How Can I Efficiently Check if a String Contains Any or All Substrings from a String Array in C#?

Verifying String Containment Within an Array Using C#

In C#, you can verify whether a string contains any word from a given string array efficiently. Consider the following scenario:

string stringToCheck = "text1text2text3";

string[] stringArray = { "text1", "someothertext", etc... };

Your goal is to determine if stringToCheck contains any substring present within stringArray.

Solution:

To accomplish this task, utilize the Any method from the System.Linq namespace:

if(stringArray.Any(stringToCheck.Contains))

This code snippet iterates through each element s in stringArray and calls stringToCheck.Contains(s) to check if stringToCheck contains s. If any of these checks return true, the Any method returns true, indicating that stringToCheck contains at least one substring from the array.

Alternative:

If you want to check if stringToCheck contains all the substrings in stringArray, simply replace Any with All:

if(stringArray.All(stringToCheck.Contains))

This ensures that stringToCheck contains every substring present in the array.
