如何导入C#词典中定义的类型?

当对象的属性是字典并且其值是自定义类型时,我正在努力找出如何生成我的imports行。

我的DTO / C#类定义如下。我的.tst文件中的Imports函数没有意识到它需要导入Status类型,类似于它导入ProjectDTO的方式。

是否可以获取.tst文件中字典值的类型?

C#文件

[TypeScript]
public class ActiveProjectsViewModel
{
    public List<ProjectDTO> Projects { get; set; }

    public Dictionary<int,Status> Statuses { get; set; }

    public bool EditModeAvailable { get; set; }
}

.tst文件

 ${
string Imports(Class c)
        {
            var props = c.Properties.Where(p=>!p.Attributes.Any(a => String.Equals(a.name, "TypeScriptIgnore", StringComparison.OrdinalIgnoreCase)));

            IEnumerable<Type> types = props
                .Select(p => p.Type)
                .Where(t => !t.IsPrimitive || t.IsEnum)
                .Select(t => t.IsGeneric ? t.TypeArguments.First() : t)
                .Where(t => !t.Attributes.Any(a => String.Equals(a.name, "TypeScriptIgnore", StringComparison.OrdinalIgnoreCase)))
                .Distinct();

            return string.Join(Environment.NewLine, types.Select(t => $"import {{ {t.Name} }} from './{t.Name}';").Distinct());
        }
    }

    $Classes()[
    $Imports

    export class $Name {
        $Properties($PropertyIsNotIgnored)[        
        public $name: $Type = $Type[$Default];]
        $BaseClass[$Properties($PropertyIsNotIgnored)[
        public $name: $Type = $Type[$Default];]]
    }]


    $Enums(*)[
    export enum $Name {
        $Values[
        $Name = $Value][,]
    }]

产生此文件:

import { ProjectDTO } from './ProjectDTO';

export class ActiveProjectsViewModel {

    public projects: ProjectDTO[] = [];        

    public statuses: { [key: number]: Status; } = {};        

    public editModeAvailable: boolean = false;

}

来自打字机的创建者,发布在这里:https://github.com/frhagn/Typewriter/issues/282  看起来字典中定义的类型可以使用以下方法派生。

SelectMany行是添加的关键。

string Imports(Class c)
{
    var props = c.Properties.Where(p => !p.Attributes.Any(a => String.Equals(a.name, "TypeScriptIgnore", StringComparison.OrdinalIgnoreCase)));

    IEnumerable<Type> types = props
        .Select(p => p.Type)
        .SelectMany(t => t.IsGeneric ? t.TypeArguments : new[] { t } as IEnumerable<Type>)
        .Where(t => !t.IsPrimitive || t.IsEnum)
        .Where(t => !t.Attributes.Any(a => String.Equals(a.name, "TypeScriptIgnore", StringComparison.OrdinalIgnoreCase)))
        .Distinct();

    return string.Join(Environment.NewLine, types.Select(t => $"import {{ {t.Name} }} from './{t.Name}';").Distinct());
}
