//Sample 1 - Using Labmda Expression 
            String str1 = "XXXwww.msdotnetsupport.blogspot.comXXX";
            foreach (var item in str1.Where(x => x != 'X'))
	        {
    		  Console.Write(item);
	        }



            //Sample 2 - without Labmdas, and using ananymous method.
            String str2 = "XXXwww.msdotnetsupport.blogspot.comXXX";
            foreach (var item in str2.Where<char>(delegate(char x) 
                                                    {
                                                        return x != 'X';
                                                    }))
            {
                Console.Write(item);
            }



//Sample 3
         Now I do not want to use ananymouse delegate method as parameter to Where function
so can anybody can help me how to convert sample2 to sample3 without using anonymous function and map the parameter to below function

public static bool CharCheck(char x)
{
 return x != 'X'
}

foreach (var item in str2.Where<char>(CharCheck))

I think the previous poster meant

foreach (char letter in str2.Where<char>(x=>CharCheck(x)) )

(of course, your exact example could just be Console.Write(str2.Replace("X", string.Empty)) )

Sorry, my mistake.
