TypeBuilder::DefineMethod Method (String^, MethodAttributes, CallingConventions, Type^, array<Type^>^, array<Type^>^, array<Type^>^, array<array<Type^>^>^, array<array<Type^>^>^)
Adds a new method to the type, with the specified name, method attributes, calling convention, method signature, and custom modifiers.
Assembly: mscorlib (in mscorlib.dll)
public: MethodBuilder^ DefineMethod( String^ name, MethodAttributes attributes, CallingConventions callingConvention, Type^ returnType, array<Type^>^ returnTypeRequiredCustomModifiers, array<Type^>^ returnTypeOptionalCustomModifiers, array<Type^>^ parameterTypes, array<array<Type^>^>^ parameterTypeRequiredCustomModifiers, array<array<Type^>^>^ parameterTypeOptionalCustomModifiers )
Parameters
- name
-
Type:
System::String^
The name of the method. name cannot contain embedded nulls.
- attributes
-
Type:
System.Reflection::MethodAttributes
The attributes of the method.
- callingConvention
-
Type:
System.Reflection::CallingConventions
The calling convention of the method.
- returnType
-
Type:
System::Type^
The return type of the method.
- returnTypeRequiredCustomModifiers
-
Type:
array<System::Type^>^
An array of types representing the required custom modifiers, such as IsConst, for the return type of the method. If the return type has no required custom modifiers, specify null.
- returnTypeOptionalCustomModifiers
-
Type:
array<System::Type^>^
An array of types representing the optional custom modifiers, such as IsConst, for the return type of the method. If the return type has no optional custom modifiers, specify null.
- parameterTypes
-
Type:
array<System::Type^>^
The types of the parameters of the method.
- parameterTypeRequiredCustomModifiers
-
Type:
array<array<System::Type^>^>^
An array of arrays of types. Each array of types represents the required custom modifiers for the corresponding parameter, such as IsConst. If a particular parameter has no required custom modifiers, specify null instead of an array of types. If none of the parameters have required custom modifiers, specify null instead of an array of arrays.
- parameterTypeOptionalCustomModifiers
-
Type:
array<array<System::Type^>^>^
An array of arrays of types. Each array of types represents the optional custom modifiers for the corresponding parameter, such as IsConst. If a particular parameter has no optional custom modifiers, specify null instead of an array of types. If none of the parameters have optional custom modifiers, specify null instead of an array of arrays.
Return Value
Type: System.Reflection.Emit::MethodBuilder^A MethodBuilder object representing the newly added method.
| Exception | Condition |
|---|---|
| ArgumentException | The length of name is zero. -or- The type of the parent of this method is an interface, and this method is not virtual (Overridable in Visual Basic). -or- The size of parameterTypeRequiredCustomModifiers or parameterTypeOptionalCustomModifiers does not equal the size of parameterTypes. |
| ArgumentNullException | name is null. |
| InvalidOperationException | The type was previously created using CreateType. -or- For the current dynamic type, the IsGenericType property is true, but the IsGenericTypeDefinition property is false. |
Use this overload if you need to specify custom modifiers. If you need to specify custom modifiers after the method has been created, as you would, for example, with a generic method whose parameter types are specified by its generic type parameters, you can use the DefineMethod(String^, MethodAttributes) or DefineMethod(String^, MethodAttributes, CallingConventions) method overloads to define the method and then use the MethodBuilder::SetSignature method to define the parameter and return types with custom modifiers.
