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。
