備註

列舉 C# 或 Microsoft Visual Basic 中的集合

您可以在 C# 或 Microsoft Visual Basic 中逐一查看 HttpMultipartFormDataContent 物件。 在許多情況下，例如使用 foreach 語法，編譯程式會為您執行此轉換，而且您不需要明確地轉換成 IEnumerable<IHttpContent> 。 如果您需要明確轉換，例如，如果您想要呼叫 GetEnumerator，請轉換成 [IEnumerable< T>] (/dotnet/api/system.collections.generic.ienumerable-1？view=dotnet-uwp-10.0&preserve-view=true 搭配 IHttpContent 条件約束。
