Typeof() vs GetType() in C#
Typeof()
The type takes the Type and returns the Type of the argument.
For example: System.Byte for the following −
typeof(byte)
The following is an example −
Example
using System;
class Program {
static void Main() {
Console.WriteLine(typeof(int));
Console.WriteLine(typeof(byte));
}
}Output
System.Int32 System.Byte
GetType()
The GetType() method of array class in C# gets the Type of the current instance.
To get the type.
Type tp = value.GetType();
In the below example, we are checking the int value using the type.
if (tp.Equals(typeof(int)))
Console.WriteLine("{0} is an integer data type.", value)The following is the usage of GetType() method in C#.
Example
using System;
class Program {
public static void Main() {
object[] values = { (int) 100, (long) 17111};
foreach (var value in values) {
Type tp = value.GetType();
if (tp.Equals(typeof(int)))
Console.WriteLine("{0} is an integer data type.", value);
else
Console.WriteLine("'{0}' is not an int data type.", value);
}
}
}Output
100 is an integer data type. '17111' is not an int data type.
