Examples

The following example shows a few representative features of Type. The C# typeof operator (GetType operator in Visual Basic) is used to get a Type object representing String. From this Type object, the GetMethod method is used to get a MethodInfo representing the String.Substring overload that takes a starting location and a length.

To identify the overload signature, the code example creates a temporary array containing two Type objects representing int (Integer in Visual Basic).

The code example uses the MethodInfo to invoke the Substring method on the string "Hello, World!", and displays the result.

#using <System.dll>

using namespace System;
using namespace System::Reflection;

void main()
{
    // Get a Type object representing the System.String type.
    Type^ t = String::typeid;

    MethodInfo^ substr = t->GetMethod("Substring", 
        gcnew array<Type^> { int::typeid, int::typeid });

    Object^ result = 
        substr->Invoke("Hello, World!", gcnew array<Object^> { 7, 5 });
    Console::WriteLine("{0} returned \"{1}\".", substr, result);
}

/* This code example produces the following output:

System.String Substring(Int32, Int32) returned "World".
 */

using System;
using System.Reflection;

class Example
{
    static void Main()
    {
        Type t = typeof(String);

        MethodInfo substr = t.GetMethod("Substring", 
            new Type[] { typeof(int), typeof(int) });

        Object result = 
            substr.Invoke("Hello, World!", new Object[] { 7, 5 });
        Console.WriteLine("{0} returned \"{1}\".", substr, result);
    }
}

/* This code example produces the following output:

System.String Substring(Int32, Int32) returned "World".
 */

open System

let t = typeof<String>

let substr = t.GetMethod("Substring", [| typeof<int>; typeof<int> |])

let result = substr.Invoke("Hello, World!", [| 7; 5 |])
printfn $"{substr} returned \"{result}\"."

(* This code example produces the following output:

System.String Substring(Int32, Int32) returned "World".
 *)

Imports System.Reflection

Module Example
    
    Sub Main() 

        Dim t As Type = GetType(String)
        
        Dim substr As MethodInfo = t.GetMethod("Substring", _
            New Type() { GetType(Integer), GetType(Integer) })
        
        Dim result As Object = _ 
            substr.Invoke("Hello, World!", New Object() { 7, 5 })
        Console.WriteLine("{0} returned ""{1}"".", substr, result)
    
    End Sub 
End Module

' This code example produces the following output:
'
'System.String Substring(Int32, Int32) returned "World".
