C# 控制器敏感地接受来自应用程序/json负载的数据大小写

我正在用OData编写WebApi，遇到了一个问题。问题是控制器只接受区分大小写的数据。例如，当我传递

{“name”：“London”}

时，它给出了一个空对象和一个错误

属性“name”在类型“Taxes.Service.DataLayer.Models.communications”上不存在。确保仅使用由类型定义的属性名称。

。但是当我通过

{“Name”：“London”}

时，一切都正常-对象被创建，值被设置。我不知道到底出了什么问题。谢谢

BaseController.cs

public class BaseController<T> : ODataController where T : BaseModel
{
    protected readonly TaxesContext Context;

    public BaseController(TaxesContext context)
    {
        Context = context;
    }

    [HttpPost]
    public async Task<IActionResult> Post([FromBody]T baseObject)
    {
        if (!ModelState.IsValid)
        {
            var errors = ModelState
                .SelectMany(x => x.Value.Errors, (y, z) => z.Exception.Message);

            return BadRequest(errors);
        }

        await Context.Set<T>().AddAsync(baseObject);
        await Context.SaveChangesAsync();
        return Created(baseObject);
    }
}
