C# | Type.GetTypeArray() Method
Type.GetTypeArray() Method is used to get the types of the objects in the specified array.
Syntax: public static Type[] GetTypeArray (object[] args); Here, it takes an array of objects whose types to determine.
Return Value: This method returns an array of Type objects representing the types of the corresponding elements in args.
Exception: This method throws ArgumentNullException if args is null or, One or more of the elements in args is null.
Below programs illustrate the use of Type.GetTypeArray() Method:
Example 1:
csharp
// C# program to demonstrate the // Type.GetTypeArray(Object[]) Method using System; using System.Globalization; using System.Reflection; // Defining class Empty public class Empty { } class GFG { // Main Method public static void Main() { // try-catch block for handling Exception try { // creating and initializing object object [] obj = {2, 3.4, 'c' , "ram"}; // using GetTypeArray() Method Type[] type = Type.GetTypeArray(obj); // Display the Result Console.WriteLine("Types of the objects in the specified array: "); for ( int i = 0; i < type.Length; i++) Console.WriteLine(" {0}", type[i]); } // catch ArgumentNullException here catch (ArgumentNullException e) { Console.Write("One or more of the elements in args is null ."); Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } } |
Output:
Types of the objects in the specified array: System.Int32 System.Double System.Char System.String
Example 2:
csharp
// C# program to demonstrate the // Type.GetTypeArray(Object[]) Method using System; using System.Globalization; using System.Reflection; // Defining class Empty public class Empty {} class GFG { // Main Method public static void Main() { // try-catch block for handling Exception try { // creating and initializing object object [] obj = {2, 3.4, 'c' , "ram", null }; // using GetTypeArray() Method Type[] type = Type.GetTypeArray(obj); // Display the Result Console.WriteLine("Types of the objects in the specified array: "); for ( int i = 0; i < type.Length; i++) Console.WriteLine(" {0}", type[i]); } // catch ArgumentNullException here catch (ArgumentNullException e) { Console.WriteLine("One or more of the elements in args is null ."); Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } } |
Output:
One or more of the elements in args is null. Exception Thrown: System.ArgumentNullException
