Write a C# Sharp program to compare a given string with a set of strings.

Sample Solution:-

C# Sharp Code:

using System;

public class TestClass { } // Define a custom TestClass.

public class Example32 
{
    public static void Main()
    {
        // Instantiate a TestClass object.
        var test = new TestClass();

        // Create an array of objects for comparison.
        Object[] objectsToCompare = { test, test.ToString(), 123,
                                      123.ToString(), "some text",
                                      "Some Text" };

        string s = "some text"; // Define a string for comparison.

        // Iterate through each object in the objectsToCompare array.
        foreach (var objectToCompare in objectsToCompare)
        {
            try
            {
                // Attempt to compare the string 's' with the current object.
                int i = s.CompareTo(objectToCompare);
                Console.WriteLine("Comparing '{0}' with '{1}': {2}",
                                  s, objectToCompare, i);
            }
            catch (ArgumentException)
            {
                // Handle the exception if the comparison is invalid.
                Console.WriteLine("Bad argument: {0} (type {1})",
                                  objectToCompare,
                                  objectToCompare.GetType().Name);
            }
        }
    }
}

Sample Output:

Bad argument: TestClass (type TestClass)                                                                      
Comparing 'some text' with 'TestClass': -1                                                                    
                                                                                                              
                                                                                                              
Bad argument: 123 (type Int32)                                                                                
Comparing 'some text' with '123': 1                                                                           
                                                                                                              
Comparing 'some text' with 'some text': 0                                                                     
                                                                                                              
Comparing 'some text' with 'Some Text': -1
