Methods

BuildDIParams(IServiceProvider?, IEnumerable<object?>?, ParameterInfo[])

Convenience method to build DI parameters for a contructor or method.

public static object?[] BuildDIParams(IServiceProvider? serviceProvider, IEnumerable<object?>? services, ParameterInfo[] parameters)

Parameters

serviceProvider IServiceProvider

the service provider to look up for services

services IEnumerable<object>

additional services to look up

parameters ParameterInfo[]

Returns

object[]

Remarks

services takes precedence over serviceProvider if both are provided.

BuildDIParams(IServiceProvider?, IEnumerable<object?>?, Type[])

Convenience method to build DI parameters for a contructor or method.

public static object?[] BuildDIParams(IServiceProvider? serviceProvider, IEnumerable<object?>? services, Type[] parameters)

Parameters

serviceProvider IServiceProvider

the service provider to look up for services

services IEnumerable<object>

additional services to look up

parameters Type[]

Returns

object[]

Remarks

services takes precedence over serviceProvider if both are provided.

BuildDIParams(IServiceProvider, ParameterInfo[])

Convenience method to build DI parameters for a contructor or method.

public static object?[] BuildDIParams(IServiceProvider serviceProvider, ParameterInfo[] parameters)

Parameters

serviceProvider IServiceProvider

the service provider to look up for services

parameters ParameterInfo[]

Returns

object[]

BuildDIParams(IServiceProvider, Type[])

Convenience method to build DI parameters for a contructor or method.

public static object?[] BuildDIParams(IServiceProvider serviceProvider, Type[] parameters)

Parameters

CreateInstance<T>(IServiceProvider?, IEnumerable<object?>?, Type)

Convenience method to create an instance of a class with constructor-based DI.

public static T? CreateInstance<T>(IServiceProvider? serviceProvider, IEnumerable<object?>? services, Type objType)

Parameters

serviceProvider IServiceProvider

the service provider to look up for services

services IEnumerable<object>

additional services to look up

objType Type

Returns

T

Type Parameters

T

Remarks

null is returned if objType is not assignable to T.
services takes precedence over serviceProvider if both are provided.
The first available constructor is used to create the instance. If the class has multiple constructors, which one is chosen is not guaranteed.

CreateInstance<T>(IServiceProvider?, IEnumerable<object?>?, Type, ParameterInfo[])

Convenience method to create an instance of a class with constructor-based DI.

public static T? CreateInstance<T>(IServiceProvider? serviceProvider, IEnumerable<object?>? services, Type objType, ParameterInfo[] constructorParams)

Parameters

serviceProvider IServiceProvider

the service provider to look up for services

services IEnumerable<object>

additional services to look up

objType Type

constructorParams ParameterInfo[]

Returns

T

Type Parameters

T

Remarks

null is returned if objType is not assignable to T.
services takes precedence over serviceProvider if both are provided.
The first constructor whose parameters match the constructorParams is used to create the instance.

CreateInstance<T>(IServiceProvider?, IEnumerable<object?>?, Type, Type[])

Convenience method to create an instance of a class with constructor-based DI.

Parameters

serviceProvider IServiceProvider

the service provider to look up for services

services IEnumerable<object>
