this other than a nested foreach loop.

Does someone by chance have a better solution for this problem? Maybe LINQ?

var fileManifest = new List<string>()
{
   @"C:\Test\Directory1\File1.xml",
   @"C:\Test\Directory1\File2.xml",
   @"C:\Test\Directory1\Directory2\File1.xml",
};

var exclusionFilters = new List<string>()
{
  @"Directory2\"
};

var filteredList = new List<string>();

Expected Output of filteredList:

• C:\Test\Directory1\File1.xml
• C:\Test\Directory1\File2.xml

回答1:

var filteredList = fileManifest.Where(x => exclusionFilters.All(y => !x.Contains(y))).ToList();

Description:

• Enumerable.Where Method: Filters a sequence of values based on a predicate.
• Enumerable.All Method: Determines whether all elements of a sequence satisfy a condition.
• String.Contains(String) Method: Returns a value indicating whether a specified substring occurs within this string.
• Enumerable.ToList Method: Creates a List from an IEnumerable.
