How to check whether a string contains a specific character in C#

String contains character

C# Code:


    class Program
    {
        static void Main(string[] args)
        {
            //this section create a string variable.
            string stringVal = "abcde fghi jklmn";

            Console.WriteLine("string..................");
            Console.WriteLine(stringVal);

            //this line check string contains character 'b' or not.
            Boolean resultb = stringVal.Contains('b');

            //this line check string exists character 'z' or not.
            Boolean resultz = stringVal.Contains('z');

            Console.WriteLine("\nstring contains character ('b')?.........");
            Console.WriteLine(resultb);

            Console.WriteLine("\nstring contains character ('z')?...........");
            Console.WriteLine(resultz);
            Console.ReadLine();
        }
    }

class Program

{

static void Main(string[] args)

{

//this section create a string variable.

string stringVal = "abcde fghi jklmn";

Console.WriteLine("string..................");

Console.WriteLine(stringVal);

//this line check string contains character 'b' or not.

Boolean resultb = stringVal.Contains('b');

//this line check string exists character 'z' or not.

Boolean resultz = stringVal.Contains('z');

Console.WriteLine("\nstring contains character ('b')?.........");

Console.WriteLine(resultb);

Console.WriteLine("\nstring contains character ('z')?...........");

Console.WriteLine(resultz);

Console.ReadLine();
