In C#, String.Contains() is a string method. This method is used to check whether the substring occurs within a given string or not.
It returns the boolean value. If substring exists in string or value is the empty string (“”), then it returns True, otherwise returns False.
Exception − This method can give ArgumentNullException if str is null.
This method performs the case-sensitive checking. The search will always begin from the first character position of the string and continues until the last character position.
Contains is case sensitive if the string is found it return true else false
static void Main(string[] args){ string[] strs = { "Sachin", "India", "Bangalore", "Karnataka", "Delhi" }; if (strs.Contains("sachin")){ System.Console.WriteLine("String Present"); } else { System.Console.WriteLine("String Not Present"); } Console.ReadLine(); }
String Not Present
static void Main(string[] args){ string[] strs = { "Sachin", "India", "Bangalore", "Karnataka", "Delhi" }; if (strs.Contains("Sachin")){ System.Console.WriteLine("String Present"); } else { System.Console.WriteLine("String Not Present"); } Console.ReadLine(); }
String Present
static void Main(string[] args){ string[] strs = { "Sachin", "India", "Bangalore", "Karnataka", "Delhi" }; var res = strs.Where(x => x == "Sachin").FirstOrDefault(); System.Console.WriteLine(res); Console.ReadLine(); }
Sachin
static void Main(string[] args){ string[] strs = { "Sachin", "India", "Bangalore", "Karnataka", "Delhi" }; foreach (var item in strs){ if (item == "Sachin"){ System.Console.WriteLine("String is present"); } } Console.ReadLine(); }
String is present
