Uri.IsLoopback Uri.IsLoopback Uri.IsLoopback Uri.IsLoopback Property

定義

指定した Uri がローカル ホストを参照するかどうかを示す値を取得します。Gets whether the specified Uri references the local host.

public:
 property bool IsLoopback { bool get(); };
public bool IsLoopback { get; }
member this.IsLoopback : bool
Public ReadOnly Property IsLoopback As Boolean

プロパティ値

この Boolean がローカル ホストを参照する場合は true 値が Uri。それ以外の場合は falseA Boolean value that is true if this Uri references the local host; otherwise, false.

例外

このインスタンスは相対 URI を表します。このプロパティは、絶対 URI でのみ有効です。This instance represents a relative URI, and this property is valid only for absolute URIs.

次の例では、作成、Uriインスタンスし、ローカル ホストを参照しているかどうかを決定します。The following example creates a Uri instance and determines whether it references a local host.

Uri^ uriAddress2 = gcnew Uri( "file://server/filename.ext" );
Console::WriteLine( uriAddress2->LocalPath );
Console::WriteLine( "Uri {0} a UNC path", uriAddress2->IsUnc ? (String^)"is" : "is not" );
Console::WriteLine( "Uri {0} a local host", uriAddress2->IsLoopback ? (String^)"is" : "is not" );
Console::WriteLine( "Uri {0} a file", uriAddress2->IsFile ? (String^)"is" : "is not" );
// The example displays the following output:
//    \\server\filename.ext
//    Uri is a UNC path
//    Uri is not a local host
//    Uri is a file
Uri uriAddress2 =  new Uri("file://server/filename.ext");
Console.WriteLine(uriAddress2.LocalPath);
Console.WriteLine("Uri {0} a UNC path", uriAddress2.IsUnc ? "is" : "is not");
Console.WriteLine("Uri {0} a local host", uriAddress2.IsLoopback ? "is" : "is not");
Console.WriteLine("Uri {0} a file", uriAddress2.IsFile ? "is" : "is not");
// The example displays the following output:
//    \\server\filename.ext
//    Uri is a UNC path
//    Uri is not a local host
//    Uri is a file
Dim uriAddress2 As New Uri("file://server/filename.ext")
Console.WriteLine(uriAddress2.LocalPath)
Console.WriteLine("Uri {0} a UNC path", IIf(uriAddress2.IsUnc, "is", "is not")) 'TODO: For performance reasons this should be changed to nested IF statements
Console.WriteLine("Uri {0} a local host", IIf(uriAddress2.IsLoopback, "is", "is not")) 'TODO: For performance reasons this should be changed to nested IF statements
Console.WriteLine("Uri {0} a file", IIf(uriAddress2.IsFile, "is", "is not")) 'TODO: For performance reasons this should be changed to nested IF statements
' The example displays the following output:
'    \\server\filename.ext
'    Uri is a UNC path
'    Uri is not a local host
'    Uri is a file

注釈

IsLoopback 返しますtrue場合、このインスタンスの作成時に指定された URI が 127.0.0.1、ループバック、localhost、または URI を指定しなかったかどうか、またはホスト情報 (たとえば、file:///c:Dir/file.txt)。IsLoopback returns true if the URI specified when this instance was created was 127.0.0.1, loopback, or localhost, or if the URI did not specify host information (for example, file:///c:Dir/file.txt). その他のすべての Uri 戻り値falseします。All other URIs return false.
