Uri.IsFile Eigenschaft

Definition

Ruft einen Wert ab, der angibt, ob es sich bei dem angegebenen Uri um einen Datei-URI handelt.

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

Eigenschaftswert

true , wenn es sich bei um Uri einen Datei-URI handelt, falseandernfalls .

Ausnahmen

Diese Instanz stellt einen relativen URI dar, diese Eigenschaft ist jedoch nur für absolute URIs gültig.

Beispiele

Im folgenden Beispiel wird ein Uri instance erstellt und bestimmt, ob es sich um einen Datei-URI handelt.

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
let uriAddress2 = Uri "file://server/filename.ext"
printfn $"{uriAddress2.LocalPath}"
printfn $"""Uri {if uriAddress2.IsUnc then "is" else "is not"} a UNC path"""
printfn $"""Uri {if uriAddress2.IsLoopback then "is" else "is not"} a local host"""
printfn $"""Uri {if uriAddress2.IsFile then "is" else "is not"} a file"""
// 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
