定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得 Boolean 值，指出要求是否有關聯的主體資料。
public:
property bool HasEntityBody { bool get(); };public bool HasEntityBody { get; }member this.HasEntityBody : boolPublic ReadOnly Property HasEntityBody As Boolean屬性值
如果要求有關聯的主體資料，則為 true，否則為 false。
範例
下列程式代碼範例示範如何使用這個屬性。
public static void ShowRequestData (HttpListenerRequest request)
{
if (!request.HasEntityBody)
{
Console.WriteLine("No client data was sent with the request.");
return;
}
System.IO.Stream body = request.InputStream;
System.Text.Encoding encoding = request.ContentEncoding;
System.IO.StreamReader reader = new System.IO.StreamReader(body, encoding);
if (request.ContentType != null)
{
Console.WriteLine("Client data content type {0}", request.ContentType);
}
Console.WriteLine("Client data content length {0}", request.ContentLength64);
Console.WriteLine("Start of client data:");
// Convert the data to a string and display it on the console.
string s = reader.ReadToEnd();
Console.WriteLine(s);
Console.WriteLine("End of client data:");
body.Close();
reader.Close();
// If you are finished with the request, it should be closed also.
}
Public Shared Sub ShowRequestData(ByVal request As HttpListenerRequest)
If Not request.HasEntityBody Then
Console.WriteLine("No client data was sent with the request.")
Return
End If
Dim body As System.IO.Stream = request.InputStream
Dim encoding As System.Text.Encoding = request.ContentEncoding
Dim reader As System.IO.StreamReader = New System.IO.StreamReader(body, encoding)
If request.ContentType IsNot Nothing Then
Console.WriteLine("Client data content type {0}", request.ContentType)
End If
Console.WriteLine("Client data content length {0}", request.ContentLength64)
Console.WriteLine("Start of client data:")
' Convert the data to a string and display it on the console.
Dim s As String = reader.ReadToEnd()
Console.WriteLine(s)
Console.WriteLine("End of client data:")
body.Close()
reader.Close()
' If you are finished with the request, it should be closed also.
End Sub
備註
例如，使用 POST 方法將數據傳送至伺服器的要求應該具有實體主體。
