C# - Unchecked statement

In C#, when using the 'unchecked' statement, the program doesn't handle stack overflow exceptions, and it continues to run the code. This can lead to outputs that are not correct. For a clearer explanation, examine the code provided below: 


private void button10_Click(object sender, EventArgs e)
{ 
	uncheckedExample(); 
} 
void uncheckedExample() 
{ 
	int val1 = 2147483647; 
	int val2 = 100; 
	try 
	{ 
		unchecked  
		{  
		  int val3 = val1 + val2;
		  Console.WriteLine(val3); 
		}  
	} 
	catch (Exception ex) 
	{  
		Console.WriteLine(ex.ToString()); 
	}
}

The output shown is incorrect; however, you'll notice that no overflow exception occurs because the 'unchecked' statement is in use.
