Obor názvů:

System

Sestavení:

netstandard.dll, System.Runtime.dll

Zdroj:

Uri.cs

Získá hodnotu, která určuje, zda zadaný Uri je identifikátor URI souboru.

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

public bool IsFile { get; }

member this.IsFile : bool

Public ReadOnly Property IsFile As Boolean

Hodnota vlastnosti

Boolean

true pokud je identifikátor Uri URI souboru, falsejinak .

Výjimky

InvalidOperationException

Tato instance představuje relativní identifikátor URI a tato vlastnost je platná pouze pro absolutní identifikátory URI.

Příklady

Následující příklad vytvoří Uri instanci a určí, zda se jedná o identifikátor URI souboru.

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

Poznámky

Vlastnost IsFile je true , když se Scheme vlastnost rovná UriSchemeFile.
