Ebay API C#取消不带AddDispute的订单

Cancel eBay order via API

但是我不希望每次取消都引起争议.我想做的是能够以编程方式取消订单而不会引起争议.由于它在GUI中可用,因此似乎应该可行.在GUI中,如果您查找订单并单击订单屏幕的下拉菜单,则会显示一个取消按钮.然后在下一个屏幕上,询问取消原因,并提供两个选项.我似乎在任何地方都找不到此文档.我使用API​​取消订单所能找到的所有内容都会引发争议.有谁知道如何用这种方法取消订单？

用KEVINUK的代码示例更新答案：

这是我的工作示例.我将其用作布尔值,以让我知道取消请求是否成功,以便我可以知道从那里去哪里.
