Uri.IsFile Eigenschaft

Definition

Namespace:

System

Assemblys:

netstandard.dll, System.Runtime.dll

Quelle:

Uri.cs

Ruft einen Wert ab, der angibt, ob der angegebene Uri Datei-URI ist.

public:
 property bool IsFile { bool get(); };

public bool IsFile { get; }

member this.IsFile : bool

Public ReadOnly Property IsFile As Boolean

Eigenschaftswert

Boolean

true wenn es sich um Uri einen Datei-URI handelt; andernfalls false.

Ausnahmen

InvalidOperationException

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

Beispiele

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

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

Hinweise

Die IsFile Eigenschaft ist true , wenn die Scheme Eigenschaft gleich ist UriSchemeFile.
