原文:https://www . geesforgeks . org/c-sharp-type-gethashcode-method/
类型。GetHashCode()方法用于返回这个实例的哈希代码。
语法:public override int GetHashCode();
返回值:该方法返回当前实例的哈希代码。
以下程序说明了类型的使用。GetHashCode() 方法:
例 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:
Hashcode is 32340152
例 2:
// 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:
Hashcode of System.Int32 is 18784216
Hashcode of System.String is 18793840
Hashcode of System.Decimal is 19137544
Hashcode of System.Single is 18792864
