This article mainly explains "what are the common methods of reflection in C# generic methods". The content of the explanation in this article is simple and clear, and it is easy to learn and understand. let's study and learn "what are the common methods of reflection in C# generic methods"?

Reflection commonly used in C # generic methods: because the common language runtime (CLR) can access generic type information at run time, you can use reflection to get information about generic types in the same way as for non-generic types. In .NET Framework 2.0, several new members have been added to the Type class to enable runtime information for generic types. The System.Reflection.Emit namespace also contains new members that support generics.

System.Type members of common reflection methods in C # generic methods

◆ IsGenericType

Returns true if the type is generic.

◆ GetGenericArguments

Returns an array of Type objects that represent the type variables provided for the construction type, or the type parameters defined by the generic type.

◆ GetGenericTypeDefinition

Returns the underlying generic type definition of the current construction type.

◆ GetGenericParameterConstraints

Returns an array of Type objects that represent the current generic type parameter constraint.

◆ ContainsGenericParameters

Returns true if the type or any of its enclosed types or methods contains type parameters that are not of a specific type.

◆ GenericParameterAttributes

Gets a combination of GenericParameterAttributes flags that describe the special constraints of the current generic type parameters.

◆ GenericParameterPosition

For a Type object that represents a type parameter, gets the position of the type parameter in the list of type parameters defined by the generic type definition or generic method definition that declares the type parameter.

◆ IsGenericParameter

Gets a value indicating whether the current Type represents a type parameter defined by a generic type or a generic method.

◆ IsGenericTypeDefinition

Gets a value indicating whether the current Type represents a generic type definition that can be used to construct other generic types. Returns true if the type represents the definition of a generic type.

◆ DeclaringMethod

Returns a generic method that defines the current generic type parameter, or a null value if the type parameter is not defined by a generic method.

◆ MakeGenericType

Replaces the type parameters of the current generic type definition with the elements of the type array and returns a Type object that represents the resulting constructed type.

In addition, new members have been added to the MethodInfo class to enable runtime information for generic methods.

System.Reflection.MemberInfo members of common reflection methods in C # generic methods

◆ IsGenericMethod

Returns true if the method is generic.

◆ GetGenericArguments

Returns an array of Type objects that represent type variables that construct generic methods, or type parameters defined by generic methods.

◆ GetGenericMethodDefinition

Returns the underlying generic method definition of the current constructor.

◆ ContainsGenericParameters

Returns true if the method or any of its enclosed types contains any type parameters that are not supplied with a particular type.

◆ IsGenericMethodDefinition

Returns true if the current MethodInfo represents the definition of a generic method.

◆ MakeGenericMethod

Replaces the type parameters defined by the current generic method with the elements of the type array and returns a MethodInfo object that represents the resulting constructor.
