我有一些更复杂的物体。 班级电子邮件列表

public class emailist
{
    public String id { get; set; }
    public String emailaddress { get; set; }
    public String name { get; set; }
}   

A 类 emailRecipientList

public class emailRecipientList
{
    public String procedure { get; set; }
    public String server { get; set; }
    public String filename { get; set; }
    public String fileid { get; set; }
    public List<emailist> emaillists { get; set; }

}

还有一个任务

public async Task<System.Xml.XmlElement> postUploadEmailRecipientList([FromBody] emailRecipientList recipientList)

Now to send the data as "application/x-www-form-urlencoded"

如果需要添加更多元素，只需不断增加数组索引即可。 我在 ASP.NET WebAPI 2 项目上对其进行了测试，并且运行良好。
