Int32.GetHashCode method is used to get the HashCode for the current Int32 instance.
csharp
csharp
Syntax: public override int GetHashCode (); Return Value: This method returns a 32-bit signed integer hash code.Below programs illustrate the use of the above discussed-method: Example 1:
// C# program to illustrate the
// Int32.GetHashCode() Method
using System;
class GFG {
// Main Method
public static void Main()
{
// Taking Int32 variable
int val = 32523;
// Getting the hash code for Int32
// using GetHashCode() method
int result = val.GetHashCode();
// Display the hashcode
Console.WriteLine("HashCode for Int32 is: {0}",
result);
}
}
Output:
Example 2:
HashCode for Int32 is: 32523
// C# program to illustrate the
// Int32.GetHashCode() Method
using System;
class GFG {
// Main Method
public static void Main()
{
// using result() Method
result(Int32.MinValue);
result(Int32.MaxValue);
}
// result() method
public static void result(int val)
{
// using GetHashCode() method
int code = val.GetHashCode();
// Display the hashcode
Console.WriteLine("HashCode for {0} is {1}",
val, code);
}
}
Output:
Reference:
HashCode for -2147483648 is -2147483648 HashCode for 2147483647 is 2147483647
