C# Predicate Delegate

Predicate Delegate With An Anonymous Methord

As seen in the following example, you can also use a Predicate delegate with an anonymous method:
Example:

Predicate<string> val = delegate(string str)
{
    if (mystring.Length < 7)
    {
        return true;
    }
    else 
    {
        return false;
    };
    
    val("This is an Example");
}

Must Read IEnumerable vs IQueryable.

Predicate Delegate With The Lambda Expressions

As seen in the following example, you can also utilise a Predicate delegate with lambda expressions:

Predicate<string> val = str = > str.Equals(str.ToLower());
val("This is an Example");
