autocomplete - Mudblazor 显示值 @bind-Value 与预期不符

Question

例子

如何像这样显示@bind-value：设计值

像这样的代码：

产品.cs

namespace Shared.Domains
{
  public class Product
  {
     public string Name { get; set; }
     public string Design { get; set; }
  }
}

ProductsController.cs (Web API)

[HttpGet("get")]
public async Task<ActionResult<List<Product>>> Get()
{
  return await _context.Products.ToListAsync();
}

ProductDetails.razor（代码）

  private Product design;

  private async Task<IEnumerable<Product>> Design(string value)
  {
    var data = await HttpClient.GetFromJsonAsync<List<Product>>("/products/get");
    data = data.Select(x => new Product
                            {
                              Design = x.Design
                            }).ToList();

    // if text is null or empty, show complete list
    if (string.IsNullOrEmpty(value)) 
      return data;

    return data.Where(x => x.Design.Contains(value, StringComparison.InvariantCultureIgnoreCase));
  }

ProductDetails.razor（剃须刀）

          <MudAutocomplete T="Product" Label="Design" ResetValueOnEmptyText="true"
              @bind-Value="@design" SearchFunc="@Design" MaxItems="null"
              ToStringFunc="@(e=> e == null ? null : e.Design)" />
          @(design?.ToString() ?? "Not selected")

我的输出是Shared.Domains.Product

问题解决了。

应该这样输入！

@(design != null ? design.Design : "Not selected")
