我有一个具有 OData 后端的 Blazor WASM 应用程序。我正在尝试配置我的一个模型的 NavigationProperty，以便我可以使用$expand=查询参数返回更多数据，但是在尝试发出PATCH请求时我不断收到以下错误（GET工作得很好）：

Microsoft.OData.ODataException: The property 'JobId' does not exist on type 'Coin.ODataOrderHeader'. Make sure to only use property names that are defined by the type or mark the type as open type.

但它确实存在！不只是在模型中：

public partial class ODataOrderHeader
{
        [Key]
        public int OrderId { get; set; }

        [Column("JobID")]
        [ForeignKey("Job")]
        public int JobId { get; set; }
        ...
        [System.Text.Json.Serialization.JsonPropertyName("Job")]
        public virtual Jobs Job { get; set; }
}

但在$metadata文档中也是如此：

<?xml version="1.0" encoding="utf-8"?>
<edmx:Edmx Version="4.0" xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx">
    <edmx:DataServices>
        <Schema Namespace="Coin" xmlns="http://docs.oasis-open.org/odata/ns/edm">
            ...
            <EntityType Name="ODataOrderHeader">
                <Key>
                    <PropertyRef Name="OrderId" />
                </Key>
                <Property Name="OrderId" Type="Edm.Int32" Nullable="false" />
                <Property Name="JobId" Type="Edm.Int32" />
                ...
                <NavigationProperty Name="Job" Type="Coin.Jobs">
                    <ReferentialConstraint Property="JobId" ReferencedProperty="JobId" />
                </NavigationProperty>
            </EntityType>
            ...
        </Schema>
    </edmx:DataServices>
</edmx:Edmx>

下面是创建模型的代码：

        private IEdmModel GetEdmModel()
        {
            var builder = new ODataConventionModelBuilder();
            builder.Namespace = "Coin";
            builder.ContainerName = "CoinContainer";
            ...
            var orders = builder.EntitySet<ODataOrderHeader>("Orders");
            return builder.GetEdmModel();
        }

我可能应该指出，ODataOrderHeader更多的是 DTO 类型，而JobsEF 脚手架类型。

下面是Simple.OData.Client调用 API 的代码：

    private async void UpdateItem()
    {
        ODataClient client = new ODataClient(new ODataClientSettings(HttpClient, new Uri("odata", UriKind.Relative)));

        await client.For<ODataOrderHeader>("Orders")
            .Key(currentOrder.OrderId)
            .Set(currentOrder)
            .UpdateEntryAsync();
    }

这是上面代码调用的控制器操作：

        [ODataRoute("/orders({key})")]
        public async Task<IActionResult> Patch([FromODataUri] int key, Delta<ODataOrderHeader> order)
        {
            if (!ModelState.IsValid)
                return BadRequest();

            ...
        }

最后，完整的错误消息：

是否有我遗漏的配置错误或控制器操作有问题？

对于将来偶然发现这一点的任何人，我能够发现更多信息。

首先，通过[IgnoreDataMember]在我的 Jobs 类上添加一些数据注释并{IgnoreUnmappedProperties = true}在实例化时添加ODataClient，我能够得到一个不同的错误。类似的东西：The key 'JobId' does not exist in the dictionary。

对于上下文，我正在尝试执行 OData 所指的“深度更新”。我想在更新父实体的同时更新子实体。但是，Simple.OData.Client 不支持深度更新或深度链接或深度创建。 这是来自 Simple.OData.Client 的 GitHub 页面的一个 5 年前的问题，其中谈到了这一点，不幸的是，这个包的开发似乎已经停止（“Simple.OData.Client 的未来”和“项目已死？”）。由于它不支持“深度更新”，它不知道如何生成请求 URL，这就是我的PATCH请求失败的原因。
