FileWebResponse.ContentType プロパティ
アセンブリ: System (system.dll 内)


ContentType プロパティは、ファイル システム リソースのコンテンツ タイプを格納します。ContentType の値は、常に "binary/octet-stream" です。

ContentType プロパティを使用して、ファイル システム リソースのコンテンツ タイプを取得する例を次に示します。
Public Shared Sub GetPage(url As [String]) Try Dim fileUrl As New Uri("file://" + url) ' Create a 'FileWebrequest' object with the specified Uri Dim myFileWebRequest As FileWebRequest = CType(WebRequest.Create(fileUrl), FileWebRequest) ' Send the 'fileWebRequest' and wait for response. Dim myFileWebResponse As FileWebResponse = CType(myFileWebRequest.GetResponse(), FileWebResponse) ' The ContentLength and ContentType received as headers in the response object are also exposed as properties. ' These provide information about the length and type of the entity body in the response. Console.WriteLine(ControlChars.Cr + "Content length :{0}, Content Type : {1}", myFileWebResponse.ContentLength, myFileWebResponse.ContentType) myFileWebResponse.Close() Catch e As WebException Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "The Reason for failure is : {0}", e.Status) Catch e As Exception Console.WriteLine(ControlChars.Cr + "The following exception was raised : {0}", e.Message) End Try
