C# | Type.GetTypeFromHandle() Method

Last Updated : 20 May, 2019

Type.GetTypeFromHandle() Method is used to get the type referenced by the specified type handle.

Syntax: public static Type GetTypeFromHandle (RuntimeTypeHandle handle); Here, it takes the object which refers to the type. Return Value: This method returns the type referenced by the specified RuntimeTypeHandle, or null if the Value property of handle is null.

Below programs illustrate the use of Type.GetTypeFromHandle() Method: Example 1:

csharp

// C# program to demonstrate the
// Type.GetTypeFromHandle() Method
using System;
using System.Globalization;
using System.Reflection;

class GFG {

    // Main Method
    public static void Main()
    {

        // creating and initializing object Type
        Type type = typeof(int);

        // creating object of RuntimeTypeHandle 
        // and getting instance of type
        RuntimeTypeHandle handle = Type.GetTypeHandle(type);

        // Getting the type referenced by
        // the specified RuntimeTypeHandle,
        // using GetTypeFromHandle() Method
        Type outtype = Type.GetTypeFromHandle(handle);

        // Display the Result
        Console.WriteLine("Type referenced is {0}", outtype);
        Console.WriteLine("Attributes are: " + outtype.Attributes);
    }
}

Output:

Type referenced is System.RuntimeType
Attributes are: AutoLayout, AnsiClass, Class, SequentialLayout, Serializable, BeforeFieldInit

Example 2:

csharp

// C# program to demonstrate the
// Type.GetTypeFromHandle() Method
using System;
using System.Globalization;
using System.Reflection;

// Defining Empty struct
struct Empty {}

class GFG {

    // Main Method
    public static void Main()
    {

        // creating and initializing object Type
        Type type = typeof(Empty);

        // creating object of RuntimeTypeHandle 
        // and getting instance of type
        RuntimeTypeHandle handle = Type.GetTypeHandle(type);

        // Getting the type referenced by
        // the specified RuntimeTypeHandle,
        // using GetTypeFromHandle() Method
        Type outtype = Type.GetTypeFromHandle(handle);

        // Display the Result
        Console.WriteLine("Type referenced is {0}", outtype);
        Console.WriteLine("Attributes are: " + outtype.Attributes);
    }
}

Output:

Type referenced is System.RuntimeType
Attributes are: AutoLayout, AnsiClass, Class, SequentialLayout, Serializable, BeforeFieldInit
