c# - 使用 WCF Web 服务发送 1 个包含 100 万个整数的数组等于大超时？

Question

我创建了一个与我的应用程序 C# 相关的 webService。

所有方法都非常有效。但是，函数有问题“TimeOut”。此方法应返回一个整数数组，其中包含大约 [1,000,000] (100 万) 个整数。我正确地获取了数据，但在调用我的方法后大约 4-5 分钟!一个表 100 万个整数等待大约 5 分钟是否正常？我发现这对我的应用程序来说可能会花费太长时间且烦人。您知道发送大数据的解决方案或更好的方法吗？

• 其他压缩方法？
• 其他响应格式(xml、数组..)？

我认为您应该尝试对结果进行分页，以便为每个请求带来更少的数据。
