Type.GetHashCode() Method is used to return the hash code for this instance.
csharp
csharp
Syntax: public override int GetHashCode (); Return Value: This method returns the hash code for the current instance.Below programs illustrate the use of Type.GetHashCode() Method: Example 1:
// C# program to demonstrate the
// Type.GetHashCode() Method
using System;
using System.Globalization;
using System.Reflection;
using System.Collections.Generic;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing object of Type
Type objType = typeof(Dictionary<, >);
// Getting hashcode of given type
// using GetHashCode() Method
int hash = objType.GetHashCode();
// Display the Result
Console.Write("Hashcode is {0}", hash);
}
}
Output:
Example 2:
Hashcode is 32340152
// C# program to demonstrate the
// Type.GetHashCode() Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// calling get() method
get(typeof(int));
get(typeof(string));
get(typeof(decimal));
get(typeof(float));
}
// defining get() method
public static void get(Type objType)
{
// Getting hashcode of given type
// using GetHashCode() Method
int hash = objType.GetHashCode();
// Display the Result
Console.WriteLine("Hashcode of {0} is {1}", objType, hash);
}
}
Output:
Reference:
Hashcode of System.Int32 is 18784216 Hashcode of System.String is 18793840 Hashcode of System.Decimal is 19137544 Hashcode of System.Single is 18792864
