C# 如何使用多个JSON对象处理对API的POST请求
我有一个API，需要通过POST请求接收多张发票。传入的JSON如下所示。 我的模型看起来就像JSON对象 如果我寄一张发票，一切正常，加工正常。如果像示例一样发送两张发票，我只会获取第二张发票的数据，我假设这是因为这是最后一张要反序列化的发票。是否有一种方法可以让我循环查看发票并处理每张发票 我为自己是C和API开发的初学者而道歉C# 如何使用多个JSON对象处理对API的POST请求,c#,json,api,C#,Json,Api,我有一个API，需要通过POST请求接收多张发票。传入的JSON如下所示。 我的模型看起来就像JSON对象 如果我寄一张发票，一切正常，加工正常。如果像示例一样发送两张发票，我只会获取第二张发票的数据，我假设这是因为这是最后一张要反序列化的发票。是否有一种方法可以让我循环查看发票并处理每张发票 我为自己是C和API开发的初学者而道歉 { "Invoices": { "Invoice": { "SellerParty": { "SellerParty

在JSON对象中，同一级别上不能有多个同名属性。在代码中有多个名为Invoice的属性，这会导致问题 将发票作为JSON数组将解决无效JSON的问题。即：

另外，该网站在检查您的JSON是否有效方面是非常宝贵的编辑了我的回答，以澄清数组将修复无效的JSON，可能需要在后端进行更多的工作来实际处理每个数组项。由于您没有上传代码片段，我现在不知道您的API端点外观如何。如果它获取字符串Poststring invoices，您可以使用JArray.Parse，例如：JArray invoices=JArray.Parseinvoices；发票中的foreach var发票{//完成您的工作}
