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
using System;
using System.Globalization;
using System.Reflection;
public class Empty { }
class GFG {
public static void Main()
{
try {
object [] obj = {2, 3.4, 'c' , "ram"};
Type[] type = Type.GetTypeArray(obj);
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 e)
{
Console.Write("One or more of the elements in args is null .");
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}

using System.Reflection;
public class Empty {}
class GFG {
public static void Main()

try {
object [] obj = {2, 3.4, 'c' , "ram", null };
Type[] type = Type.GetTypeArray(obj);
Console.WriteLine("Types of the objects in the specified array: ");
for ( int i = 0; i < type.Length; i++)

}
catch (ArgumentNullException e)
{
Console.WriteLine("One or more of the elements in args is null .");
