Windows 需求

範例

下列範例程式碼示範使用 HttpContentHeaderCollection 物件上的屬性來取得和設定 HTTP 內容標頭的方法。 Windows.Web.Http.Headers命名空間具有許多強型別標頭集合，以及特定 HTTP 標頭的值類別，可用來取得和設定具有驗證的標頭。

using System;
using Windows.Web.Http;
using Windows.Web.Http.Headers;

public void DemonstrateContentHeader()
{
    DemonstrateHeaderContentContentDisposition();
}

public void DemonstrateHeaderContentContentDisposition()
{
    var content = new HttpStringContent("");
    bool parsedOk = false;

    // Set the header with a string.
    HttpContentDispositionHeaderValue value;
    parsedOk = HttpContentDispositionHeaderValue.TryParse("attachment; filename=\"fname.ext\"", out value);
    content.Headers.ContentDisposition = value;

    // Set the header with a strong type.

    content.Headers.ContentDisposition = new HttpContentDispositionHeaderValue("attachment");
    content.Headers.ContentDisposition.FileName = "myfile.exe";


    // Get the strong type out
    System.Diagnostics.Debug.WriteLine("ContentDisposition filename: {0}={1}",
        content.Headers.ContentDisposition.DispositionType,
        content.Headers.ContentDisposition.FileName);

    // The ToString() is useful for diagnostics, too.
    System.Diagnostics.Debug.WriteLine("The ContentDisposition ToString() results: {0}", content.Headers.ContentDisposition.ToString());
}

備註

HttpContentHeaderCollection是 HTTP 要求或 HTTP 回應訊息上與 HTTP 內容相關聯的 HTTP 標頭集合。 HttpContentHeaderCollection物件可用來取得或設定 HTTP 內容上的特定標頭。 HttpContentHeaderCollection物件上的大部分屬性都提供特定 HTTP 標頭之容器集合的存取權。

HttpContentHeaderCollection具有建構函式，而且也會由HttpBufferContent、HttpFormUrlEncodedContent、HttpMultipartContent、HttpMultipartFormDataContent、HttpStreamContent和HttpStringContent、類別和IHttpContent介面上的 屬性傳回。

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 HttpContentHeaderCollection 物件。 在許多情況下，例如使用 foreach 語法，編譯器會為您執行此轉換，而且您不需要明確地轉換成 IEnumerable 。 如果您需要明確轉換，例如，如果您想要呼叫GetEnumerator，請將集合物件轉換成具有String和String的 KeyValuePair 作為條件約束的IEnumerable < T >。
