Provides a generic way to rehydrate serialized objects.

public class MemberParser

Inheritance

MemberParser

Examples

The following example shows how to hydrate a type from named reflection arguments.

using System;
using System.Collections.Generic;
using System.Linq;
using Cuemon.Reflection;

namespace MyApp.Examples;

public static class MemberParserExample
{
    public static void Demonstrate()
    {
        var arguments = new List<MemberArgument>
        {
            new("sku", "SKU-42"),
            new("price", 19.95m),
            new("stock", 12)
        };

        var parser = new MemberParser(typeof(CatalogItem), arguments);
        var item = (CatalogItem)parser.CreateInstance(ctor => ctor.GetParameters().Length == 2);

        Console.WriteLine(item.Sku);
        Console.WriteLine(item.Price);
        Console.WriteLine(item.Stock);
        Console.WriteLine(string.Join(", ", parser.ProcessedMemberArguments.Select(argument => argument.Name)));
    }
}

public sealed class CatalogItem
{
    public CatalogItem(string sku, decimal price)
    {
        Sku = sku;
        Price = price;
    }

    public string Sku { get; }

    public decimal Price { get; }

    public int Stock { get; set; }
}

Constructors

MemberParser(Type, IEnumerable<MemberArgument>)

Initializes a new instance of the MemberParser class.

public MemberParser(Type source, IEnumerable<MemberArgument> memberArguments)

Parameters

source Type

The Type of the source to rehydrate.

memberArguments IEnumerable<MemberArgument>

The arguments associated with the source.

Properties

MemberArguments

Gets the arguments associated with the source to rehydrate.

public IEnumerable<MemberArgument> MemberArguments { get; }

Property Value

IEnumerable<MemberArgument>

The arguments associated with the source to rehydrate.

ProcessedMemberArguments

Gets the processed arguments associated with the source to rehydrate.

public IEnumerable<MemberArgument> ProcessedMemberArguments { get; }

Property Value

IEnumerable<MemberArgument>

The arguments associated with the source to rehydrate.

Remarks

This can be useful for debugging why an instance is not rehydrated as expected.

Source

Gets the Type of the source to rehydrate.

public Type Source { get; }

Property Value

Type

The Type of the source to rehydrate.

Methods

CreateInstance(Func<ConstructorInfo, bool>)

Creates an instance of the Type associated with this parser.

public object CreateInstance(Func<ConstructorInfo, bool> predicate = null)

Parameters

predicate Func<ConstructorInfo, bool>

A function to test each ConstructorInfo for a condition.

Returns

object

An instance equivalent to the Type associated with this parser.
