取得用戶端接受的 MIME 類型。

public:
 property cli::array <System::String ^> ^ AcceptTypes { cli::array <System::String ^> ^ get(); };

public string[]? AcceptTypes { get; }

member this.AcceptTypes : string[]

Public ReadOnly Property AcceptTypes As String()

屬性值

String[]

String 陣列，包含要求的 Accept 標頭中所指定的類型名稱，如果用戶端要求沒有包含 null 標頭，則為 Accept。

範例

下列程式代碼範例示範如何使用這個屬性。

public static void ShowRequestProperties1 (HttpListenerRequest request)
{
    // Display the MIME types that can be used in the response.
    string[] types = request.AcceptTypes;
    if (types != null)
    {
        Console.WriteLine("Acceptable MIME types:");
        foreach (string s in types)
        {
            Console.WriteLine(s);
        }
    }
    // Display the language preferences for the response.
    types = request.UserLanguages;
    if (types != null)
    {
        Console.WriteLine("Acceptable natural languages:");
        foreach (string l in types)
        {
            Console.WriteLine(l);
        }
    }

    // Display the URL used by the client.
    Console.WriteLine("URL: {0}", request.Url.OriginalString);
    Console.WriteLine("Raw URL: {0}", request.RawUrl);
    Console.WriteLine("Query: {0}", request.QueryString);

    // Display the referring URI.
    Console.WriteLine("Referred by: {0}", request.UrlReferrer);

    //Display the HTTP method.
    Console.WriteLine("HTTP Method: {0}", request.HttpMethod);
    //Display the host information specified by the client;
    Console.WriteLine("Host name: {0}", request.UserHostName);
    Console.WriteLine("Host address: {0}", request.UserHostAddress);
    Console.WriteLine("User agent: {0}", request.UserAgent);
}

Public Shared Sub ShowRequestProperties1(ByVal request As HttpListenerRequest)
    ' Display the MIME types that can be used in the response.
    Dim types As String() = request.AcceptTypes

    If types IsNot Nothing Then
        Console.WriteLine("Acceptable MIME types:")

        For Each s As String In types
            Console.WriteLine(s)
        Next
    End If

    ' Display the language preferences for the response.
    types = request.UserLanguages

    If types IsNot Nothing Then
        Console.WriteLine("Acceptable natural languages:")

        For Each l As String In types
            Console.WriteLine(l)
        Next
    End If

    ' Display the URL used by the client.
    Console.WriteLine("URL: {0}", request.Url.OriginalString)
    Console.WriteLine("Raw URL: {0}", request.RawUrl)
    Console.WriteLine("Query: {0}", request.QueryString)

    ' Display the referring URI.
    Console.WriteLine("Referred by: {0}", request.UrlReferrer)

    ' Display the HTTP method.
    Console.WriteLine("HTTP Method: {0}", request.HttpMethod)

    ' Display the host information specified by the client.
    Console.WriteLine("Host name: {0}", request.UserHostName)
    Console.WriteLine("Host address: {0}", request.UserHostAddress)
    Console.WriteLine("User agent: {0}", request.UserAgent)
End Sub

備註

Accept標頭是空格分隔的多用途因特網郵件延伸模組字串， (MIME) 類型名稱 (例如 image/jpeg ，) ，這表示客戶端準備好在回應中接受和處理MIME類型。 專案 */* 表示用戶端接受任何 MIME 類型。 如需標頭的詳細 Accept 描述，請參閱 RFC 2616，網址為 https://www.rfc-editor.org。

如需要求標頭的完整清單，請參閱 HttpRequestHeader 列舉。
