Mendapatkan nilai yang menunjukkan apakah yang ditentukan Uri adalah jalur konvensi penamaan universal (UNC).

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

Nilai Properti

Boolean

true Uri jika adalah jalur UNC; jika tidak, false.

Pengecualian

InvalidOperationException

Instans ini mewakili URI relatif, dan properti ini hanya valid untuk URI absolut.

Contoh

Contoh berikut membuat instans Uri dan menentukan apakah itu adalah jalur UNC.

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

Keterangan

Properti IsUnc adalah true jika instans yang ditentukan Uri adalah jalur UNC (seperti \\server\folder, //server, atau file://server/folder). Properti ini selalu mengembalikan true jika URI memiliki skema file:// dan menentukan komponen host.
