Examples

Arguments

X

Methods

Returns a default instantiated value for value types, and null for reference types

public static object Default(this Type type)

X

Methods arguments

Type	Name	Description
System.Type	type

X

Type	Description
System.Object

Returns the first generic type specified, or null

Optional: pass in higher index to return a different type argument

public static Type GetTypeArgument(this Type type, int index = 0)

X

class Car
{
}

var type = typeof(List<Car>);
var genericType = type.GetTypeArgument();
// genericType is now 'typeof(Car)'

X

Methods arguments

Type	Name	Description
System.Type	type
System.Int32	index

X

Type	Description
System.Type

Returns all generic types found or null

public static Type[] GetTypeArguments(this Type type)

X

class Car
{
}

var type = typeof(List<Car>);
var genericType = type.GetTypeArguments();
// genericType is now an array of Types with 1 item: 'typeof(Car)'

X

Methods arguments

Type	Name	Description
System.Type	type

X

Type	Description
System.Type[]

Returns the Name of the Type that makes 'most sense'

For generics, such as a IList, List, Dictionary, it will return the Name of the first generic Type specified

public static string GetTypeName(this Type type)

X

class Car
{
}

var result = typeof(Car).GetTypeName();
// result is "Car"

var list = new List<Car>
var result = list.GetType().GetTypeName();
// result is "Car"

var result = typeof(List<Car>).GetTypeName();
// result is "Car"

var result = typeof(Car[]).GetTypeName();
// result is "Car"

X

Methods arguments

Type	Name	Description
System.Type	type

X

Type	Description
System.String	The type name

Check if 'thisType' inherits or implements 'type

False if both types are the same

public static bool Inherits(this Type thisType, Type type)

X

class Car : IVehicle 
{
}

var result = typeof(Car).Inherits(typeof(IVehicle));
// result is true, as it inherits/implements IVehicle

var result = typeof(Car).Inherits(typeof(Car));
// result is false, as Car cannot inherit/implement itself

X

Methods arguments

Type	Name	Description
System.Type	thisType
System.Type	type

X

Type	Description
System.Boolean	true or false

Checks if type is a dictionary

public static bool IsDictionary(this Type type)

X

var dictionary = new Dictionary<string, string>();

var result = dictionary.IsDictionary();
//result is true

X

Methods arguments

Type	Name	Description
System.Type	type

X

Type	Description
System.Boolean	true or false

Returns true if internal else false

public static bool IsInternal(this Type type)

X

var t = typeof(Car);
var isInternal = t.IsInternal();

X

Methods arguments

Type	Name	Description
System.Type	type

X

Type	Description
System.Boolean	True or false

Check if type is a KeyValuePair generic

public static bool IsKeyValuePair(this Type type)

X

Methods arguments

Type	Name	Description
System.Type	type

X

Type	Description
System.Boolean	true or false

Check if type is a list or array

Remarks

X

Does not check on IList, nor Dictionary, just List or Array

public static bool IsListOrArray(this Type type)

X

var array = new string[] { "" };

var result = array.GetType().IsListOrArray();
//result is true

X

Methods arguments

Type	Name	Description
System.Type	type

X

Type	Description
System.Boolean	true or false

Set a static member on a Type, no matter if it is internal or private

public static void SetStaticMember(this Type type, string memberName, object value)

X

Methods arguments

Type	Name	Description
System.Type	type
System.String	memberName
System.Object	value
