C# ? Ignore Case and Check if String contains Substring

To ignore case and check if specified substring value is present in the string str , use String.Contains(String, StringComparison) method. Prepare StringComparison object comp with StringComparison.OrdinalIgnoreCase. Call Contains method on the string str and pass the substring value , and string comparison comp objects as arguments.

If the substring is present inside the string, of course ignoring the case, then String.Contains() method returns True. Else, it returns False.

C# Program

using System; class Example {

static void Main(string[] args) { String str = "abcdefgh"; String value = "CD"; StringComparison comp = StringComparison.OrdinalIgnoreCase; Boolean result = str.Contains(value, comp); Console.WriteLine($"Does string contain specified substring? {result}");

} }

Output

Does string contain specified substring? True

Conclusion

In this C# Tutorial, we learned how to check if specified substring is present in a given string while ignoring the case during string comparison.
