Public Overridable Function GetType (className As String) As Type

Parameters

className
String

The name of the type to locate. The name must be fully qualified with the namespace.

Returns

Type

A Type object representing the given type, if the type is in this module; otherwise, null.

Attributes
ComVisibleAttribute

Exceptions

ArgumentNullException

className is null.

TargetInvocationException

The class initializers are invoked and an exception is thrown.

ArgumentException

className is a zero-length string.

FileNotFoundException

className requires a dependent assembly that could not be found.

FileLoadException

className requires a dependent assembly that was found but could not be loaded.

-or-

The current assembly was loaded into the reflection-only context, and className requires a dependent assembly that was not preloaded.

BadImageFormatException

className requires a dependent assembly, but the file is not a valid assembly.

-or-

className requires a dependent assembly which was compiled for a version of the runtime later than the currently loaded version.

Examples

The following example displays the name of a type in the specified module.

using namespace System;
using namespace System::Reflection;

namespace ReflectionModule_Examples
{
   public ref class MyMainClass{};

}

int main()
{
   array<Module^>^moduleArray;
   moduleArray = ReflectionModule_Examples::MyMainClass::typeid->Assembly->GetModules( false );
   
   //In a simple project with only one module, the module at index
   // 0 will be the module containing these classes.
   Module^ myModule = moduleArray[ 0 ];
   Type^ myType;
   myType = myModule->GetType( "ReflectionModule_Examples.MyMainClass" );
   Console::WriteLine( "Got type: {0}", myType );
}

using System;
using System.Reflection;

namespace ReflectionModule_Examples
{
    class MyMainClass
    {
        static void Main()
        {
            Module[] moduleArray;
            
            moduleArray = typeof(MyMainClass).Assembly.GetModules(false);
            
            //In a simple project with only one module, the module at index
            // 0 will be the module containing these classes.
            Module myModule = moduleArray[0];

            Type myType;

            myType = myModule.GetType("ReflectionModule_Examples.MyMainClass");
            Console.WriteLine("Got type: {0}", myType.ToString());
        }
    }
}

Imports System.Reflection

'This code assumes that the root namespace is set to empty("").
Namespace ReflectionModule_Examples
    Class MyMainClass
        Shared Sub Main()
            Dim moduleArray() As [Module]

            moduleArray = GetType(MyMainClass).Assembly.GetModules(False)

            'In a simple project with only one module, the module at index
            ' 0 will be the module containing these classes.
            Dim myModule As [Module] = moduleArray(0)

            Dim myType As Type

            myType = myModule.GetType("ReflectionModule_Examples.MyMainClass")
            Console.WriteLine("Got type: {0}", myType.ToString())
        End Sub
    End Class
End Namespace 'ReflectionModule_Examples

Remarks

Note

If the type has been forwarded to another assembly, it is still returned by this method. For information on type forwarding, see Type Forwarding in the Common Language Runtime.

A type can be retrieved from a specific module using Module.GetType. Calling Module.GetType on the module that contains the manifest will not search the entire assembly. To retrieve a type from an assembly, regardless of which module it is in, you must call Assembly.GetType.

Examples

The following example displays the name of a type in the specified module. The throwOnError and ignoreCase parameters are specified as false.

using namespace System;
using namespace System::Reflection;

namespace ReflectionModule_Examples
{
   public ref class MyMainClass{};

}

int main()
{
   array<Module^>^moduleArray;
   moduleArray = ReflectionModule_Examples::MyMainClass::typeid->Assembly->GetModules( false );
   
   //In a simple project with only one module, the module at index
   // 0 will be the module containing this class.
   Module^ myModule = moduleArray[ 0 ];
   Type^ myType;
   myType = myModule->GetType( "ReflectionModule_Examples.MyMainClass", false, false );
   Console::WriteLine( "Got type: {0}", myType );
}

using System;
using System.Reflection;

namespace ReflectionModule_Examples
{
    class MyMainClass
    {
        static void Main()
        {
            Module[] moduleArray;
            
            moduleArray = typeof(MyMainClass).Assembly.GetModules(false);
            
            //In a simple project with only one module, the module at index
            // 0 will be the module containing this class.
            Module myModule = moduleArray[0];

            Type myType;
            myType = myModule.GetType("ReflectionModule_Examples.MyMainClass", false, false);
            Console.WriteLine("Got type: {0}", myType.ToString());
        }
    }
}

Imports System.Reflection

'This code assumes that the root namespace is set to empty("").
Namespace ReflectionModule_Examples
    Class MyMainClass
        Shared Sub Main()
            Dim moduleArray() As [Module]

            moduleArray = GetType(MyMainClass).Assembly.GetModules(False)

            'In a simple project with only one module, the module at index
            ' 0 will be the module containing this class.
            Dim myModule As [Module] = moduleArray(0)

            Dim myType As Type
            myType = myModule.GetType("ReflectionModule_Examples.MyMainClass", False, False)
            Console.WriteLine("Got type: {0}", myType.ToString())
        End Sub
    End Class
End Namespace 'ReflectionModule_Examples

Remarks

The throwOnError parameter affects only what happens when the type is not found. It does not affect any other exceptions that might be thrown. In particular, if the type is found but cannot be loaded, TypeLoadException can be thrown even if throwOnError is false.

Note

If the type has been forwarded to another assembly, it is still returned by this method. For information on type forwarding, see Type Forwarding in the Common Language Runtime.

A type can be retrieved from a specific module using Module.GetType. Calling Module.GetType on the module that contains the manifest will not search the entire assembly. To retrieve a type from an assembly, regardless of which module it is in, you must call Assembly.GetType.
