C# Dynamic Proxy error using class.

[mehmetuken]

public class GetProductsInput : PagedAndSortedResultRequestDto
    {
        public ProductQueryFilter QueryFilter { get; set; }

        public GetProductsInput()
        {
            QueryFilter = new ProductQueryFilter();
        }
    }

My ProductsAppService get input like this c# dynamic proxy if not set any QueryFilter value request like

https://localhost:44315/api/app/product&Sorting=&SkipCount=0&MaxResultCount=10&api-version=1.0

first element starts & character. I set QueryFilter.Name = ""; empty it's run correctly.
https://localhost:44315/api/app/product?QueryFilter.Name=&Sorting=&SkipCount=0&MaxResultCount=10&api-version=1.0

i think first element issue dynamic proxy UrlBuilder.

hi @mehmetuken

• Your ABP Framework version.
• Steps needed to reproduce the problem.

[mehmetuken]

Sorry.
Abp Framework Version 4.1.1 stable

Steps,

public interface IProductAppService : ICrudAppService<
        ProductDto,
        Guid,
        GetProductsInput,
        CreateUpdateProductDto>

my ProductQueryFilter class. i use repository custom filter.

public class ProductQueryFilter
    {
        public string Sku { get; set; }

        public string Name { get; set; }
}

my input class

public class GetProductsInput : PagedAndSortedResultRequestDto
    {
        public ProductQueryFilter QueryFilter { get; set; }

        public GetProductsInput()
        {
            QueryFilter = new ProductQueryFilter();
        }
    }

i follow blazor Web Application Development Tutorial my input have class ProductQueryFilter i don't set any query filter dynamic proxy create url like this
https://localhost:44315/api/app/product&Sorting=&SkipCount=0&MaxResultCount=10&api-version=1.0 and got 404 error. Because first attribute start & character.

Thanks I will check this.

I can't rep[roduce it in the unit test method. Can you share a sample project?

[mehmetuken]

I find i think is irrelevant but problem is any empty generic input set.

My example

public class ProductQueryFilter
    {
        public string Sku { get; set; }

        public string Name { get; set; }

        public Guid? CategoryId { get; set; }

        public IEnumerable<Guid> Attributes { get; set; }

        public ProductQueryFilter()
        {
            Attributes = new List<Guid>();
        }
    }

abp/framework/src/Volo.Abp.Http.Client/Volo/Abp/Http/Client/DynamicProxying/UrlBuilder.cs

Line 80 in 1771d34

if (value == null)

in here is not null but is empty generic using firstParam but not set urlbuilder because is empty.
